What 27601 covers

This operation releases the fascia surrounding the posterior compartment or compartments of the lower leg to relieve dangerous tissue pressure. Orthopedic and trauma surgeons commonly perform it urgently for compartment syndrome after injuries such as fractures or crush trauma. The operative note should identify the leg, the compartments released, and the findings that prompted decompression.

Report this code when the documented release is limited to the posterior compartment or compartments; release that also includes anterior or lateral compartments follows a different code in the family. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are paid at 50%. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
