It sits in the \u00abFracture and\/or Dislocation Procedures on the Head\u00bb section of the CPT codebook. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That section covers the 213xx range for nasal bone and septal injuries, including its open treatment counterpart, <a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-21336\/\">21336<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The nasal septum is the cartilaginous and bony wall that divides the nasal cavity in two. When it fractures, closed treatment covers any approach that repositions or manages the fracture without an incision through the skin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two elements define this code. The treatment must be closed, with no open incision. Stabilization may or may not be used, and that second element is where billers misread the code.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The phrase \u00abwith or without stabilization\u00bb does not let the provider skip documenting it. If stabilization was used, the note records the type and the placement. If it was not used, the record should say so explicitly. That line is what supports the code when a payer reviews the claim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The AMA CPT code set applies 21337 to the nasal septum rather than the nasal bones. That anatomical distinction is the main differentiator between this code and the nasal bone fracture codes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Clinical context: Nasal septal fracture and closed treatment<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Nasal septal fractures usually follow blunt facial trauma. Sports injuries, falls, motor vehicle accidents, and assaults are the most common mechanisms. The code therefore turns up in ENT, urgent care, and <a href=\"https:\/\/pabau.com\/industry\/sports-medicine-software\/\">sports medicine practices<\/a>. The septum can fracture alone or alongside the nasal bones, which changes code selection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Closed treatment of a nasal septal fracture may involve manual reduction of the displaced septum. It can also mean intranasal splints or packing, or observation alone where the fracture is non-displaced. The stabilization component, when used, typically means splinting or packing to hold the septum in position during healing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Timing matters for billing. Most closed nasal fractures are treated within 7 to 10 days of injury, before edema and scar tissue complicate reduction. Documentation should note the date of injury next to the date of treatment. That pairing establishes medical necessity and shows the treatment fell inside the payer&#8217;s window.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ENT and <a href=\"https:\/\/pabau.com\/industry\/plastic-surgery-emr\/\">plastic surgery practices<\/a> treating nasal trauma at volume should standardize the intake note. A template covering mechanism, timing, and treatment details keeps them from going missing at the point of care.<\/p>\n\n\n\n<h2 id=\"h-medicare-reimbursement-and-the-year-fee-schedule\" class=\"wp-block-heading\">Medicare reimbursement and the 2026 fee schedule<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare reimbursement for CPT code 21337 runs on the three-component Relative Value Unit (RVU) structure. That means work RVU, practice expense RVU, and malpractice RVU. Each component is multiplied by the Geographic Practice Cost Index (GPCI) value for the provider&#8217;s locality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The adjusted components are then summed and multiplied by the 2026 conversion factor to produce the payment. Facility rates apply when the procedure happens in a hospital or ambulatory surgical center (ASC). Non-facility rates apply when it happens in the practice&#8217;s own office.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use the <a href=\"https:\/\/www.cms.gov\/medicare\/physician-fee-schedule\/search\/overview\" target=\"_blank\" rel=\"nofollow noopener\">CMS fee schedule lookup<\/a> for the exact 2026 rate in your locality.

Missing any one of them is sufficient grounds for denial or recoupment. The encounter note, operative report, or clinical record should address each element clearly.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mechanism of injury:<\/strong> Document how the fracture occurred (blunt trauma, fall, sports impact). This establishes medical necessity and connects the claim to the ICD-10 diagnosis code.<\/li>\n\n\n\n<li><strong>Physical examination findings:<\/strong> Include nasal inspection findings, septal deviation or displacement, and the presence of epistaxis, edema, or crepitus. After a high-energy mechanism, record <a href=\"https:\/\/pabau.com\/blog\/neurological-vital-signs\/\">neurological vital signs<\/a> too, since the same visit screens for head injury. Vague notes (\u00abnasal trauma seen\u00bb) are not sufficient.<\/li>\n\n\n\n<li><strong>Confirmation of closed approach:<\/strong> The record must confirm that treatment was performed without open surgical incision. This distinguishes CPT code 21337 from open treatment codes in the same series.<\/li>\n\n\n\n<li><strong>Stabilization details (if performed):<\/strong> If intranasal splints, packing, or external splinting was applied, document the type used, the side(s), and the duration planned. If no stabilization was used, document that the fracture did not require it or that the patient could not tolerate it.<\/li>\n\n\n\n<li><strong>Medical necessity statement:<\/strong> Some commercial payers and Medicare Advantage plans require an explicit statement linking the procedure to the diagnosis. A sentence confirming that closed treatment was indicated for a displaced\/unstable nasal septal fracture satisfies this requirement.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Practices handling nasal trauma can build the five elements into a documentation template. The template prompts the provider to capture each one during the encounter, rather than during a payer audit. <a href=\"https:\/\/pabau.com\/features\/patient-intake-software\/\">Digital intake forms<\/a> built around the same five elements cut incomplete charting before claims go out.<\/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-21337\/digital-forms.webp\" alt=\"Pabau digital intake form on a tablet\"\/><figcaption class=\"wp-element-caption\"><em>Pabau&#8217;s digital forms capture the injury date and mechanism at check-in, so the 21337 claim carries its medical necessity detail.<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:35px;width:800px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Related CPT codes in the 213xx family<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The 213xx series covers nasal bone and septal fractures across several treatment types.

Procedure-to-procedure edits apply across the 213xx family, so some pairs cannot be billed on the same claim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One code in this family no longer exists. The AMA deleted 21310 effective January 1, 2022, so a closed nasal bone fracture treated without manipulation is billed with an E\/M code instead. Neighboring facial fracture codes such as <a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-21343\/\">21343<\/a> follow the same open-versus-closed logic.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Global period and post-operative billing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT code 21337 carries a 90-day global surgical period under the Medicare Physician Fee Schedule. Routine follow-up care inside those 90 days is bundled into the original payment. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That includes splint or packing removal, wound checks, and routine visits related to the treated fracture. Billing those encounters separately is a frequent source of duplicate-service denials.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some post-operative services stay separately payable when the record supports them. Modifier -24 covers an unrelated evaluation and management service during the global period. Modifier -79 covers an unrelated procedure by the same physician. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use modifier -58 for a staged or more extensive procedure, and -78 for an unplanned return to the operating room.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Record the global period start date in the chart at the time of treatment. Front-desk and billing staff can then tell which follow-up visits are already paid for, and which qualify for a separate claim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/pabau.com\/templates\/patient-discharge-form\/\">discharge instructions<\/a> handed to the patient can carry the planned splint removal date. That keeps the follow-up visit inside the global window, where it belongs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common billing errors and denial risks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Claims for nasal fracture and septal fracture treatment generate a specific pattern of denials. Most are preventable with the right documentation habits and a clear code selection process. The errors below show up most often in payer audit findings across the 213xx family.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Using an open treatment code (21336) for a closed procedure:<\/strong> This is upcoding. If the procedure did not involve a surgical incision, CPT code 21337 is the correct code. Upcoding exposes the practice to Medicare audits and recoupment.<\/li>\n\n\n\n<li><strong>Using a nasal bone code when the septum was treated:<\/strong> Code 21315 or 21320 is wrong when the septum is the primary structure. Anatomy-specific selection needs imaging or exam documentation to support the distinction.<\/li>\n\n\n\n<li><strong>Missing stabilization documentation:<\/strong> Stabilization that was performed but not documented leaves the claim open to denial. The payer&#8217;s position is that the procedure as documented does not support the code billed. If stabilization was not performed, document that explicitly.<\/li>\n\n\n\n<li><strong>Wrong ICD-10 encounter character:<\/strong> Using S02.2XXD (subsequent encounter) for the initial active treatment is one of the most consistent medical necessity denial triggers.<\/li>\n\n\n\n<li><strong>Global period violations:<\/strong> Billing routine follow-up visits inside the 90-day global period produces bundled-service denials. The section above lists the modifiers that make a post-operative service separately payable.<\/li>\n\n\n\n<li><strong>Modifier -25 missing on a same-day E\/M:<\/strong> An E\/M service billed on the same day as CPT code 21337 needs modifier -25. The modifier flags a significant, separately identifiable service.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Practices handling several nasal trauma cases a week benefit from a pre-submission review. It checks each of these points before claims leave the <a href=\"https:\/\/pabau.com\/blog\/practice-management-software\/\">practice management system<\/a>. Tracking denials by reason code then shows which error keeps recurring, so the team can fix that one first.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Payer policies and prior authorization<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare does not typically require prior authorization for CPT code 21337, but commercial payers and Medicare Advantage plans vary widely. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some plans require authorization for any surgical procedure code in the 213xx range, even when the treatment itself is non-surgical. Verify the payer&#8217;s authorization rules before any elective or scheduled treatment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Local Coverage Determinations (LCDs) issued by Medicare Administrative Contractors (MACs) may impose additional medical necessity criteria. These typically require documentation confirming symptomatic fracture displacement, failed conservative management where applicable, or specific clinical findings that justify active treatment rather than observation. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Review the applicable MAC&#8217;s LCD for nasal procedures to confirm your documentation meets the stated criteria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Commercial payer policies differ from Medicare in ways that matter for CPT code 21337. Bilateral procedures with modifier -50 may need separate authorization. Some insurers apply cosmetic procedure exclusions broadly to nasal work, and deny claims that are clearly reconstructive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In those cases, attach a letter of medical necessity to the authorization request. Citing imaging findings and functional impairment, such as nasal obstruction, usually strengthens the appeal. Practices that keep <a href=\"https:\/\/pabau.com\/blog\/hipaa-compliance-software\/\">HIPAA-compliant documentation<\/a> workflows can pre-build these letters and link them to the code in their billing system.<\/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>Request a written policy document from commercial payers that frequently deny CPT code 21337 claims. Some payers categorize nasal fracture treatment under a cosmetic procedure exclusion by default. Having the written policy in hand before submission lets your team address the exclusion up front. Handling it in the prior authorization request beats fighting it in appeals.<\/p>\n            <\/div>\n        <\/div>\n    \n\n\n<h2 class=\"wp-block-heading\">How Pabau supports nasal fracture billing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">ENT and facial plastic surgery practices billing the 213xx family usually lose money on documentation rather than on code choice. The five required elements have to reach the note during the encounter itself. Reconstructing them weeks later, after a payer has denied the claim, rarely succeeds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practice management software like Pabau puts those elements in front of the provider at the point of care. Clinical note templates prompt for mechanism of injury, exam findings, treatment approach, and stabilization details. Digital intake forms capture the injury date, which is what establishes timely treatment for the payer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the billing side, claims management tools flag missing modifiers before submission and track denials by CPT code. Billing leads can see whether 21337 denials cluster around stabilization documentation, encounter characters, or cosmetic exclusions. That turns a recurring write-off into a specific fix your team can make this month.<\/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                    Cut denials across the 213xx fracture codes                <\/h3>\n\n                <p class=\"description\">\n                    Pabau prompts for the documentation each 213xx claim needs, then tracks denials by code.

class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1786626528717\"><h3 class=\"schema-faq-question\">What is CPT code 21337?<\/h3> <p class=\"schema-faq-answer\">CPT code 21337 is the procedure code for closed treatment of nasal septal fracture, with or without stabilization. It covers non-surgical management of a fractured nasal septum, the cartilaginous and bony wall dividing the nasal cavity. That includes manual reduction and the optional application of intranasal splints or packing. It is listed in the Fracture and\/or Dislocation Procedures on the Head section of the AMA CPT codebook.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626528718\"><h3 class=\"schema-faq-question\">What does \u00abwith or without stabilization\u00bb mean for billing CPT 21337?<\/h3> <p class=\"schema-faq-answer\">The phrase means the code is billable whether or not stabilization (splinting or packing) was performed. It does not remove the documentation requirement. If stabilization was used, the operative note must describe the type and placement. If it was not used, the record should state that explicitly so payers cannot question whether the service matches the code.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626528719\"><h3 class=\"schema-faq-question\">What modifiers apply to CPT code 21337?<\/h3> <p class=\"schema-faq-answer\">The most common modifiers are -50 (bilateral procedure), -RT\/-LT (right or left side laterality), -52 (reduced services), and -22 (increased procedural complexity). Modifier -25 applies to any same-day evaluation and management service billed alongside CPT code 21337. Each modifier requires supporting documentation in the clinical record.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626528720\"><h3 class=\"schema-faq-question\">What is the Medicare reimbursement rate for CPT code 21337?<\/h3> <p class=\"schema-faq-answer\">The exact 2026 Medicare rate depends on the provider&#8217;s geographic locality, facility vs. non-facility setting, and the annual conversion factor. Non-facility rates are higher than facility rates because the practice absorbs overhead. Use the CMS Physician Fee Schedule lookup tool to retrieve current locality-specific payment amounts rather than relying on third-party estimates.<\/p> <\/div> <\/div>\n\n\n\n<h3 id=\"h-icd-10-coding-code-selection-and-documentation\" class=\"wp-block-heading\">ICD-10 coding, code selection, and documentation<\/h3>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1786626528721\"><h3 class=\"schema-faq-question\">What ICD-10 codes are used with CPT 21337?<\/h3> <p class=\"schema-faq-answer\">S02.2XXA (fracture of nasal bones, initial encounter for closed fracture) is the primary ICD-10-CM code paired with CPT 21337 for the initial active treatment. S02.2XXD applies to subsequent follow-up encounters, and S02.2XXS applies to sequela. Using S02.2XXD for an initial treatment encounter is a common and avoidable medical necessity denial trigger.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626528722\"><h3 class=\"schema-faq-question\">How does CPT 21337 differ from CPT 21315 or 21336?<\/h3> <p class=\"schema-faq-answer\">CPT 21315 covers closed treatment of nasal bone fracture with manipulation but without stabilization, and it targets the nasal bones rather than the septum. CPT 21336 covers open treatment of nasal septal fracture, meaning a surgical incision was made. CPT 21337 is the closed (non-surgical) counterpart to 21336, and the septal counterpart to 21315 and 21320. Code selection hinges on anatomy (septum vs. nasal bone) and approach (open vs. closed).<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626528723\"><h3 class=\"schema-faq-question\">What documentation is required to bill CPT code 21337?<\/h3> <p class=\"schema-faq-answer\">Five elements are required. Document the mechanism of injury and the exam findings that confirm the septal fracture. Confirm that treatment was closed, with no surgical incision. Add stabilization details if splinting or packing was applied. Close with a medical necessity statement linking the procedure to the diagnosis. Missing stabilization documentation and using the wrong ICD-10 encounter character are the two most common denial triggers.<\/p> <\/div> <\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>CPT code 21337 covers closed treatment of nasal septal fracture, with or without stabilization.
