Financial Disparities in Microsurgical Reconstruction: Reimbursement Analysis of Head & Neck versus Breast Microsurgery

BACKGROUND: Microsurgical reconstruction is a resource-intensive and technically demanding subspecialty with differing clinical indications. Head and neck (H&N) cancer patients are medically complex, require large, immediate reconstructions with variable tissue needs, and experience prolonged postoperative courses. In contrast, free-flap breast reconstruction is typically elective, performed in healthier patients, and associated with shorter recoveries. This study compares provider and institutional reimbursement patterns between microsurgical domains to evaluate differences reflected in compensation. METHODS: A retrospective review identified patients undergoing H&N or breast free-flap reconstruction from 2016–2023 at a single academic institution in Mississippi providing microsurgical care. Demographics, perioperative data, provider and hospital charges/reimbursement, and efficiency metrics were analyzed. RESULTS: There were 136 H&N and 140 breast flap patients. Operative times were similar (H&N: 546.7 vs. breast: 569.8 minutes; p=0.133). H&N patients had longer hospital stays (7.7 days longer; p<0.001). Provider reimbursement was higher for breast in total ($7,272 vs. $2,950; p<0.001) and per operative minute ($13.00 vs. $5.81; p<0.001). Hospitals received greater payments for H&N flaps ($49,930 vs. $17,593; p<0.001), driven by prolonged hospitalizations, while breast flaps yielded higher payment per admission day. Medicaid percentage of charges reimbursed strongly favored breast reconstruction (53.4% vs. 29.9%; p=0.003). CONCLUSIONS: Breast flaps provide higher provider reimbursement and value per operative minute, whereas H&N flaps generate higher institutional payments due to longer hospitalizations. These findings highlight shortcomings in reimbursement structures to reflect procedure complexity and patient burden within microsurgery. Financial disincentives of specialized care may threaten access to complex reconstructive services.
