Its official descriptor for CPT code 01270 reads: <strong>Anesthesia for procedures on arteries of upper leg, including bypass graft; not otherwise specified.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clinically, this code applies when an anesthesiologist or Certified Registered Nurse Anesthetist (CRNA) provides anesthesia for open vascular procedures on the femoral or iliac arteries. The most common surgical trigger is a femoral-popliteal (fem-pop) bypass graft performed to treat peripheral arterial occlusive disease.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The &#8222;not otherwise specified&#8220; qualifier makes 01270 the catch-all code for upper-leg artery procedures. It applies whenever no more specific code in the 01270 series describes what the surgeon did.<\/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\">Detail<\/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\">01270<\/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\">Anesthesia for procedures on arteries of upper leg, including bypass graft; not otherwise specified<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Code section<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia for procedures on the lower extremities (00300-01999)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Base units (ASA RVG)<\/td>\n<td style=\"padding:12px 16px;color:#374151\">8<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Clinical provider<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesiologist or CRNA (independently or under medical direction)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Primary surgical context<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Femoral-popliteal bypass graft, femoral artery endarterectomy, iliac artery procedures<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<h2 class=\"wp-block-heading\">Anesthesia base units and what they measure<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT code 01270 carries <strong>8 base units<\/strong> as assigned by the American Society of Anesthesiologists (ASA) Relative Value Guide (RVG). Base units reflect the complexity of the anesthesia service, independent of how long the case runs. A fem-pop bypass under general anesthesia is more demanding than a peripheral nerve block for an outpatient procedure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adjacent codes in the lower-extremity family carry their own values. Obstetric anesthesia codes such as 01969 carry values of their own. Never carry a base unit figure from one code across to another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ASA RVG base unit assignment and the CMS-assigned base unit value can differ, which trips billing teams up regularly. For most payers, the ASA value of 8 units is the operative figure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare billers should still check the current CMS anesthesia base unit file before submitting. You can look up current values with the <a href=\"https:\/\/www.cms.gov\/medicare\/physician-fee-schedule\/search\/overview\" target=\"_blank\" rel=\"nofollow noopener\">CMS Physician Fee Schedule tool<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How anesthesia billing works: the B+T+M formula<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Anesthesia billing follows a different formula from standard surgical CPT codes. Where a surgeon bills a flat fee per procedure, anesthesia reimbursement moves with time. The formula, set out in the CMS Medicare Claims Processing Manual, is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Payment = (B + T + M) x Conversion Factor<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>B (Base Units):<\/strong> The ASA-assigned value for the specific anesthesia code. For CPT code 01270, B = 8.<\/li><li><strong>T (Time Units):<\/strong> One time unit per 15 minutes of anesthesia service. A 90-minute fem-pop bypass = 6 time units.<\/li><li><strong>M (Modifying Units):<\/strong> Units added by qualifying circumstance codes (99100-99140) that reflect additional clinical complexity. Physical status modifiers are noted on the claim but do not always add units directly under Medicare rules.<\/li><li><strong>Conversion Factor:<\/strong> The dollar value CMS assigns per anesthesia unit, updated annually. Verify the current figure at cms.gov before billing.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Worked example:<\/strong> A patient with mild systemic disease (P2) undergoes a 2-hour femoral artery bypass graft.

Medicare auditors routinely flag claims where documented time does not align with the OR schedule. A 15-minute discrepancy can shift the total units by one, triggering a recoupment demand. Build a timestamped intraoperative record into your standard workflow before each case closes.<\/p>\n            <\/div>\n        <\/div>\n    \n\n\n<h2 class=\"wp-block-heading\">Medicare fee schedule and reimbursement<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare reimbursement for anesthesia services uses the B+T+M formula above, adjusted by geographic payment locality. CMS publishes updated anesthesia base unit files and conversion factors each year in the Physician Fee Schedule Final Rule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For CY2026, the CMS anesthesia conversion factor is $20.4976. It rises to $20.5998 for clinicians who qualify as Advanced Alternative Payment Model (APM) participants. The factor that applies is the one in force on the date of service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Geographic Practice Cost Indices (GPCI) adjust the final payment for regional differences in the cost of providing care. A 90-minute femoral bypass in Manhattan pays more than the same case and time in rural Mississippi. The unit count is identical either way. Use the <a href=\"https:\/\/fastrvu.com\/tools\/rvu-lookup\" target=\"_blank\" rel=\"nofollow noopener\">FastRVU lookup tool<\/a> to cross-check locality-adjusted values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Commercial payer rates sit well above Medicare, often by a wide margin. Published work from the GAO, the Urban Institute, and anesthesia member surveys puts average commercial anesthesia rates at roughly 300-400% of Medicare.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So Medicare figures work as a floor for negotiation rather than a forecast of commercial payment. Always check the contracted rate in your own payer agreement before quoting a number. Practice management software like Pabau handles <a href=\"https:\/\/pabau.com\/features\/claims-management-software\/\">anesthesia claims management<\/a> across payers, so nobody reconciles contracted rates by hand.<\/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-01270\/track-claims-from-start-to-finish.webp\" alt=\"Pabau claims management dashboard tracking a claim from submission to payment\"\/><figcaption class=\"wp-element-caption\"><em>Pabau&#8217;s claims management dashboard follows each 01270 claim from submission to payment, so a denial surfaces the week it lands.<\/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\">Modifiers you need on an 01270 claim<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Anesthesia billing asks for more modifier precision than most CPT categories.

Missing any of these is a common audit finding, and a preventable reason for a denial.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Pre-anesthesia evaluation:<\/strong> Completed before induction. It documents ASA physical status classification, relevant medical history, airway assessment, and the planned anesthetic technique. A signed medical consent form belongs in the same chart.<\/li><li><strong>Intraoperative anesthesia record:<\/strong> Continuous monitoring data, plus a drug administration log with times and doses. Most critically, it carries the anesthesia start and stop times that drive the time unit count.<\/li><li><strong>Post-anesthesia note:<\/strong> Brief note confirming patient condition, recovery, and anesthesia provider attestation. Must be completed before discharge from PACU.<\/li><li><strong>Medical necessity documentation:<\/strong> The surgeon&#8217;s procedure note links the surgical diagnosis to the procedure performed. That link is what confirms the clinical basis for the bypass graft.<\/li><li><strong>Modifier support documentation:<\/strong> If a qualifying circumstance code is billed (99100, 99140, etc.), the anesthesia record must contain the clinical evidence supporting that add-on code.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Inadequate time documentation is the deficiency anesthesia audits cite most often. Practices working from secure patient data tools have a stronger audit trail when a payer asks for records. When a third party wants those records outside treatment or payment, a HIPAA waiver form documents the patient&#8217;s authorization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">CRNA vs anesthesiologist billing under CPT code 01270<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Modifier selection between CRNAs and physician anesthesiologists is legally significant under CMS rules, per Chapter 12 of the Medicare Claims Processing Manual. Choose wrong and the practice either underbills the case or takes on compliance risk it did not intend.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Personally performed (AA):<\/strong> When the anesthesiologist is the sole provider and personally performs the anesthesia without concurrent direction of other cases, modifier AA applies. Medicare pays 100% of the allowed amount to the billing anesthesiologist. This is the highest reimbursement scenario for a single provider.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Medically directed CRNA (QK + QX):<\/strong> When an anesthesiologist medically directs 2-4 concurrent CRNA cases, each claim splits 50\/50. The anesthesiologist bills 01270-QK for roughly half the allowed amount, and the CRNA bills 01270-QX for the other half. Check the current CMS percentages before billing, because the guidance can change each year.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Independent CRNA (QZ):<\/strong> A CRNA practicing with no physician involvement, in a state that allows independent practice, bills 01270-QZ. That claim pays 100% of the Medicare allowed amount. QZ is distinct from QX, which requires a directing physician.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conflating QZ and QX is a documented fraud and abuse pattern flagged by the OIG, so check your state&#8217;s opt-out status before billing under QZ. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related anesthesia CPT codes in the 01270 series<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CPT code 01270 sits in a family of anesthesia codes for lower-extremity vascular and joint procedures. Picking the correct adjacent code matters, because each one carries a different base unit value and a different surgical trigger.<\/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\">Descriptor<\/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\">Base Units<\/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 Instead of 01270<\/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\">01260<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia for procedures involving veins of upper leg, including exploration<\/td>\n<td style=\"padding:12px 16px;color:#374151\">3<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Venous procedure, not arterial<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">01270<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Arteries of upper leg, including bypass graft; NOS<\/td>\n<td style=\"padding:12px 16px;color:#374151\">8<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Primary code for fem-pop bypass and femoral artery NOS procedures<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\"><a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-01272\/\">01272<\/a><\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia for procedures on arteries of upper leg; femoral artery ligation<\/td>\n<td style=\"padding:12px 16px;color:#374151\">4<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Ligation of a femoral artery<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">01274<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia for procedures on arteries of upper leg; femoral artery embolectomy<\/td>\n<td style=\"padding:12px 16px;color:#374151\">6<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Embolectomy of a femoral artery<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">01480<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Anesthesia for open procedures on bones of lower leg, ankle, and foot<\/td>\n<td style=\"padding:12px 16px;color:#374151\">3<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Orthopedic procedure, not vascular<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">What separates 01270 from 01272 and 01274 is the surgical procedure itself.

When it documents an embolectomy, 01274 applies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CPT code 01270 stays correct for a bypass graft, or any femoral or iliac artery procedure with no more specific descriptor. Anesthesia for a hip joint procedure falls outside this family and codes to 01212. The facility side of the same case can also generate device and supply codes such as C1714.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related CPT codes<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-00940\/\">CPT code 00940 \u2014 Anesthesia for vaginal procedures<\/a><\/li>\n\n\n<li><a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-01320\/\">CPT code 01320 \u2014 Anesthesia for knee and popliteal area procedures<\/a><\/li>\n\n\n<li><a href=\"https:\/\/pabau.com\/procedure-codes\/cpt-code-01340\/\">CPT Code 01340 \u2014 Anesthesia for closed distal femur procedures<\/a><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Pabau keeps anesthesia claims off the rework queue<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Anesthesia billing teams often reconcile three sources by hand. The anesthesia record holds the start and stop times, the schedule holds the case, and the claim file holds the modifier. When one disagrees with another, the mismatch usually surfaces after the denial arrives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pabau keeps the case, the record, and the claim in one system. Time stamps come from the same record an auditor would read. Modifier rules sit with the claim, so a QZ submission cannot leave on a medically directed case.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That structure holds for any practice billing procedure codes across several payers. Fewer claims come back for rework, and payment lands sooner.<\/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                    Reduce anesthesia claim denials with Pabau                <\/h3>\n\n                <p class=\"description\">\n                    Pabau&#8217;s claims management software helps anesthesia billing teams track modifier assignments, time documentation, and payer-specific reimbursement rules, so fewer claims come back as errors.                <\/p>\n\n                <div class=\"button-group\">\n                    <a href=\"\/book-demo\/\" class=\"btn btn-scale-effect btn-cta-color btn-md\">\n                        <span class=\"btn-text\">Book a demo<\/span>\n                        <div class=\"btn-icon btn-icon-right\" aria-hidden=\"true\">\n                            <svg\n                                width=\"14\"\n                                height=\"12\"\n                                viewBox=\"0 0 14 12\"\n                                fill=\"none\"\n                                xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\n                            >\n                                <path\n                                    d=\"M0.75 4.77295C0.335786 4.77295 0 5.10874 0 5.52295C0 5.93716 0.335786 6.27295 0.75 6.27295V5.52295V4.77295ZM13.2803 6.05328C13.5732 5.76039 13.5732 5.28551 13.2803 4.99262L8.50736 0.219648C8.21447 -0.073245 7.73959 -0.073245 7.4467 0.219648C7.15381 0.512542 7.15381 0.987415 7.4467 1.28031L11.6893 5.52295L7.4467 9.76559C7.15381 10.0585 7.15381 10.5334 7.4467 10.8263C7.73959 11.1191 8.21447 11.1191 8.50736 10.8263L13.2803 6.05328ZM0.75 5.52295V6.27295L12.75 6.27295V5.52295V4.77295L0.75 4.77295V5.52295Z\"\n                                    fill=\"currentColor\"\n                                ><\/path>\n                            <\/svg>\n                        <\/div>\n                    <\/a>\n                <\/div>\n            <\/div>\n\n            <div class=\"right-side\">\n                <img decoding=\"async\"\n                    src=\"https:\/\/pabau.com\/wp-content\/uploads\/2026\/01\/Home-Page-Concept-4.webp\"\n                    alt=\"Pabau claims management dashboard\"\n                    loading=\"lazy\"\n                \/>\n            <\/div>\n        <\/div>\n        \n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Anesthesia claims on this code usually fail on small things. A base unit figure taken from the wrong source costs the practice money. So does a QK where a QZ belonged, or a start time that misses the OR log by a quarter of an hour.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The work worth doing sits upstream of the claim. Pin the base unit figure to the current ASA and CMS files. Capture times in the record as the case happens, not from memory afterward. Let the modifier follow the staffing arrangement rather than habit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off is that none of this stays fixed. Conversion factors change every January, and state CRNA rules move on their own schedule. So the check belongs in a routine, not a project. <a href=\"https:\/\/pabau.com\/book-demo\/\">Book a demo<\/a> to see how Pabau tracks modifiers, time units, and payer rules on anesthesia

asked questions<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1785753202220\"><h3 class=\"schema-faq-question\">What is CPT code 01270 used for?<\/h3> <p class=\"schema-faq-answer\">CPT code 01270 is used to bill anesthesia services for procedures on the arteries of the upper leg, including bypass grafts, not otherwise specified. The most common clinical application is anesthesia for a femoral-popliteal bypass graft performed to treat peripheral arterial occlusive disease. It covers cases where a more specific anesthesia code in the 01270 series does not apply.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785753202221\"><h3 class=\"schema-faq-question\">How many base units does CPT 01270 have?<\/h3> <p class=\"schema-faq-answer\">CPT code 01270 carries 8 base units as assigned by the ASA Relative Value Guide. Base units represent the complexity of the anesthesia service. They form the &#8222;B&#8220; component of the B+T+M formula, before time units and modifying units are added.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785753202222\"><h3 class=\"schema-faq-question\">What modifiers apply to CPT code 01270?<\/h3> <p class=\"schema-faq-answer\">Three modifier families apply. Physical status modifiers (P1-P6) are required on every anesthesia claim. Qualifying circumstance add-on codes (99100, 99116, 99135, 99140) go on when clinically triggered. Medical direction modifiers cover AA for personally performed cases and QK plus QX for medically directed ones. QY covers direction of one CRNA, and QZ covers independent CRNA billing.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785753202223\"><h3 class=\"schema-faq-question\">Can a CRNA bill under CPT code 01270?<\/h3> <p class=\"schema-faq-answer\">Yes, a CRNA can bill CPT code 01270 using modifier QZ when practicing independently without physician direction, receiving 100% of the Medicare allowed amount. When under physician medical direction, the CRNA bills modifier QX and receives roughly 50% of the allowed amount. The directing anesthesiologist bills QK for the remaining 50%.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785753202224\"><h3 class=\"schema-faq-question\">How is anesthesia billing calculated using the B+T+M formula?<\/h3> <p class=\"schema-faq-answer\">Anesthesia payment equals (Base Units + Time Units + Modifying Units) multiplied by the CMS conversion factor. For CPT code 01270, base units = 8. Time units are calculated as one unit per 15 minutes of anesthesia service. Modifying units come from qualifying circumstance add-on codes. The result is multiplied by the current year&#8217;s CMS anesthesia conversion factor and adjusted by geographic GPCI values.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785753202225\"><h3 class=\"schema-faq-question\">What is the difference between CPT 01270 and CPT 01272?<\/h3> <p class=\"schema-faq-answer\">Both codes cover anesthesia for procedures on the arteries of the upper leg, but they differ in specificity and in base units. CPT code 01270 is the &#8222;not otherwise specified&#8220; code and carries 8 base units. CPT 01272 covers femoral artery ligation and carries 4 base units. When the operative report documents a ligation, 01272 is the correct code. For bypass grafts and unspecified procedures, 01270 applies.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>CPT code 01270 covers anesthesia for procedures on arteries of the upper leg, including femoral-popliteal bypass grafts.
