What 27893 covers

This operation opens the deep fascia over the posterior compartment or compartments of the leg to relieve dangerous pressure and includes debridement of nonviable muscle and/or nerve. It is typically performed by an orthopedic or trauma surgeon in an operating room for acute compartment syndrome, such as after a severe leg injury or ischemic insult. The operative report should identify the posterior compartment work and document the devitalized tissue removed.

Choose this code when posterior compartment decompression includes that debridement; a posterior release without debridement is a different service. The preoperative day and 90 days of related postoperative care are included in the major-surgery global period. When other 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.

How to choose

27601Leg fasciotomy
Both involve posterior leg compartment decompression. Choose 27893 when nonviable muscle and/or nerve is debrided as part of the release; 27601 is the alternative without that debridement.
27892Leg fasciotomy
27892 is for anterior and/or lateral compartment decompression with debridement. 27893 is for posterior compartment or compartments.
27894Leg fasciotomy
27894 describes decompression of all leg compartments with debridement. Use 27893 for posterior compartment or compartments rather than all-compartment release.

27893 billing questions

How does this differ from 27601?

Use 27893 for posterior leg compartment decompression that includes debridement of nonviable muscle and/or nerve. Code 27601 describes posterior compartment decompression without that debridement.

Is the debridement separately reported?

The code includes debridement of nonviable muscle and/or nerve as part of the posterior compartment decompression. Do not separately report that same debridement as though it were a separate service.

What documentation supports choosing 27893?

Document the posterior compartment or compartments released and the nonviable muscle and/or nerve debrided. The operative report should make clear that the service was more than a decompression without debridement.

How is bilateral surgery reported?

Report bilateral performance with modifier 50; CMS pays the bilateral procedure at 150%.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
