About 21242: Mandibular condyle reconstruction with autogenous graft
Rebuilds a damaged or absent mandibular condyle using the patient’s bone and cartilage, commonly for major temporomandibular joint defects.
This operation rebuilds the mandibular condyle, the jaw’s joint-forming portion, with the patient’s bone and cartilage. A costochondral graft is a familiar approach. Oral and maxillofacial or other qualified surgeons may perform it for major condylar loss associated with trauma, ankylosis, congenital deformity, or destructive disease, usually in a hospital operating room.
Report the code when the reconstruction uses autogenous bone and cartilage; an alloplastic condylar reconstruction is distinguished by 21243. The operative report should identify the defect, side, reconstructive method, and graft material and source. The 90-day global period includes the day-before preoperative visit and related postoperative care. With another procedure in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

21242 billing questions
How does 21242 differ from 21243?

When would 21240 be considered instead?
21240 describes temporomandibular joint arthroplasty. Consider the distinction between joint surgery that reshapes or treats the joint and a reconstruction that replaces the condylar structure with a bone-and-cartilage graft.
What documentation supports 21242?
Document the condylar defect and its cause, the side treated, the reconstructive work, and use and source of the autogenous bone and cartilage graft.
How is bilateral reconstruction reported?
CMS identifies this as a bilateral procedure; reporting modifier 50 is paid at 150%. Document the work performed on each side.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, while team surgery is not permitted under the CMS facts for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
