Orthopedic surgery

About 23931: Incision and drainage of elbow bursa

Reports surgical opening and drainage of an upper arm or elbow bursa, such as an infected olecranon bursa requiring drainage.

This procedure opens an upper arm or elbow bursa and drains its contents, typically to treat a bursal collection such as septic olecranon bursitis. An orthopedic or other qualified physician may perform it in an office or facility setting when drainage through an incision is needed rather than needle aspiration alone. The operative record should identify the bursa and side, describe the collection and drainage performed, and support why an incision was required.

Choose this code for drainage of the bursa itself, not for a separate deep abscess or hematoma in the upper arm or elbow. Documentation should distinguish the bursal target from surrounding soft tissue and record laterality. The procedure has a 10-day global period, which includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

23931 billing questions

How is 23931 distinguished from drainage of an upper arm or elbow abscess?

Use 23931 when the incision and drainage target is a bursa. Code 23930 is for a deep abscess or hematoma in the upper arm or elbow.

Does needle aspiration of an elbow bursa qualify for 23931?

No. 23931 describes surgical incision and drainage; aspiration of an intermediate joint or bursa is represented by a different service.

Can modifier 50 be used for bilateral bursal drainage?

Yes. CMS lists this as a bilateral procedure, and modifier 50 is paid at 150%.

Are related postoperative visits separately paid during the global period?

Related postoperative visits for 10 days are included in the minor-procedure global period.

Can an assistant or co-surgeon be reported for this procedure?

Assistant-at-surgery payment is subject to a statutory restriction. Co-surgeons and team surgery are not permitted.

What documentation supports reporting 23931?

Document the specific bursa and side, the bursal collection, and the incision and drainage performed. The record should make clear that the target was the bursa rather than adjacent soft tissue.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
