What 27498 covers
A surgeon releases constricting fascia in the thigh or around the knee to relieve pressure within the affected area. This type of operation may be performed for acute compartment syndrome, including after trauma or another operation, in a hospital or other surgical facility. The operative report should identify the treated anatomy, the decompression performed, and the clinical reason for relieving pressure.
Report 27498 when the documented thigh or knee procedure matches this code’s specific service, rather than selecting a neighboring code from the brief descriptor alone. The record should make the treated site and operative work clear enough to distinguish this service from other compartment-decompression options. Medicare treats it as major surgery: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid, and co-surgeons are permitted; team surgery is not permitted.

27498 billing questions
How should 27498 be distinguished from 27496 or 27497?
All are in the thigh/knee decompression family. Compare the specific service documented in the operative report with each code’s full descriptor; the short CMS label alone does not establish the distinction.
What documentation supports reporting 27498?
Document the thigh or knee anatomy treated, the operative decompression performed, and the clinical reason for relieving pressure. The operative details should support this code rather than another option in the decompression family.
Does the Medicare global period include postoperative care?
Yes. The day-before preoperative visit and 90 days of related postoperative care are included in the major-surgery global period.
How does Medicare handle bilateral reporting?
When the procedure is performed bilaterally and reported with modifier 50, Medicare pays it at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid, and co-surgeons are permitted. Team surgery is not permitted for this code.
What happens if another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.
