CPT 28126 Partial Toe Bone Resection Reimbursement | OpenPayer

Summary & Overview

CPT 28126: Partial Resection of Infected Toe Bone

CPT code 28126 denotes a surgical procedure involving removal of an infected portion of the toe bones (partial toe bone debridement/resection). This code is used when targeted excision of infected osseous tissue in the toe is required to manage localized osteomyelitis, reduce infection burden, and preserve function. Nationally, accurate coding for this procedure affects clinical documentation, care pathways for foot infections, and appropriate facility and professional reimbursement.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the service, typical sites of care, common billing considerations, and benchmarking information where available. The publication outlines expected documentation elements, typical service settings such as operating rooms and ambulatory surgery centers, and how this procedure fits within broader care for toe and foot infections.

This summary equips clinicians, coders, and policy analysts with a concise reference to the clinical purpose of CPT code 28126, the payer landscape covered in the analysis, and the types of benchmarks and policy-relevant details addressed in the full publication. Data not available in the input will be noted in relevant sections.

Billing Code Overview

CPT code 28126 describes a surgical procedure in which the provider removes the infected portion of the toe bones. This procedure is a partial toe bone debridement or resection performed to address localized bone infection, preserve surrounding healthy tissue, and reduce pain or risk of further spread.

Service type: Surgical debridement / partial bone resection
Typical site of service: Operating room, ambulatory surgery center, or procedure suite

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a progressively infected or osteomyelitic distal phalanx of a toe who presents to podiatry or orthopedic clinic after failed conservative care (oral antibiotics, local wound care). The patient often reports persistent pain, purulent drainage, and a nonhealing ulcer after peripheral trauma or diabetic neuropathy. Preoperative evaluation includes history and physical, focused vascular and neurologic exam of the foot, plain radiographs or MRI showing cortical bone destruction limited to toe phalanges, and optimization of comorbidities (for example diabetes mellitus, peripheral arterial disease). The procedure is performed in an ambulatory surgery center or hospital operating room under local, regional block, or general anesthesia depending on patient factors. Intraoperative steps include digital nerve block or ankle block, exposure of the affected phalanx, debridement of infected bone (partial or complete removal of affected distal toe bones), irrigation, possible culture of bone, and closure or secondary intention depending on soft tissue status. Postoperative care includes wound care, targeted antibiotics guided by cultures, pain control, and outpatient follow-up for wound healing and footwear modification. Complex cases may require multidisciplinary care involving infectious disease, vascular surgery, and wound care specialists.
