What 27604 covers

An orthopedic or foot and ankle surgeon uses an incision to drain a bursa in the lower leg or ankle. The service is appropriate when the operative target is the bursa itself, rather than a separate soft-tissue lesion or the ankle joint. Documentation should identify the bursa and site, the reason open drainage was performed, and the operative work and findings.

Report this service for the bursal drainage, not for needle aspiration alone. The CMS global period is 90 days, including the day-before preoperative visit and related postoperative care 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 requires documented medical necessity; co-surgeons and team surgery are not permitted.

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.

27604 billing questions

How is this different from 27603?

Choose 27604 when the operative target is a bursa in the lower leg or ankle. Code 27603 describes drainage of a lower-leg lesion rather than a bursa.

Can needle aspiration of a bursa be reported as 27604?

No. 27604 describes operative incision and drainage; needle aspiration is a different service. Codes 20605 or 20610 may be relevant for aspiration or injection, depending on the bursa and site.

What should the operative note support?

Document the bursa and anatomic site, the indication for open drainage, and the incision, drainage, and operative findings. The record should make clear that the bursa, rather than an adjacent lesion or joint, was treated.

How does modifier 50 affect payment?

CMS identifies this as a bilateral procedure; reporting modifier 50 results in payment at 150%.

What are the assistant and global-surgery rules?

Assistant-at-surgery payment is allowed only when medical necessity is documented. The 90-day global period includes the day-before preoperative visit and related postoperative care; co-surgeons and team surgery are not permitted.

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.
