Summary & Overview
CPT 28122: Resection of Infected Tarsal or Metatarsal Bone
CPT code 28122 designates surgical removal of infected portions of tarsal or metatarsal bones (excluding the talus and calcaneus) using craterization, saucerization, or diaphysectomy. This targeted bone resection is a clinically important option for managing focal osteomyelitis of the midfoot and forefoot and can impact patient outcomes, length of stay, and downstream resource use. Nationally, the code is used across inpatient and ambulatory surgical settings where operative debridement or partial bone resection is required.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for when CPT code 28122 is reported, typical sites of service, and the operational implications for surgical teams and facilities. The publication summarizes common modifiers and billing considerations provided in the input, and highlights bench-marking and policy-related topics readers can expect to review, such as payment alignment across major payers, documentation expectations for surgical bone debridement, and intersections with diagnosis coding strategies.
Data not available in the input for associated taxonomies, specific ICD-10 codes, and related procedure codes is noted where applicable. The content is intended for a national audience of clinicians, coders, and payer policy staff seeking concise, actionable information about reporting and contextual use of CPT code 28122.
Billing Code Overview
CPT code 28122 describes surgical removal of the infected portion of a tarsal or metatarsal bone (excluding the talus and calcaneus) using techniques such as craterization, saucerization, or diaphysectomy. This procedure is performed to eradicate osteomyelitic or otherwise infected bone segments in the midfoot and forefoot.
-
Service type: Surgical debridement/partial bone resection of tarsal or metatarsal bone
-
Typical site of service: Operating room or surgical suite in an ambulatory surgery center or hospital inpatient setting
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with poorly controlled diabetes presents with a chronic nonhealing plantar ulcer beneath the metatarsal heads. Imaging and clinical exam demonstrate focal osteomyelitis of the second metatarsal head with sequestrum formation and persistent purulent drainage despite prolonged antibiotics and local wound care. The orthopedic foot and ankle surgeon schedules operative management under regional or general anesthesia. In the operating room, after antiseptic prep and appropriate anesthesia, the surgeon performs incision and drainage of the soft-tissue infection, debrides necrotic tissue, and exposes the affected tarsal/metatarsal bone. The infected segment is removed using craterization/saucerization or limited diaphysectomy to eradicate sequestrum and establish healthy bleeding bone margins. Specimens are collected for culture and pathology. Hemostasis is achieved, the wound is irrigated, and closure or staged packing/negative-pressure wound therapy is applied depending on soft-tissue viability. Postoperative care includes targeted intravenous antibiotics guided by cultures, offloading or immobilization, and wound surveillance in outpatient or inpatient settings until healing. Typical site of service for this procedure is the operating room in an ambulatory surgery center or hospital inpatient/same-day surgical unit.
