What 26863 covers

This add-on represents fusion of an additional interphalangeal joint of a finger using autogenous bone graft. Hand or orthopedic surgeons may perform it when more than one finger joint requires stabilization, such as for painful joint disease or deformity. The procedure is generally performed in an operating room; the operative report should identify the joints fused and document graft use.

Report 26863 with the primary grafted joint-fusion procedure, 26862, for each additional joint treated. The operative note should distinguish the primary joint from each additional joint and support the number of units billed. This code is an add-on, not a stand-alone service, and payment falls within the primary procedure’s global period.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

26863 billing questions

Which primary code must accompany 26863?

Report 26863 with 26862, the primary finger interphalangeal joint fusion code with autogenous graft. It is not reported by itself.

How many units should be reported?

Report one unit for each additional interphalangeal joint fused beyond the primary joint. The operative note should identify each joint treated.

When is 26861 a better fit?

Use 26861 for an additional interphalangeal joint fusion when the service does not include autogenous bone graft. Code 26863 is the grafted additional-joint counterpart.

Is graft harvesting separately represented by 26863?

The documentation should establish that autogenous graft was used for the additional joint. Report 26863 with 26862; payment is within the primary procedure’s global period.

What documentation supports reporting an additional joint?

The operative report should name the primary fused joint and each additional interphalangeal joint, describe the fusion performed, and support autogenous graft use.
