What 21116 covers

This service places contrast material into a temporomandibular joint so radiographic imaging can outline the joint space and help assess internal derangement, such as suspected disc-related dysfunction. It is generally performed by a radiologist or an oral and maxillofacial surgeon in an imaging suite or equipped office, with the injection and arthrographic imaging interpreted as part of the service. Clinical use may follow persistent joint pain, clicking, or restricted jaw movement when an arthrogram is selected to investigate an intra-articular problem.

Report 21116 for the joint arthrography procedure, documenting the indication, side, contrast injection, and resulting images or findings. Same-day preoperative and postoperative care is included under its 0-day global period. When this and other procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. For bilateral work, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

How to choose

70332TMJ imaging
This code describes radiographic examination of TMJ arthrography. Code 21116 describes the contrast-injection procedure and includes its radiographic supervision and interpretation.
70330TMJ X-ray
Use 70330 for bilateral TMJ radiographs without an arthrographic contrast injection; use 21116 when the joint is injected for arthrography.
70336Jaw joint MRI
70336 describes MRI of the temporomandibular joint or joints. It is a different imaging method from the contrast-injection arthrography represented by 21116.

21116 billing questions

When should 21116 be chosen instead of plain TMJ radiographs?

Use 21116 when contrast is injected into the joint for arthrographic evaluation. Plain TMJ radiographs, such as 70328 or 70330, do not describe that contrast-injection procedure.

Does 21116 include the arthrographic imaging?

The service includes radiographic supervision and interpretation associated with the TMJ arthrography. Document the injection and the resulting images or findings; do not assume the same arthrogram imaging is separately reportable.

How is bilateral TMJ work reported?

For bilateral work, report modifier 50; CMS pays the bilateral procedure at 150%.

What happens when 21116 is performed with other procedures in the same session?

The highest-valued procedure is paid in full, and the other procedures are subject to the standard 50% multiple-procedure reduction.

Can an assistant or co-surgeon be reported for 21116?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
