Exc skn h/p/p/u complex
CPT 11471 covers the surgical removal of complex skin lesions on the hands, feet, neck, or genitals. These excisions require more extensive work due to location complexity, lesion characteristics, or closure difficulty.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Document specific complexity factors justifying 11471 vs simple excision codes (11420-11426). Include anatomic challenges, closure technique (layered, undermining extent), or patient factors.
Impact: Difference between 11471 ($526.60) and simple excision codes ($150-$300) represents $200-$370 per procedure in proper reimbursement
Bill non-facility rate ($526.60) when performed in office-based setting; facility rate ($345.78) applies only in hospital/ASC where facility bills separately for overhead
Impact: Ensures proper reimbursement differential of $180.82 per procedure based on practice setting
When multiple lesions excised, sequence codes by RVU value (bill highest RVU first without modifier 51, then append 51 to subsequent codes) to maximize reimbursement
Impact: Proper sequencing prevents losing 50% reduction on highest-paying procedure; can save $150-$250 per session
Submit pathology report with claim or have available for audit; many payers require histopathologic confirmation to support medical necessity of excision
Impact: Reduces denial rate by 30-40% and accelerates clean claim payment; prevents medical necessity denials
For lesions near size threshold between 11471 and other excision codes in same family, document excised diameter plus margins in operative note, not just pathology specimen size
Impact: Pathology specimens shrink 10-30% in formalin; operative measurement supports code selection and prevents downcoding
Use specific anatomic documentation (e.g., 'dorsal hand overlying third metacarpal' rather than just 'hand') to support complexity designation and prevent payer downcoding
