What 27590 covers

The surgeon removes the lower limb through the femur, with the level selected according to the extent of disease or injury and the tissue available for a residual limb. Typical cases include a limb rendered nonviable by advanced ischemia, extensive infection, major trauma, or a tumor requiring removal. These operations are generally performed in a hospital operating room by an orthopedic, vascular, or general surgeon, depending on the underlying condition.

Choose the code that matches the operative technique and closure: this code is distinct from the related thigh-amputation codes for primary closure or an open circular procedure. The operative report should identify the femoral level, indication, and closure approach. CMS assigns a 90-day global period, including 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 others at 50%. For bilateral procedures reported with modifier 50, CMS pays at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose

27591Thigh amputation
This code is for a thigh amputation with primary closure. Select it when primary closure is documented rather than reporting 27590.
27592Thigh amputation
This code describes an open, circular thigh amputation. The operative technique, not just the indication for amputation, distinguishes it from 27590.
27594Amputation revision
This code is for re-amputation through the femur. Use 27590 for the initial thigh amputation, not a subsequent re-amputation.
27598Leg amputation
This code describes amputation at the knee joint through the tibia and fibula. Code 27590 is for amputation through the femur.

27590 billing questions

How is this code distinguished from 27591?

Use the code that matches the documented closure approach. Code 27591 identifies thigh amputation with primary closure; this code does not describe that primary-closure variation.

When is 27592 a better fit?

Code 27592 describes an open, circular thigh amputation. Use this code when the operative report supports the standard thigh-amputation service rather than that open circular technique.

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. Co-surgeon payment requires supporting documentation, and CMS does not permit team surgery for this service.

How does CMS handle bilateral procedures and other procedures in the same session?

For a bilateral procedure reported with modifier 50, CMS pays at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%.

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.
