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 exact tumor measurements in three dimensions with specific notation that maximum dimension is ≥5cm; measurements should be from pathology report or intraoperative findings
Impact: Prevents downcoding to smaller tumor codes (22902, 22903) which carry significantly lower RVUs and reimbursement
Clearly differentiate 'deep' location in operative note by documenting tumor depth below fascial planes, relationship to muscle layers, and retroperitoneal or intraabdominal location
Impact: Justifies use of 22901 versus superficial excision codes; lack of depth documentation can result in denial or $400+ reimbursement reduction
Submit detailed operative report with modifier 22 claims showing increased complexity factors: vascular involvement, nerve preservation, organ mobilization, or reconstruction requirements
Impact: Can increase reimbursement by $131-$328 (20-50% above base rate) when properly documented and appealed
Verify tumor size threshold before surgery; if borderline 4.5-5.5cm range, document multiple measurement methods and use largest dimension from any imaging or pathology
Impact: Ensures appropriate code selection; size discrepancies are common audit triggers that can delay or deny payment
Bill facility versus non-facility setting correctly; confirm place of service code matches actual location (hospital=21-23, ASC=24)
Impact: Both settings reimburse identically at $656.96 for 22901, but incorrect POS codes trigger automatic denials requiring resubmission
When billing with reconstruction codes, sequence 22901 as primary procedure and use modifier 51 on secondary codes; document medical necessity for reconstruction separate from tumor removal
