About 27591: Thigh amputation with primary closure
Reports a through-femur thigh amputation closed primarily, typically for severe limb ischemia, infection, trauma, or disease requiring removal of the limb.
This service removes the lower limb through the femur and includes primary closure of the operative site. It may be performed by an orthopedic, vascular, or general surgeon, often in a hospital operating room for conditions such as advanced limb ischemia with gangrene, an unsalvageable traumatic injury, or extensive infection. The amputation level is through the thigh; a below-knee procedure is a different service.
Select this code when the operative documentation supports a thigh amputation with primary closure. The note should identify the level and side, the reason for amputation, and how the wound was managed. Medicare 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 is paid in full and others 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.

27591 billing questions
How does this differ from 27590?
Use 27591 when the thigh amputation is closed primarily. Code 27590 describes a thigh amputation without that primary-closure distinction.
When would 27592 be selected instead?
27592 is the sibling code for a thigh amputation with immediate prosthesis fitting. Primary closure alone supports 27591, not 27592.
Is primary closure separately reported?
Primary closure is the distinguishing feature of 27591 and is included in this service; it is not a separate amputation code.
How is bilateral reporting handled?
For bilateral thigh amputations in the same session, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided.
What documentation supports this code?
Document the amputation level through the femur, laterality, clinical reason, and primary closure of the operative site.
