Procedures that do not map to a more specific eye code \u2014 including strabismus repair, which involves the extraocular muscles rather than the vitreous or retina \u2014 are billed under 00140, not 00145.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a procedure has its own designated anesthesia code within the family (00142 for lens surgery, 00144 for corneal transplant, 00145 for vitreoretinal surgery, 00147 for iridectomy, 00148 for ophthalmoscopy), that more specific code takes precedence over the 00140 NOS code.<\/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\">Value<\/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\">00145<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Long description<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia for procedures on eye; vitreoretinal surgery<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Short description<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia, eye vitreoretinal surgery<\/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\">Anesthesia for Procedures on the Head (00100-00222)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Base units (ASA RVG)<\/td>\n<td style=\"padding:12px 16px;color:#374151\">6 units (verify against current ASA Relative Value Guide)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Code type<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Standalone (not add-on)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Maintained by<\/td>\n<td style=\"padding:12px 16px;color:#374151\">American Medical Association (AMA)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<h2 id=\"h-anesthesia-base-units-and-the-billing-formula-for-cpt-00145\" class=\"wp-block-heading\">Anesthesia base units and the billing formula for CPT 00145<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT Code 00145 carries 6 base units according to the American Society of Anesthesiologists (ASA) Relative Value Guide (RVG). Base units reflect the inherent complexity of providing anesthesia for a given procedure type, independent of how long the case runs. A higher base unit value signals greater clinical complexity and typically correlates with a higher reimbursement floor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anesthesia billing does not work like standard CPT billing. Rather than a flat fee per code, the payment calculation combines three components. The standard formula, confirmed by both the ASA and CMS, is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Total Billable Units = Base Units + Time Units + Modifying Units<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That total is then multiplied by the applicable conversion factor to arrive at a dollar amount. The conversion factor varies by payer. Medicare publishes its own anesthesia conversion factor annually, and commercial payers set their own rates separately.<\/p>\n\n\n\n<h3 id=\"h-how-time-units-are-calculated\" class=\"wp-block-heading\">How time units are calculated<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Time units are added to the base units to reflect the duration of anesthesia care. The standard convention is 1 time unit per 15 minutes of anesthesia time, though some payers use a different interval. Anesthesia time begins when the anesthesia provider starts preparing the patient and ends when the provider is no longer in personal attendance.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Base units:<\/strong> 6 (assigned to CPT 00145 by the ASA RVG)<\/li>\n\n\n\n<li><strong>Time units:<\/strong> 1 unit per 15 minutes (confirm interval with individual payers)<\/li>\n\n\n\n<li><strong>Modifying units:<\/strong> Physical status and qualifying circumstance add-on units recognized by ASA-based commercial payers (see below; Medicare treats these differently)<\/li>\n\n\n\n<li><strong>Conversion factor:<\/strong> Published annually by CMS for Medicare; negotiated separately by commercial payers<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A 60-minute pars plana vitrectomy under general anesthesia, with no physical status modifiers beyond P2, would yield: 6 (base) + 4 (time, for 60 minutes at 1 unit per 15 min) = 10 total units before applying the conversion factor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For payers that recognize modifying units, physical status or qualifying circumstance add-ons would increase this figure further; Medicare does not add either type of unit (see the Medicare reimbursement section below).<\/p>\n\n\n\n<h2 id=\"h-modifiers-for-cpt-code-00145\" class=\"wp-block-heading\">Modifiers for CPT Code 00145<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Anesthesia modifier selection is one of the most error-prone areas in ophthalmic anesthesia billing. CPT Code 00145 requires at least one practitioner-type modifier on every claim. Missing or incorrect modifiers are a leading cause of claim denials and audit flags for this code type.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Three modifier categories apply: practitioner-type modifiers, physical status modifiers, and qualifying circumstance add-on codes. All three may appear on a single claim, though Medicare only recognizes the first category for payment purposes.<\/p>\n\n\n\n<h3 id=\"h-practitioner-type-modifiers\" class=\"wp-block-heading\">Practitioner-type modifiers<\/h3>\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\">Description<\/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<\/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\">AA<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia services performed personally by anesthesiologist<\/td>\n<td style=\"padding:12px 16px;color:#374151\">MD\/DO anesthesiologist personally performs all anesthesia care<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">QX<\/td>\n<td style=\"padding:12px 16px;color:#374151\">CRNA service, with medical direction by a physician<\/td>\n<td style=\"padding:12px 16px;color:#374151\">CRNA operating under an anesthesiologist&rsquo;s medical direction (1:4 rule)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">QY<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Medical direction of one CRNA by an anesthesiologist<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Single CRNA medically directed by one anesthesiologist<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">QZ<\/td>\n<td style=\"padding:12px 16px;color:#374151\">CRNA service, without medical direction by a physician<\/td>\n<td style=\"padding:12px 16px;color:#374151\">CRNA practicing independently without physician medical direction<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">QK<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Medical direction of two, three, or four concurrent anesthesia procedures<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesiologist directing 2-4 CRNAs concurrently (paired with QX)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">AD<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Medical supervision of more than four concurrent anesthesia procedures<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesiologist supervising 5+ concurrent cases (reduced payment)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare&rsquo;s medical direction rules for the AA and QK\/QX modifier pair are strictly defined by CMS.

Documenting right, left, or bilateral where applicable, and using the most specific code available in the record, reduces the risk of a medical necessity denial. Consistent use of structured medical forms for healthcare practices at intake reduces the risk of defaulting to unspecified codes at billing time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A quick note on strabismus: because strabismus repair involves the extraocular muscles rather than the vitreous or retina, it is not billed under 00145. It is coded to CPT 00140 (the NOS code) and typically pairs with a strabismus diagnosis such as H50.9 (unspecified strabismus), H50.00 (esotropia, unspecified), or a laterality-specific code such as H50.411 (cyclotropia, right eye).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A claim for 00145 submitted with a strabismus-only diagnosis and no vitreoretinal procedure documented should be expected to draw a medical necessity denial. The same logic applies to eyelid trauma: a diagnosis such as S01.129S belongs with an eyelid repair code, not with 00145.<\/p>\n\n\n\n<h2 id=\"h-related-cpt-codes-for-ophthalmic-anesthesia\" class=\"wp-block-heading\">Related CPT codes for ophthalmic anesthesia<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT Code 00145 is one of six anesthesia codes in the eye-procedure family.

Billing a cataract (lens) case under 00145 instead of 00142 \u2014 or vice versa \u2014 creates a base unit mismatch against the documented procedure, which is exactly the kind of discrepancy payer systems are built to flag.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a full anesthesia code list, the <a href=\"https:\/\/www.ama-assn.org\/practice-management\/cpt\/cpt-coding-resources\" target=\"_blank\" rel=\"nofollow noopener\">AMA CPT coding resources<\/a> page provides official descriptions and section guidance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same specificity principle applies elsewhere in the CPT anesthesia section: CPT 00212, for intracranial procedures, follows an identical base-unit logic within the same Head subsection.<\/p>\n\n\n\n<h2 id=\"h-documentation-requirements-for-billing-cpt-code-00145\" class=\"wp-block-heading\">Documentation requirements for billing CPT Code 00145<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Clean claims for CPT Code 00145 depend on a complete anesthesia record. Payers use the anesthesia record to verify time units, confirm modifier eligibility, and audit physical status classification. Missing or incomplete documentation is the fastest route to a post-payment audit request.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Following HIPAA-compliant documentation practices. Beyond HIPAA, the specific elements required for anesthesia billing include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pre-anesthesia evaluation:<\/strong> Documented assessment of the patient&rsquo;s physical status (P1-P6 classification with clinical justification)<\/li>\n\n\n\n<li><strong>Anesthesia start and stop times:<\/strong> Exact times recorded to support time unit calculation; required on the claim and in the medical record<\/li>\n\n\n\n<li><strong>Intraoperative anesthesia record:<\/strong> Vital signs, agents used, continuous monitoring notes throughout the case<\/li>\n\n\n\n<li><strong>Practitioner-type documentation:<\/strong> Record establishing whether the case was personally performed (AA), medically directed (QK\/QX), or independently CRNA-managed (QZ)<\/li>\n\n\n\n<li><strong>Qualifying circumstance justification:<\/strong> If 99100, 99116, 99135, or 99140 is billed to a commercial payer that recognizes it, the medical record must support the specific circumstance claimed<\/li>\n\n\n\n<li><strong>Post-anesthesia note:<\/strong> Documentation of patient recovery status and handoff to recovery personnel<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Practices using digital anesthesia consent forms cut down on missing pre-anesthesia documentation at the point of capture, before the case begins. Pre-populated physical status questions and timestamp fields mean the record is complete before the patient leaves intake.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This directly reduces the incidence of modifier-documentation mismatches that trigger post-payment audits. The same layered documentation burden applies to other anesthesia-heavy specialties.<\/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-00145\/customizable-consent-and-intake-forms.webp\" alt=\"Customizable consent and intake forms\"\/><figcaption class=\"wp-element-caption\"><em>Customizable consent and intake forms<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:20px\" 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>Build a pre-billing checklist specific to CPT Code 00145: anesthesia start\/stop times recorded, physical status modifier documented with clinical justification, practitioner-type modifier confirmed against the operative log, and any qualifying circumstance code supported by a documented indication for payers that recognize it.

CPT Code 00145 carries 6 base units, sits alongside \u2014 but should never be confused with \u2014 the NOS catch-all code 00140, and its multiple modifier categories and time-unit calculation leave little room for guesswork.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Misreporting the base code, missing a modifier, miscounting time units, or failing to document physical status classification can flip a clean claim into a denial or an audit trigger.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pabau&rsquo;s claims management tools are built for exactly this kind of structured, rule-heavy billing environment. Modifier validation, automated time unit tracking, and pre-submission audit trails reduce the manual checking burden so billing teams can focus on accuracy rather than catching errors after the fact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To see how it works in practice, <a href=\"https:\/\/pabau.com\/book-demo\/\">book a demo<\/a> and walk through an anesthesia billing workflow with

wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1784874568811\"><h3 class=\"schema-faq-question\">What is CPT Code 00145 used for?<\/h3> <p class=\"schema-faq-answer\">CPT Code 00145 is the anesthesia procedure code for vitreoretinal surgery \u2014 procedures on the vitreous and retina such as pars plana vitrectomy, retinal detachment repair, and related posterior segment surgery. It is maintained by the AMA and is distinct from CPT 00140, which is the not-otherwise-specified (NOS) catch-all code for eye procedures that do not have a dedicated code.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568812\"><h3 class=\"schema-faq-question\">How many base units does CPT 00145 have?<\/h3> <p class=\"schema-faq-answer\">CPT 00145 carries 6 anesthesia base units per the ASA Relative Value Guide. Base units reflect the inherent complexity of the procedure type and are combined with time units, and any modifying units recognized by the payer, to calculate the total billable units before applying the payer&rsquo;s conversion factor.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568813\"><h3 class=\"schema-faq-question\">What modifiers apply to CPT Code 00145?<\/h3> <p class=\"schema-faq-answer\">Three modifier categories apply: practitioner-type modifiers (AA for personally performed, QX\/QK for medically directed, QZ for independent CRNA), physical status modifiers (P1-P6), and qualifying circumstance add-on codes (99100, 99116, 99135, 99140). At least one practitioner-type modifier is required on every 00145 claim. Physical status and qualifying circumstance modifiers may add units for commercial payers that follow the ASA RVG, but Medicare does not pay separately for either category.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568814\"><h3 class=\"schema-faq-question\">How is anesthesia reimbursement calculated for CPT 00145?<\/h3> <p class=\"schema-faq-answer\">Reimbursement is calculated as: (Base Units + Time Units + Modifying Units) multiplied by the conversion factor. Time units are typically 1 per 15 minutes of documented anesthesia time. For Medicare, the calculation also applies a Geographic Practice Cost Index (GPCI) adjustment by MAC locality, and Medicare&rsquo;s formula excludes physical status and qualifying circumstance units entirely, so national averages do not reflect local Medicare allowables.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568815\"><h3 class=\"schema-faq-question\">Does Medicare cover CPT Code 00145?<\/h3> <p class=\"schema-faq-answer\">Yes, Medicare covers CPT Code 00145 when medically necessary and properly documented. Payment varies based on the modifier used: AA and QZ claims are paid at 100% of the calculated allowable, while QK\/QX medically directed cases split payment at 50% between the anesthesiologist and the CRNA, and AD (supervision of 5+ concurrent cases) is paid at 3 base units only. Physical status modifiers (P1-P6) add zero payable units under Medicare, and qualifying circumstance codes (99100, 99116, 99135, 99140) are bundled (status B) and not paid separately.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568816\"><h3 class=\"schema-faq-question\">What ICD-10-CM codes are commonly billed with CPT 00145?<\/h3> <p class=\"schema-faq-answer\">The most common diagnosis codes paired with CPT 00145 include H33.011 (retinal detachment with single break), E11.3511 (proliferative diabetic retinopathy with macular edema), H43.11 (vitreous hemorrhage), H44.011 (panophthalmitis\/endophthalmitis), and H35.371 (macular pucker). Strabismus diagnosis codes such as H50.9 or H50.411 do not pair with 00145; strabismus repair is billed under CPT 00140, not 00145.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568817\"><h3 class=\"schema-faq-question\">What documentation is required for billing CPT 00145?<\/h3> <p class=\"schema-faq-answer\">Required documentation includes: a pre-anesthesia evaluation with physical status classification (P1-P6) and clinical justification, the intraoperative anesthesia record with exact start and stop times, vital signs, and agents used, documentation establishing the practitioner-type modifier applied, any qualifying circumstance justification for payers that recognize it, and a post-anesthesia recovery note. Every element must be present to withstand payer audit review.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784874568818\"><h3 class=\"schema-faq-question\">What is the difference between CPT 00140 and CPT 00145?<\/h3> <p class=\"schema-faq-answer\">CPT 00140 is the not-otherwise-specified (NOS) catch-all code for eye procedures that do not have a dedicated anesthesia code \u2014 it carries 5 base units and is the code used for procedures such as strabismus repair. CPT 00145 is specifically for vitreoretinal surgery (vitrectomy, retinal detachment repair, and related posterior segment procedures) and carries 6 base units. Use 00145 only when the procedure is genuinely vitreoretinal; default to 00140 when no other code in the 00140-00148 family fits.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>CPT Code 00145 is the anesthesia procedure code for vitreoretinal surgery \u2014 procedures such as pars plana vitrectomy, retinal detachment repair, and related posterior segment surgery.
