CPT Code 21120 Medicare Reimbursement

Medicare reimbursement for CPT code 21120, which pertains to the reconstruction of the chin, depends on several factors including medical necessity, the setting in which the procedure is performed, and the specific Medicare Administrative Contractor (MAC) policies in your region.

Generally, Medicare does cover reconstructive surgeries if they are deemed medically necessary. For CPT code 21120, this would typically mean that the procedure is required to correct a functional impairment or to address a significant deformity resulting from trauma, disease, or congenital anomalies.

However, if the procedure is considered cosmetic, Medicare will not provide reimbursement. It is crucial to provide comprehensive documentation that supports the medical necessity of the procedure to ensure coverage.

The reimbursement amount can vary based on the geographic location and the specific Medicare fee schedule applicable to your practice. As of the latest available data, the national average reimbursement for CPT code 21120 under Medicare Part B is approximately $1,200. However, this amount can fluctuate, so it is advisable to consult the current Medicare Physician Fee Schedule or your local MAC for the most accurate and up-to-date reimbursement rates.

For precise information, healthcare providers should verify the coverage and reimbursement details with their local MAC and ensure that all necessary documentation is in place to support the claim.
