CPT code 24400 is a medical billing code used to describe the surgical procedure for the revision of the humerus. This involves the correction or modification of a previous surgery on the upper arm bone, known as the humerus. This procedure may be necessary due to complications, improper healing, or other issues that require surgical intervention to ensure proper function and alignment of the arm.

The CPT code 24400 is reimbursed by Medicare, but it is essential to verify its specific reimbursement status through the Medicare Physician Fee Schedule (MPFS). The MPFS provides detailed information on the payment rates for services covered under Medicare Part B. Additionally, Medicare Administrative Contractors (MACs) play a crucial role in determining the local coverage and reimbursement policies for CPT codes. Therefore, while CPT code 24400 is generally reimbursed by Medicare, healthcare providers should consult the MPFS and their respective MAC for precise details on coverage and payment rates.
