CPT code 21299 is used for procedures on the craniofacial and maxillofacial areas that don't have a specific code.
CPT code 21299 is used for procedures involving the craniofacial and maxillofacial areas that do not have a specific code assigned to them. This is an "unlisted" code, meaning it covers surgeries or treatments in these regions that are not otherwise categorized.
When dealing with CPT code 21299, which is an unlisted craniofacial and maxillofacial procedure, it is essential to understand that this code may require specific modifiers to provide additional information about the service rendered. Below is a list of potential modifiers that could be used with CPT code 21299 and the reasons for their use:
1. Modifier 22 - Increased Procedural Services
- Used when the work required to provide a service is substantially greater than typically required. Documentation must support the substantial additional work and the reason for the additional work.
2. Modifier 52 - Reduced Services
- Indicates that a service or procedure is partially reduced or eliminated at the physician's discretion. This modifier is used when the procedure is not completed in its entirety.
3. Modifier 53 - Discontinued Procedure
- Used when a procedure is started but discontinued due to extenuating circumstances or those that threaten the well-being of the patient.
4. Modifier 59 - Distinct Procedural Service

- Used when a patient requires a return to the operating room for a related procedure during the postoperative period of the initial procedure.

- Indicates that the performance of a procedure or service during the postoperative period was unrelated to the original procedure.
9. Modifier 80 - Assistant Surgeon

10. Modifier 81 - Minimum Assistant Surgeon
- Indicates that a minimum assistant surgeon was required during the procedure.
11. Modifier 82 - Assistant Surgeon (when qualified resident surgeon not available)

Determining whether Medicare reimburses for CPT code 21299, which is an unlisted craniofacial and maxillofacial procedure, requires a nuanced approach. Medicare does not have a predetermined fee schedule for unlisted codes like 21299. Instead, reimbursement is contingent upon the submission of detailed documentation that justifies the medical necessity and complexity of the procedure.
To facilitate reimbursement, healthcare providers must submit a comprehensive report that includes:
1. A detailed description of the procedure performed.
2. The reason why a specific CPT code does not exist for the procedure.
3. Comparable procedures and their respective CPT codes for reference.
4. Supporting clinical documentation, such as operative reports and patient history.
The reimbursement amount for CPT code 21299 is not standardized and will be determined on a case-by-case basis by the Medicare Administrative Contractor (MAC). Providers should consult their local MAC for guidance on the documentation required and the potential reimbursement amount.
In summary, while Medicare does reimburse for CPT code 21299, the amount is variable and dependent on the thoroughness of the submitted documentation. Providers should ensure they provide all necessary details to facilitate the review and reimbursement process.
