Billing tips

Document muscle layer involvement explicitly in operative report with specific muscle names (e.g., zygomaticus, orbicularis oris, platysma) and describe repair technique
Impact: Critical for medical necessity justification; prevents downcoding to simple repair codes (12000-13000 series) which reimburse $100-400 less
Measure and document defect size in centimeters and specify anatomical location using precise facial landmarks before and after debridement
Impact: Supports complexity level and prevents denial; dimension documentation prevents challenges to code selection
When performed after Mohs surgery or tumor excision, ensure separate documentation of the reconstruction as distinct from the excision procedure
Impact: Enables billing both excision code and 15845; can add $300-800 to total reimbursement when properly separated
For staged procedures, document in initial operative note that secondary procedures are planned, and reference prior surgery in subsequent operative reports
Impact: Justifies modifier 58 use and ensures full $1043.17 payment for each stage rather than bundled denial
Photograph defect before repair and after closure; include in medical record with measurements and anatomical landmarks labeled
Impact: Reduces audit risk and strengthens appeals; visual documentation can prevent denials worth full procedure value
Avoid billing same-day E/M unless significant separately identifiable service with modifier 25 and distinct documentation
Impact: Prevents automatic denial of E/M; when appropriate, can add $100-200 for medically necessary evaluation

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 15845 in 2025?

The 2025 Medicare national average reimbursement for CPT 15845 is $1043.17 for both facility and non-facility settings, based on a total RVU of 32.25 and conversion factor of 32.3465.

Can CPT 15845 be billed with Mohs surgery on the same day?

Yes, CPT 15845 can be billed separately from Mohs surgery (17311-17315) when the reconstruction involves skin and muscle repair and is documented as a distinct procedure. Ensure the operative report clearly separates the Mohs excision from the subsequent reconstruction and documents muscle layer involvement.

What documentation is required to bill CPT 15845 instead of simple facial repair codes?

Documentation must explicitly identify the specific facial muscle(s) involved in the defect, describe layer-by-layer repair of both muscle and skin, include defect measurements, and explain why muscle repair was medically necessary. Photographs showing muscle exposure strengthen the documentation.

What is the difference between CPT 15845 and intermediate facial repair codes?

CPT 15845 requires repair of both skin and underlying muscle layers, while intermediate repairs (12051-12057) involve layered closure of skin and subcutaneous tissue only without muscle involvement. The work RVU difference is substantial: 15845 has 14.32 work RVUs versus 2.5-5.0 for intermediate repairs.

How many RVUs is CPT code 15845 worth?

CPT 15845 has a total RVU value of 32.25, consisting of 14.32 work RVUs, 15.3 practice expense RVUs, and 2.63 malpractice RVUs for 2025.

Is CPT 15845 considered cosmetic or reconstructive surgery?

CPT 15845 is typically reconstructive when performed to repair defects from trauma, tumor removal, infection, or congenital deformities. It is considered cosmetic if performed solely for aesthetic enhancement without functional impairment. Medical necessity documentation with appropriate diagnosis codes (trauma, neoplasm removal, etc.) is essential for coverage.

What modifiers are commonly used with CPT 15845?

Common modifiers include 50 (bilateral procedure), 51 (multiple procedures), 58 (staged procedure during global period), 78 (return to OR for complication), 79 (unrelated procedure during global period), and 22 (increased procedural services for unusual complexity). Each modifier has specific documentation requirements and reimbursement impacts.
