Femur amputation is a major surgical procedure performed for various medical reasons, including trauma, vascular disease, tumors, or infections. Proper coding of these procedures is crucial for accurate billing and reimbursement. The Current Procedural Terminology (CPT) codes for femur amputation help healthcare providers classify and document these surgeries effectively.
This guide provides an in-depth look at the CPT codes for femur amputation, including coding guidelines, documentation requirements, surgical techniques, and post-operative care. Whether you’re a medical coder, surgeon, or healthcare administrator, this article will serve as a valuable resource.

CPT Code for Femur Amputation
Understanding Femur Amputation
Indications for Femur Amputation
Femur amputation may be required due to:
-
Severe trauma (e.g., crush injuries, gunshot wounds)
-
Peripheral vascular disease (e.g., diabetic gangrene)
-
Malignant tumors (e.g., osteosarcoma)
-
Chronic infections (e.g., osteomyelitis)
-
Congenital deformities
Types of Femur Amputations
The level of amputation depends on the patient’s condition and surgical goals:
| Amputation Type | Description |
|---|---|
| Above-Knee Amputation (AKA) | Removal of the femur above the knee joint |
| Below-Knee Amputation (BKA) | Removal below the knee, preserving the knee joint |
| Knee Disarticulation | Amputation through the knee joint |
| Hip Disarticulation | Removal of the entire femur at the hip joint |
CPT Codes for Femur Amputation
The American Medical Association (AMA) provides specific CPT codes for femur amputations:
| CPT Code | Description |
|---|---|
| 27590 | Amputation, thigh, through femur, any level |
| 27591 | Amputation, thigh, through femur, any level; re-amputation |
| 27592 | Disarticulation at knee |
| 27880 | Amputation, leg, through tibia and fibula; re-amputation |
| 27882 | Disarticulation at ankle (Syme’s amputation) |
Key Considerations for CPT Coding
-
27590 is used for primary above-knee amputations.
-
27591 applies to re-amputations (revising a previous amputation).
-
27592 is specific for knee disarticulation.
-
Hip disarticulation (27295) is coded separately if the entire femur is removed.
Coding Guidelines and Documentation
Proper documentation ensures accurate billing:
-
Operative report must specify the amputation level.
-
Medical necessity must be justified (e.g., gangrene, trauma).
-
Laterality (left or right) should be documented.
Modifiers and Reimbursement Considerations
Common modifiers used with femur amputation codes:
-
LT (Left side) / RT (Right side)
-
58 (Staged procedure)
-
22 (Increased procedural services)
Reimbursement varies by payer (Medicare, private insurance).
Surgical Techniques and Procedures
-
Preoperative Planning (Imaging, vascular assessment)
-
Incision and Soft Tissue Management
-
Bone Resection and Hemostasis
-
Wound Closure and Post-Op Care
Post-Amputation Care and Rehabilitation
-
Physical therapy for mobility training
-
Prosthetic fitting (if applicable)
-
Pain management (Phantom limb pain treatment)
Common Complications and Management
| Complication | Management |
|---|---|
| Infection | Antibiotics, wound care |
| Phantom limb pain | Medications, nerve blocks |
| Stump ulceration | Proper prosthetic fitting |
Frequently Asked Questions (FAQs)
1. What is the CPT code for a right above-knee amputation?
-
CPT 27590-RT
2. When is a re-amputation (CPT 27591) used?
-
When a previous amputation requires revision due to complications.
3. Does Medicare cover femur amputations?
-
Yes, if medically necessary (e.g., gangrene, non-healing ulcers).
Conclusion
Femur amputation CPT coding requires precision in documentation and adherence to AMA guidelines. Proper use of CPT 27590, 27591, and 27592 ensures accurate billing. Post-operative care and rehabilitation are crucial for patient recovery.
