Summary & Overview
CPT 25905: Circumferential Forearm Transection for Infection Control
CPT code 25905 denotes a circumferential forearm procedure in which the provider completely transects the radius and ulna by running a cutting instrument around the bones and cutting through them. The code captures a major surgical intervention typically performed to control severe infection or to manage nonviable limbs. Nationally, this code represents high-acuity surgical care with significant implications for hospital resource use, postoperative care needs, and coding precision.
Key payers examined in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the service type. The publication also summarizes payer coverage considerations and commonly reported modifiers associated with high-acuity surgical procedures when data is available. Additionally, the report outlines benchmarks and policy updates relevant to billing and reimbursement for major limb procedures, and it highlights documentation elements that support correct code selection.
This summary is intended for coding professionals, surgical departments, and payer policy teams seeking a national-level overview of CPT code 25905 and its clinical and administrative relevance.
Billing Code Overview
CPT code 25905 describes a surgical procedure in which the provider completely cuts through the forearm by running a cutting instrument around the radius and ulna in a circular motion and then transecting the bones. The procedure is commonly performed to control infection or to manage a severely compromised limb when preservation is not possible.
-
Service type: Surgical amputation / limb salvage procedure
-
Typical site of service: Operating room or surgical suite in an inpatient or outpatient hospital setting
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a forearm limb-threatening infection (eg, severe osteomyelitis, necrotizing soft tissue infection, or uncontrolled sepsis localized to the forearm) who has failed conservative therapy including antibiotics and debridement. The patient presents with escalating pain, purulent drainage, systemic inflammatory response, and radiographic or clinical evidence that the infection involves the radius and ulna with nonviable tissue. After multidisciplinary evaluation (orthopedic surgery, trauma, infectious disease, and anesthesia), the decision is made to perform a transradial/transulnar completion amputation of the forearm by circular osteotomy to control infection and prevent systemic spread.
Preoperative workflow includes informed consent, documentation of indication and limb salvage attempts, vascular and neurologic assessment, anesthesia evaluation, and antibiotic prophylaxis as appropriate. Intraoperative workflow includes tourniquet use as indicated, circular bone cuts around the radius and ulna at the planned level, soft-tissue management, possible nerve handling for pain control, and primary or delayed wound closure depending on contamination. Postoperative workflow includes monitoring for hemodynamic stability, pain control, wound care, antibiotic management guided by cultures, occupational/physical therapy planning, and documentation of the operative report with exact level of amputation, findings, and personnel.
