What 27687 covers

This procedure lengthens or recesses the gastrocnemius aponeurosis to reduce calf tightness and improve ankle dorsiflexion. Foot and ankle surgeons commonly perform it for equinus contracture when the gastrocnemius limits motion, sometimes as part of treatment for related foot or ankle problems. A Strayer-type recession is a familiar example; this is distinct from lengthening the Achilles tendon.

Report the procedure when the operative work is a gastrocnemius recession, supported by the indication, examination findings, side, and details of the recession performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

How to choose

27685Tendon lengthening
Choose 27687 for a gastrocnemius recession. Code 27685 describes lengthening or shortening a single leg or ankle tendon more generally.
27686Tendon adjustment
Code 27686 concerns lengthening or shortening multiple leg or ankle tendons; 27687 identifies a gastrocnemius recession.
27690Tendon transfer
Code 27690 is for transferring or transplanting a tendon. It is not the code for releasing or lengthening the gastrocnemius aponeurosis.

27687 billing questions

How is this different from a general tendon lengthening?

This code is for a gastrocnemius recession. Use a general leg or ankle tendon-lengthening code when the operative work is lengthening a different tendon rather than recessing the gastrocnemius.

Does the code include Achilles tendon lengthening?

No. A gastrocnemius recession addresses tightness in the gastrocnemius aponeurosis; Achilles tendon lengthening is a different operative service.

What documentation supports the code?

Document the reason for surgery, the involved side, findings showing gastrocnemius tightness or equinus, and the operative technique and structures treated.

How is bilateral surgery reported?

CMS identifies this as a bilateral procedure. Reporting with modifier 50 is paid 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.
