What 27105 covers

The surgeon mobilizes and repositions a spinal-region muscle to improve hip mechanics. A familiar application is using the gluteus maximus to help restore abductor function when the usual hip abductors are deficient. Orthopedic surgeons typically perform the operation in a hospital or other surgical facility; the operative report should identify the transferred muscle, its new attachment, the hip side, and the condition being treated.

Select this code when the transferred muscle is the spinal-muscle type, rather than an abdominal or iliopsoas muscle. The operative details should support the donor muscle and transfer performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose

27100Muscle transfer
27100 describes transfer of an abdominal muscle. Use 27105 when the transferred muscle is the spinal-muscle type.
27110Iliopsoas transfer
27110 is for iliopsoas transfer. The donor muscle, not simply the goal of improving hip function, separates it from 27105.
27111Muscle transfer
27111 describes iliopsoas transfer with tendon lengthening. It is not the spinal-muscle transfer reported with 27105.

27105 billing questions

How is this distinguished from an iliopsoas transfer?

Choose this code when the transferred muscle is a spinal-region muscle. Iliopsoas transfer is reported with 27110 or 27111, depending on whether tendon lengthening is performed.

What documentation supports the code?

The operative report should identify the muscle moved, its donor and recipient attachments, the side treated, and the reason for the transfer. For a gluteus maximus transfer, document the hip abductor problem being addressed.

Does the code include postoperative visits?

Yes. Medicare's 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

How is bilateral surgery reported?

For bilateral procedures, report modifier 50; CMS pays this code at 150% under the stated bilateral rule.

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.
