What 23930 covers

Code 23930 covers operative opening and evacuation of a deep abscess or hematoma in the upper arm or elbow region. An orthopedic or other surgeon typically performs it when the collection lies beyond a superficial skin or subcutaneous pocket and requires deeper exposure for drainage. The procedure may take place in an operating room or, when appropriate, an office procedure room. The target is a deep collection, not an elbow bursa.

Report the service for the documented drainage, specifying the side and region, the collection and its depth, and the work performed to expose and evacuate it. Documentation should distinguish a deep collection from a skin-level abscess or bursal process. CMS assigns a 10-day minor-procedure global period, including related postoperative visits during that period. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral performance with modifier 50 is paid at 150%. An assistant at surgery is not paid; co-surgeons and team surgery are not permitted.

23930 billing questions

How does this differ from drainage of an elbow bursa?

Use 23930 for a deep abscess or hematoma in the upper arm or elbow region. A collection specifically involving the bursa is described by 23931.

Can this code be used for a superficial skin abscess?

No. For a simple skin or subcutaneous abscess, consider 10060; 23930 is for a deep collection in the upper arm or elbow area.

What documentation supports reporting 23930?

Document the anatomical region and side, whether the target is an abscess or hematoma, its depth, and the operative exposure and drainage performed.

Are related postoperative visits separately included?

CMS assigns this procedure a 10-day global period. Related postoperative visits during those 10 days are included.

How does Medicare handle bilateral reporting and assistants?

CMS pays bilateral performance reported with modifier 50 at 150%. An assistant at surgery is not paid, and co-surgeons and team surgery are not permitted.

What happens when another procedure is performed in the same session?

CMS pays the highest-valued procedure in full and pays the other procedures at 50% when multiple procedures are performed in the same session.

Where these rates come from

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.
