About CPT 11771
CPT 11771 is a Current Procedural Terminology code in the Anesthesia category maintained by the American Medical Association. The CMS short descriptor reads "Exc pilonidal cyst xtnsv". For the full AMA long descriptor and clinical guidance, refer to the current CPT code manual.
Major surgical codes carry a 90-day global period that bundles all related post-operative care. Improper billing of post-op E/M (without modifier 24 for unrelated care) is a common audit finding. Documentation of medical necessity for the procedure itself remains the foundation of any successful claim.
CPT 11771 has a 90-day global period. Any E/M visit within that window for the same condition is bundled into the procedure payment. Use modifier 24 for unrelated E/M, modifier 79 for unrelated procedures, and modifier 78 for related returns to the OR.
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.

NCCI Bundling Edits
10 pairsThese codes trigger National Correct Coding Initiative edits when billed with 11771. 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.
11771 + 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 11771 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.

More extensive procedure
Bundling denials on 11771 are recoverable when the edit indicator is 1 and the chart documents a distinct, separately identifiable service. Our coders verify the indicator and pick the precise X-modifier (XE, XS, XP, XU) instead of defaulting to modifier 59.

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.
