What 27894 covers
This operation releases fascia in the leg to relieve pressure across the anterior, lateral, and posterior compartment regions. It is commonly performed by an orthopedic or trauma surgeon for acute compartment syndrome, including after a tibial injury, crush injury, or reperfusion. The procedure may be done in a hospital operating room when urgent surgical decompression is needed.
Choose this code when the operative report supports release of all three named compartment regions; select a sibling code when the documented release is limited to a different compartment pattern. Record the affected side and the compartments actually released, rather than relying on incision count alone. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral procedures, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose
- 27892Leg fasciotomy
- Choose 27892 when the operative report supports its narrower anterior and/or lateral compartment release pattern, rather than release across anterior, lateral, and posterior regions.
- 27893Leg fasciotomy
- Choose 27893 for the posterior compartment pattern described by that sibling code; use 27894 when anterior and lateral regions are also released.
- 27899Unlisted px leg/ankle
- Use 27899 only when the leg or ankle procedure is not represented by a specific listed code, rather than when the documented release matches 27894.
27894 billing questions
How does this differ from 27892 and 27893?
Use 27894 when the documented release involves anterior, lateral, and posterior compartment regions. Codes 27892 and 27893 describe narrower compartment patterns.
Does the number of incisions determine the code?
No. Base selection on the compartment regions actually decompressed and documented in the operative report, not the number of skin incisions.
How is bilateral leg decompression reported?
For bilateral procedures, report modifier 50; CMS pays this bilateral procedure at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. CMS does not permit co-surgeons or team surgery for this code.
