Summary & Overview
CPT 27886: Reamputation Below Knee Through Tibia and Fibula
CPT code 27886 denotes reamputation of the leg below the knee performed through the bones of the lower leg, typically undertaken for nonhealing stumps or persistent infection. This surgical procedure is clinically significant because it addresses complications of prior amputations that can lead to ongoing infection, prolonged disability, and increased resource use. Nationally, management of failed below-knee amputations influences inpatient surgical volumes and postoperative care needs across payers.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for reamputation, typical sites of service, and common billing considerations tied to CPT code 27886. The publication summarizes benchmarks in utilization and payment patterns where available, highlights policy and coverage considerations that affect access to reamputation, and clarifies procedural coding scope for clinical and billing teams.
The material provides a concise reference for clinicians, hospital billing staff, and policy analysts who need to understand how CPT code 27886 maps to clinical care pathways, resource implications, and payer coverage context at a national level. Data not available in the input will be identified as such in detailed sections.
Billing Code Overview
CPT code 27886 describes a reamputation of the leg below the knee performed through the tibia and fibula. The procedure is carried out when the original below-knee amputation stump fails to heal or when persistent infection necessitates surgical resection of additional bone and soft tissue.
Service Type: Surgical — Major Lower Extremity Amputation (below-knee reamputation)
Typical Site of Service: Inpatient surgical suite or hospital operating room, often requiring perioperative admission for infection management and postoperative care.
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with a history of peripheral arterial disease and prior transtibial (below-knee) amputation presents with a chronically nonhealing residual limb stump and recurrent deep infection despite serial wound care, antibiotics, and minor operative debridements. He reports persistent drainage, worsening pain, and an unstable residual bone edge that prevents safe prosthetic fitting. After multidisciplinary evaluation by the vascular surgery, orthopedics, infectious disease, and physical medicine teams, the decision is made to perform a reamputation through the tibia and fibula to revise the level of amputation, remove infected bone, and create a healthy, well-padded residual limb.
The clinical workflow includes preoperative optimization (vascular assessment, infection control, diabetes glycemic management, and prosthetic planning), informed consent documenting goals and risks, perioperative antibiotic prophylaxis or targeted therapy for active infection, operative reamputation of the stump through the lower-leg bones under general or regional anesthesia, intraoperative cultures and bone margins assessment, wound closure or staged flap coverage as indicated, postoperative pain control and physical therapy planning, and coordination for prosthetic fitting once healing is achieved. Typical documentation includes the operative report describing bone-level resection, neurovascular management, soft-tissue handling, implant or retained hardware status if present, and any intraoperative complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for 27886 (extensive debridement, prolonged operative time beyond typical complexity) and documentation supports increased work. |
23 | Unusual anesthesia | Use when general anesthesia is required for a procedure usually performed under local/monitored anesthesia due to unusual circumstances. |
52 | Reduced services | Use when a lesser procedure than 27886 is performed intentionally; document extent of reduction. |
53 | Discontinued procedure | Use when 27886 is started but halted due to extenuating circumstances or patient instability. |
59 | Distinct procedural service | Use when a separate, distinct procedure unrelated to the reamputation is performed on the same day and not typically bundled. |
62 | Two surgeons | Use when two surgeons from different specialties perform distinct portions of 27886 (for example, vascular and orthopedic co-surgery). |
63 | Procedure performed on infants less than 4 kg | Rarely used for 27886; include only if applicable to neonatal care. |
76 Not listed in provided modifiers — excluded per instructions. | --- | --- |
78 | Unplanned return to the operating room for a related procedure during the postoperative global period | Use if the patient requires an unplanned reoperation for issues related to the initial 27886 during the global period. |
79 | Unrelated procedure or service by the same physician during the postoperative period | Use when a distinct unrelated surgery is performed during the global period after 27886. |
LT | Left side | Use when the reamputation is on the left lower extremity. |
RT | Right side | Use when the reamputation is on the right lower extremity. |
GC | Service performed in part by a resident under the direction of a teaching physician | Use when a resident participates and teaching physician documents involvement per Medicare rules. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | Use when the anesthesiologist medically directs concurrent anesthesia services for 27886. |

2080P0206X | Orthopedic Surgery | Orthopedic surgeons commonly perform revision lower-extremity amputations and stump reconstruction. |
2084P0800X | Vascular Surgery | Vascular surgeons manage limb ischemia and may perform or co-manage reamputation when vascular disease contributes. |
207L00000X | Physical Medicine & Rehabilitation | PM&R physicians manage postoperative prosthetic planning, rehabilitation, and functional restoration. |
363A00000X | Infectious Disease | Infectious disease specialists guide perioperative and postoperative antimicrobial therapy for stump infections. |
207K00000X | General Surgery | General surgeons may perform lower-extremity amputations in some settings, particularly trauma or soft-tissue infection cases. |
