the pancreatic or common bile duct. Specifically, it reports the cholangioscopy or pancreatoscopy component of an ERCP session, and it never appears alone on a claim. Because the American Medical Association maintains the CPT code set, payers audit claims against its exact descriptor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This reference covers the official descriptor, the add-on code rules, and the valid primary code pairings. It also sets out the applicable modifiers, Medicare reimbursement context, and the ICD-10 codes most often paired with 43273. Finally, the closing sections deal with documentation requirements and the billing errors most likely to trigger a denial.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"CPT Coding Pitfalls Every Medical Practice Faces\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/vbvV5okdXKg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 id=\"h-cpt-code-43273-definition-and-clinical-description\" class=\"wp-block-heading\">CPT Code 43273: definition and clinical description<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT Code 43273 describes endoscopic pancreatoscopy or cholangioscopy performed during an endoscopic retrograde cholangiopancreatography (ERCP) procedure. To achieve this, the endoscopist introduces a small-caliber endoscope through the working channel of a duodenoscope. As a result, the physician gets direct visualization of the bile duct, the pancreatic duct, or both, which fluoroscopy alone cannot provide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike fluoroscopy, which offers a two-dimensional shadow image of ductal anatomy, cholangioscopy and pancreatoscopy allow the physician to see inside the duct directly. As a result, this matters for diagnosing indeterminate strictures, confirming stone clearance, or guiding targeted biopsies. In turn, what the endoscopist sees also feeds back into the patient&#8217;s <a href=\"https:\/\/pabau.com\/blog\/gastrointestinal-assessment\/\">gastrointestinal assessment<\/a> and treatment plan.<\/p>\n\n\n\n<table style=\"width:100%;border-collapse:separate;border-spacing:0;border-radius:12px;overflow:hidden;font-size:15px;line-height:1.5;margin:1.5em 0 2em;box-shadow:0 2px 12px rgba(0,0,0,0.08)\">\n<thead>\n<tr>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Field<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">CPT Code<\/td>\n<td style=\"padding:12px 16px;color:#374151\">43273<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Official Descriptor<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Endoscopic cannulation of papilla with direct visualization of pancreatic\/common bile duct(s) (List separately in addition to code for primary procedure).<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Code Type<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Add-on code (+43273) &#8211; must always accompany a primary code<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">CPT Section<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Surgery &#8211; Digestive System \/ Endoscopy, Endoscopic Retrograde Cholangiopancreatography<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Multiple Procedure Reduction<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Exempt &#8211; add-on codes are not subject to the 50% payment reduction<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Site of Service<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Hospital outpatient (facility) or ambulatory surgical center (ASC)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<h2 id=\"h-add-on-code-rules-and-required-primary-codes\" class=\"wp-block-heading\">Add-on code rules and required primary codes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT Code 43273 carries the add-on designation (+43273), meaning it can never appear on a claim by itself. As a result, payers will deny it automatically when billers submit it without a qualifying primary code. Instead, the valid primary ERCP codes that billers may report alongside 43273 come from the ERCP code family spanning 43260 through 43278.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing the right primary code means identifying the primary service performed during the ERCP session. For example, a diagnostic ERCP pairs with 43260, while an ERCP with sphincterotomy pairs with 43262. By contrast, neighboring upper GI endoscopy codes such as <a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-43233\/\">43233<\/a> sit outside the ERCP family and carry their own bundling rules.<\/p>\n\n\n\n<table style=\"width:100%;border-collapse:separate;border-spacing:0;border-radius:12px;overflow:hidden;font-size:15px;line-height:1.5;margin:1.5em 0 2em;box-shadow:0 2px 12px rgba(0,0,0,0.08)\">\n<thead>\n<tr>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Primary CPT Code<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Brief Descriptor<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43260<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Diagnostic ERCP<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43261<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with biopsy, single or multiple<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43262<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with sphincterotomy\/papillotomy<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43264<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with removal of calculi\/debris from biliary or pancreatic ducts<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43265<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with destruction of calculi, any method<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43270<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with ablation of tumor(s), polyp(s), or other lesion(s)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43274<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with placement of endoscopic stent into biliary or pancreatic duct<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43275<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with removal of foreign body or stent from biliary\/pancreatic duct<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43276<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with replacement of stent, biliary or pancreatic duct<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43277<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with dilation of biliary or pancreatic duct stricture(s), each duct<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43278<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with ablation of tumor(s), polyp(s), or other lesion(s), including pre- and post-dilation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">Because 43273 is an add-on code, it is also exempt from the multiple procedure payment reduction rule. Specifically, CMS add-on code policy does not apply the 50% reduction that hits secondary procedures billed with modifier 51. The full allowed amount is therefore payable alongside the primary ERCP code. Even so, verify the current NCCI edits for the year before you submit, since edit tables change quarterly.<\/p>\n\n\n        <div id=\"pro_tip\">\n            <div class=\"img\">\n                <svg width=\"42\" height=\"42\" viewBox=\"0 0 42 42\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                        d=\"M12.6383 19.5238C12.6632 21.2071 12.8734 22.9926 12.0685 24.5523C11.0341 26.8917 8.45076 28.169 7.56292 30.5918C6.63082 33.1061 7.19505 36.185 9.31371 37.9786C10.929 39.5678 13.4183 39.9873 15.6061 39.5463C17.4592 39.073 19.1049 37.8388 19.9706 36.1608C20.781 34.7141 20.7866 32.9904 20.5293 31.3985C20.1006 29.3092 18.3775 27.8705 16.9807 26.362C14.8814 24.1005 14.6684 20.6854 15.595 17.8915C16.4331 15.4768 19.0026 14.2344 20.0425 11.9461C20.7202 10.6769 20.7506 9.20327 20.6068 7.81304C20.1864 5.40098 18.3139 3.23631 15.8716 2.56674C13.9742 2.03969 11.8224 2.30052 10.1739 3.37614C8.70522 4.34688 7.5878 5.86618 7.28356 7.58178C6.76081 9.82981 7.53525 12.2822 9.20307 13.9118C10.7658 15.4741 12.4806 17.2273 12.6383 19.5238Z\"\n                        fill=\"#2BADD4\" \/>\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                        d=\"M22.7048 19.8387C22.6822 22.3279 24.4507 24.6234 26.7493 25.4682C28.0531 25.961 29.4725 25.9183 30.7989 25.5487C32.0575 24.9955 33.301 24.2237 34.0069 23.0092C34.8384 21.5811 35.2982 19.8286 34.7832 18.2094C34.3611 16.2507 32.8739 14.6541 31.0275 13.9426C28.6736 12.9595 25.8073 13.7942 24.1719 15.7001C23.2022 16.8366 22.6143 18.3326 22.7048 19.8387Z\"\n                        fill=\"#2BADD4\" \/>\n                <\/svg>\n            <\/div>\n            <div class=\"text\">\n                <h3>Pro Tip<\/h3>\n                <p>Confirm add-on status in your practice management system before claim submission. Specifically, tag +43273 only when a separate small-caliber scope entered the duct for direct visualization. However, fluoroscopy alone during the ERCP session does not qualify.<\/p>\n            <\/div>\n        <\/div>\n    \n\n\n<h2 id=\"h-is-cpt-43273-for-spyglass-only\" class=\"wp-block-heading\">Is CPT 43273 for SpyGlass only?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No. This is the most persistent misconception in ERCP billing, and it causes practices to under-bill when they use non-SpyGlass cholangioscopy systems. In fact, CPT Code 43273 applies to any technology that achieves direct endoscopic visualization of the bile duct or pancreatic duct. Instead, the only clinical criterion is that direct visualization occurred beyond what standard fluoroscopy provides.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SpyGlass DS (Boston Scientific) is the most widely recognized single-operator cholangioscopy system in the US, which is why the misconception persists. But other fiber-optic choledochoscopes, mother-baby scope systems, and alternative direct visualization technologies all qualify. Therefore, the scope manufacturer is irrelevant to code eligibility.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>SpyGlass DS:<\/strong> Qualifies &#8211; single-operator, digital, most commonly used<\/li>\n\n\n\n<li><strong>Fiber-optic mother-baby scope systems:<\/strong> Qualify &#8211; any system introducing a small-caliber scope through the duodenoscope working channel<\/li>\n\n\n\n<li><strong>Other digital choledochoscopes:<\/strong> Qualify &#8211; provided the operative note documents direct ductal visualization<\/li>\n\n\n\n<li><strong>Fluoroscopy alone:<\/strong> Does not qualify &#8211; this is the baseline ERCP imaging method, already included in the primary code<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, the clinical documentation must confirm that direct visualization occurred and name the system used. Payers may request operative notes on audit, so vague documentation (&#8220;scope was advanced&#8221;) creates unnecessary denial risk.<\/p>\n\n\n\n<h2 id=\"h-which-modifiers-apply-to-43273\" class=\"wp-block-heading\">Which modifiers apply to 43273<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As an add-on code, CPT Code 43273 has a limited modifier profile. Consequently, several modifiers that apply to standalone procedures do not apply here. As a result, the wrong modifier is one of the faster ways to trigger an edit or a denial.<\/p>\n\n\n\n<table style=\"width:100%;border-collapse:separate;border-spacing:0;border-radius:12px;overflow:hidden;font-size:15px;line-height:1.5;margin:1.5em 0 2em;box-shadow:0 2px 12px rgba(0,0,0,0.08)\">\n<thead>\n<tr>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Modifier<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Name<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">When to Use with 43273<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">59<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Distinct procedural service<\/td>\n<td style=\"padding:12px 16px;color:#374151\">When payer edits bundle 43273 with another add-on; signals a separately identifiable service<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">XU<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Unusual non-overlapping service<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Many payers prefer this over modifier 59; it clarifies that scope introduction was a separate service<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">51<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Multiple procedures<\/td>\n<td style=\"padding:12px 16px;color:#374151\"><strong>Do not use<\/strong> &#8211; add-on codes are exempt from the multiple procedure reduction rule; modifier 51 is inappropriate here<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">80<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Assistant surgeon<\/td>\n<td style=\"padding:12px 16px;color:#374151\">When a second physician provided assistant surgeon services during the cholangioscopy portion; verify payer-specific coverage<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">Check <a href=\"https:\/\/www.aapc.com\/codes\/cpt-codes-range\/\" target=\"_blank\" rel=\"nofollow noopener\">AAPC Codify<\/a> for the current NCCI Procedure-to-Procedure edits that affect 43273 pairings.

In addition, rates vary by site of service (facility vs. non-facility), and the Geographic Practice Cost Index (GPCI) adjusts them for regional cost differences.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gastroenterologists almost always perform 43273 in a hospital outpatient department or an ambulatory surgical center. The facility rate is therefore the figure that matters for most gastroenterology practices. By contrast, non-facility rates apply only in the rare cases where the procedure happens in a physician office.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Verify current dollar amounts against the <a href=\"https:\/\/www.cms.gov\/medicare\/physician-fee-schedule\/search\/overview\" target=\"_blank\" rel=\"nofollow noopener\">CMS fee schedule tool<\/a>, since CMS updates rates each January.

Instead, auditors look for evidence that the physician introduced a separate small-caliber scope and that direct ductal visualization occurred.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keeping that record inside <a href=\"https:\/\/pabau.com\/blog\/hipaa-compliance-for-medical-offices\/\">HIPAA-compliant documentation<\/a> protects the claim and the patient. <a href=\"https:\/\/pabau.com\/blog\/medical-forms-at-your-healthcare-practice\/\">Structured medical forms<\/a> also reduce inconsistency between providers in the same practice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The operative note should include all of the following elements:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Statement of direct visualization:<\/strong> Confirm that the physician performed endoscopic pancreatoscopy or cholangioscopy (not just fluoroscopy)<\/li>\n\n\n\n<li><strong>Scope identification:<\/strong> Name the system used (e.g., SpyGlass DS, fiber-optic choledochoscope) and confirm the physician introduced it through the duodenoscope working channel<\/li>\n\n\n\n<li><strong>Duct(s) visualized:<\/strong> Specify whether the physician visualized the bile duct, the pancreatic duct, or both<\/li>\n\n\n\n<li><strong>Findings:<\/strong> Document what the physician observed (stone burden, stricture characteristics, mucosal appearance, tumor involvement)<\/li>\n\n\n\n<li><strong>Medical necessity statement:<\/strong> Explain why the case required direct visualization beyond standard fluoroscopy (e.g., indeterminate stricture, stone completeness confirmation, targeted biopsy guidance)<\/li>\n\n\n\n<li><strong>Separate service notation:<\/strong> If billing multiple add-on codes, confirm each service was distinct and not duplicative<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid generic language like &#8220;scope was advanced into the duct.&#8221; This does not confirm direct visualization occurred, nor does it distinguish cholangioscopy from routine ERCP cannulation. As a result, specificity in the operative note is the single most effective audit defense.<\/p>\n\n\n\n<h2 id=\"h-related-ercp-cpt-codes\" class=\"wp-block-heading\">Related ERCP CPT codes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT Code 43273 sits within the ERCP code family spanning 43260 through 43278. Billing staff often need the whole suite for a single session, since more than one add-on code can apply to one encounter. In turn, knowing which codes are primary and which are add-on reduces unbundling risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Surgical gastrointestinal codes such as <a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-43361\/\">43361<\/a> and <a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-43653\/\">43653<\/a> sit outside the ERCP family altogether. Consequently, they are never valid primary codes for 43273.<\/p>\n\n\n\n<table style=\"width:100%;border-collapse:separate;border-spacing:0;border-radius:12px;overflow:hidden;font-size:15px;line-height:1.5;margin:1.5em 0 2em;box-shadow:0 2px 12px rgba(0,0,0,0.08)\">\n<thead>\n<tr>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">CPT Code<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Type<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Descriptor (abbreviated)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43260<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Diagnostic ERCP<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43261<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with biopsy<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43262<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with sphincterotomy<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43264<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with calculi removal<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43265<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with calculi destruction<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43270<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with ablation of tumor\/polyp\/lesion<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43273<\/td>\n<td style=\"padding:12px 16px;color:#374151\"><strong>Add-on (+)<\/strong><\/td>\n<td style=\"padding:12px 16px;color:#374151\"><strong>Endoscopic cannulation of papilla with direct visualization of pancreatic\/common bile duct(s)<\/strong><\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43274<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with stent placement, biliary or pancreatic duct<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43275<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with stent or foreign body removal<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43276<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with stent replacement<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43277<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with dilation of stricture(s)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">43278<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ERCP with ablation including pre- and post-dilation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">When one ERCP session includes several services, report the primary code that matches the primary service and add 43273 for the cholangioscopy component. For example, a sphincterotomy with stone removal and cholangioscopy is the classic example. In practice, <a href=\"https:\/\/pabau.com\/blog\/ehr-integration\/\">EHR integration<\/a> helps capture every code performed at the point of care rather than after the visit.<\/p>\n\n\n\n<h2 id=\"h-common-billing-errors-and-how-to-avoid-them\" class=\"wp-block-heading\">Common billing errors and how to avoid them<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Seven denial patterns account for most rejected 43273 claim lines. In turn, each one below carries its direct fix.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Billing 43273 without a primary ERCP code:<\/strong> Automatic denial, because payer edit logic hard-codes the add-on designation. Always pair with 43260-43278.<\/li>\n\n\n\n<li><strong>Applying modifier 51:<\/strong> Incorrect for add-on codes. Modifier 51 triggers the multiple procedure payment reduction, but add-on codes are exempt. Therefore, remove modifier 51 from any 43273 claim line.<\/li>\n\n\n\n<li><strong>Restricting use to SpyGlass cases only:<\/strong> Causes under-billing, since any qualified direct visualization system triggers the code. Instead, confirm documentation names the scope, not just the brand.<\/li>\n\n\n\n<li><strong>Vague operative note language:<\/strong> &#8220;Scope was advanced&#8221; or &#8220;cholangioscopy was attempted&#8221; does not confirm that direct visualization occurred. Instead, auditors look for explicit statements of what the endoscopist saw.<\/li>\n\n\n\n<li><strong>Missing medical necessity documentation:<\/strong> Documenting the procedure without explaining why the case required direct visualization beyond fluoroscopy gives payers grounds for denial. Instead, the operative note should state the clinical question that only cholangioscopy could answer.<\/li>\n\n\n\n<li><strong>Not verifying NCCI edits annually:<\/strong> CMS updates NCCI edit tables quarterly, so a code pairing that was clean last year may carry a bundling edit this year. Therefore, check NCCI edits for the current quarter before assuming a pairing is valid.<\/li>\n\n\n\n<li><strong>Using the wrong site-of-service code:<\/strong> Facility and non-facility rates differ, so submitting with the wrong place-of-service indicator affects allowed amounts and can trigger edits when the billed site does not match the facility record.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Practices that flag 43273 for review whenever the operative note documents a cholangioscopy scope see fewer post-submission corrections. In practice, practice management software like Pabau supports that kind of procedure-level tracking through its <a href=\"https:\/\/pabau.com\/features\/claims-management-software\/\">claims management software<\/a>. Ultimately, tying the code to the clinical note at the point of care is the most reliable way to cut these errors.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.pabau.com\/cdn\/attachments\/pulse\/content-engine\/billing_codes\/cpt-code-43273\/fully-integrated-with-pabau-billing.webp\" alt=\"Fully Integrated with Pabau Billing\"\/><figcaption class=\"wp-element-caption\"><em>Pabau posts each coded procedure straight to the invoice, so billers never have to add a 43273 line by hand later.<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:35px;width:800px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n        <div id=\"pro_tip\">\n            <div class=\"img\">\n                <svg width=\"42\" height=\"42\" viewBox=\"0 0 42 42\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                        d=\"M12.6383 19.5238C12.6632 21.2071 12.8734 22.9926 12.0685 24.5523C11.0341 26.8917 8.45076 28.169 7.56292 30.5918C6.63082 33.1061 7.19505 36.185 9.31371 37.9786C10.929 39.5678 13.4183 39.9873 15.6061 39.5463C17.4592 39.073 19.1049 37.8388 19.9706 36.1608C20.781 34.7141 20.7866 32.9904 20.5293 31.3985C20.1006 29.3092 18.3775 27.8705 16.9807 26.362C14.8814 24.1005 14.6684 20.6854 15.595 17.8915C16.4331 15.4768 19.0026 14.2344 20.0425 11.9461C20.7202 10.6769 20.7506 9.20327 20.6068 7.81304C20.1864 5.40098 18.3139 3.23631 15.8716 2.56674C13.9742 2.03969 11.8224 2.30052 10.1739 3.37614C8.70522 4.34688 7.5878 5.86618 7.28356 7.58178C6.76081 9.82981 7.53525 12.2822 9.20307 13.9118C10.7658 15.4741 12.4806 17.2273 12.6383 19.5238Z\"\n                        fill=\"#2BADD4\" \/>\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                        d=\"M22.7048 19.8387C22.6822 22.3279 24.4507 24.6234 26.7493 25.4682C28.0531 25.961 29.4725 25.9183 30.7989 25.5487C32.0575 24.9955 33.301 24.2237 34.0069 23.0092C34.8384 21.5811 35.2982 19.8286 34.7832 18.2094C34.3611 16.2507 32.8739 14.6541 31.0275 13.9426C28.6736 12.9595 25.8073 13.7942 24.1719 15.7001C23.2022 16.8366 22.6143 18.3326 22.7048 19.8387Z\"\n                        fill=\"#2BADD4\" \/>\n                <\/svg>\n            <\/div>\n            <div class=\"text\">\n                <h3>Pro Tip<\/h3>\n                <p>Run a quarterly audit of all claims where the practice billed a primary ERCP code but not 43273. Then, pull the operative notes for those encounters and confirm whether a separate scope for direct visualization was actually used.

First, the endoscopist dictates the operative note, and days later a coder reads it and guesses whether the physician used a separate scope. Consequently, that delay is where 43273 quietly disappears from the claim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practice management software like Pabau closes that loop by keeping the code and the note in one record. As a result, the scope used, the ducts visualized, and the medical necessity statement sit against the same encounter as the billed line. Billing staff can see the evidence for the add-on code before the claim leaves the practice. Consequently, fewer lines get dropped, and fewer get queried on audit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same workflow carries across specialties, from <a href=\"https:\/\/pabau.com\/industry\/gp-clinic-software\/\">general practice software<\/a> through to <a href=\"https:\/\/pabau.com\/industry\/functional-medicine-software\/\">functional medicine software<\/a>. Every Pabau subscription includes every feature, so procedure-level coding is not something a practice pays extra to unlock.<\/p>\n\n\n        <div id=\"book_a_demo\">\n            <div class=\"left-side\">\n                <div class=\"logo\">\n                    <img decoding=\"async\"\n                        src=\"https:\/\/pabau.com\/wp-content\/uploads\/2026\/01\/Logo.svg\"\n                        alt=\"Logo\"\n                        loading=\"lazy\"\n                    \/>\n                <\/div>\n\n                <h3 class=\"heading\">\n                    Stop losing revenue on ERCP add-on claims                <\/h3>\n\n                <p class=\"description\">\n                    Pabau&#8217;s claims management software lets gastroenterology billing teams tag codes like 43273 at the point of care.

Specifically, three things decide the claim: a valid primary ERCP code, an operative note that states what the endoscopist saw, and a modifier set that leaves 51 off the line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fix the note template first. A note that names the scope and the ducts visualized answers the auditor and tells the coder what to bill. As a result, that single change removes most of the guesswork. Finally, reviewing NCCI edits each quarter handles the rest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off worth remembering is that under-billing this code costs as much as over-billing it, and never shows up in a denial report.

43273?<\/h3> <p class=\"schema-faq-answer\">CPT Code 43273 is an add-on code for endoscopic cannulation of the papilla with direct visualization of the pancreatic or common bile duct. Specifically, the endoscopist passes a small-caliber endoscope through the duodenoscope working channel to see inside the duct. As a result, it must always be reported alongside a primary ERCP code from the 43260-43278 family.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786434605615\"><h3 class=\"schema-faq-question\">Is CPT 43273 for SpyGlass only?<\/h3> <p class=\"schema-faq-answer\">No. CPT 43273 applies to any technology that achieves direct endoscopic visualization of the bile or pancreatic duct. SpyGlass DS is the most commonly used system, but fiber-optic mother-baby scope systems and other digital choledochoscopes also qualify. The operative note must document direct visualization and name the scope used, but the manufacturer is not a billing criterion.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786434605619\"><h3 class=\"schema-faq-question\">Can CPT 43273 be billed for endoscopic pancreatoscopy as well as cholangioscopy?<\/h3> <p class=\"schema-faq-answer\">Yes. The descriptor covers direct visualization of the pancreatic duct, the common bile duct, or both. Report the code once per ERCP session, even when the physician examined both ducts on separate scope passes. In addition, document each duct visualization separately in the operative note and confirm your payer policy before submission.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786434605621\"><h3 class=\"schema-faq-question\">What is the Medicare reimbursement rate for CPT 43273?<\/h3> <p class=\"schema-faq-answer\">CMS updates Medicare rates for CPT 43273 annually in the Medicare Physician Fee Schedule. The facility rate (applicable in ASC and hospital outpatient settings) differs from the non-facility rate. Rates also vary by geographic region via the GPCI adjustment. For current verified dollar amounts, use the CMS Physician Fee Schedule lookup tool at cms.gov or the FastRVU 2026 RVU calculator for location-adjusted figures.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>CPT Code 43273 is an add-on code for endoscopic cannulation of the papilla with direct visualization of the pancreatic or common bile duct.
