About CPT 36475
CPT 36475 is a Current Procedural Terminology code in the Surgery (Respiratory/Cardiovascular) category maintained by the American Medical Association. The CMS short descriptor reads "Endovenous rf 1st vein". For the full AMA long descriptor and clinical guidance, refer to the current CPT code manual.
Documentation specificity, correct ICD-10 linkage, and modifier accuracy determine whether 36475 pays cleanly or triggers a denial. Verify CMS National Physician Fee Schedule status, applicable Medicare LCDs, and any payer-specific medical policies before submission.
36475 has 10 NCCI bundling edit pairs documented. Run your scrubber against the NCCI quarterly update before submission. When clinically warranted, use modifier 59 or the X-modifiers (XE, XS, XP, XU) to bypass an indicator-1 edit, with chart documentation supporting the distinct service.
Code Properties
RVU Breakdown
Every CPT code’s Medicare payment is calculated from three Relative Value Unit components: physician work, practice expense, and malpractice. Together they multiply by the conversion factor to produce the payment amount.
Payment = Total RVU × Conversion Factor ($33.4009) × Geographic Adjustment (GPCI). National averages shown. Actual payment varies by locality.
Medicare Payment by State
Medicare adjusts payment by locality based on GPCI (Geographic Practice Cost Index). Higher cost-of-living areas like California and New York pay more. Rural states pay less. Top 12 states shown.
Showing top 12 of 53 states. Full locality data available in CMS PFS Locality file.
NCCI Bundling Edits
10 pairsThese codes trigger National Correct Coding Initiative edits when billed with 36475. An indicator of 0 means the pair cannot be unbundled. Indicator 1 means modifier 59 or X-modifiers may allow separate billing with supporting documentation.
36475 + 0213T: hard bundle (indicator 0)
The most-asked bundling question on this code. Verdict pulled from the current NCCI quarterly file.
Modifier indicator 0 means this edit cannot be bypassed. Do not append modifier 59 or X-modifiers. The bundled code must be written off, or, if clinically inappropriate, the entire claim reconsidered.
Misuse of Column Two code with Column One code
Billing 36475 alongside a bundled code without the correct modifier generates CARC 97 denials. Payers often flag these as audit risks. Document medical necessity for the separate service and apply modifier 59 or the appropriate X-modifier (XE, XS, XP, XU) only when clinically justified.

Multi-procedure NCCI edits hit surgical specialties harder than any other category. CO-97 denials on 36475 are frequently recoverable when the operative note documents distinct anatomic sites or staged steps. Our coders read the op note against the edit pair and pick the right modifier (XS preferred over modifier 59 for distinct structures).

Indicator 0 means no modifier bypasses the edit. A real coder should confirm before the charge is written off. Some look-alike edits get appealed successfully on documentation grounds.

Supporting ICD-10 Diagnoses
These diagnosis codes commonly support medical necessity for CPT 36475. Using the correct ICD-10 prevents CARC 50 denials. Payer rejects when the diagnosis doesn’t support the procedure.
Surgical CO-50 denials usually trace to ICD-10 specificity gaps (E11.9 instead of E11.65, M17.11 instead of M17.0, etc.). Our coders map every diagnosis to the highest-specificity code the chart supports, eliminating the common medical-necessity denial pattern.
