CPT code 23929 is subject to reimbursement by Medicare, but it is essential to verify its status through the Medicare Physician Fee Schedule (MPFS) and consult with your regional Medicare Administrative Contractor (MAC). The MPFS provides a comprehensive list of services covered by Medicare, including their respective reimbursement rates. However, since CPT code 23929 is an unlisted procedure code, its reimbursement is not straightforward and typically requires additional documentation to justify the medical necessity and appropriateness of the service provided. Therefore, it is crucial to work closely with your MAC to ensure all necessary information is submitted to facilitate proper reimbursement.
