What 27685 covers

An orthopedic or podiatric surgeon surgically lengthens or shortens one tendon in the leg or ankle to change its effective length. A familiar example is lengthening the Achilles tendon to address a fixed ankle or foot deformity associated with tendon contracture. The procedure is generally performed in an operating room or ambulatory surgery setting.

Select this code when the operative work changes the length of a single tendon; document the tendon treated, the side, the reason for changing its length, and the technique performed. For each additional tendon treated, 27686 is the related add-on code rather than another unit of 27685. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are reduced to 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

27685 billing questions

When should 27685 be selected instead of 27686?

Use 27685 for the first tendon whose length is changed. Report 27686 for each additional tendon treated in the same operative session.

Does this code describe tendon repair?

No. It describes surgically changing a tendon’s length. A repair code is considered when the operative work restores a torn or disrupted tendon rather than lengthening or shortening it.

What documentation supports reporting 27685?

The operative report should identify the tendon and side, the clinical reason for changing its length, and the lengthening or shortening work performed.

How is bilateral 27685 reported?

For bilateral procedures, report modifier 50. CMS pays the 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?

Assistant-at-surgery payment may be allowed. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
