Code 23485 covers revision surgery to correct or repair a previous collarbone operation that didn't heal properly or developed complications. Patients typically need this after failed fracture repairs, hardware problems, or infections from initial clavicle surgery. This revision procedure charges approximately 12.5x the Medicare reimbursement rate, with potential billing differences of $2,800 between outpatient and inpatient settings.

Common billing errors
Common billing errors in musculoskeletal procedures often involve confusion between arthroscopy codes (29800-29999 series) and open joint procedures (27000-28000 series), where providers may bill the higher-reimbursed open procedure when arthroscopic methods were used. Unbundling frequently occurs with injection procedures, where separate billing for imaging guidance (such as fluoroscopy code 77002) appears alongside joint injection codes that already include guidance in their description. Duplicate charges emerge when both diagnostic and therapeutic arthroscopy codes are billed for the same joint during a single session, despite Medicare's bundling rules. Physical therapy evaluation codes (97161-97163) are commonly duplicated across multiple sessions when only initial evaluations warrant these specific codes. Patients should verify that hardware removal procedures aren't billed separately when performed during the same operative session as implant placement, as these combinations often represent charges above the benchmark for standard bundled procedures. Documentation should clearly support any bilateral procedure modifiers that significantly increase reimbursement rates.
