CPT 28730: Midtarsal and Tarsometatarsal Joint Arthrodesis with Fixation

CPT code 28730 represents surgical immobilization (arthrodesis) of multiple or transverse midtarsal or tarsometatarsal (Lisfranc) joints using fixation devices. This midfoot procedure is clinically important for stabilizing complex fractures, Lisfranc injuries, and degenerative conditions that compromise foot alignment and weightbearing. Nationally, accurate coding for these procedures affects hospital and ambulatory surgical center billing, quality measurement, and comparative utilization analyses.

Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical indications and typical settings for service, guidance on common modifier use (listing provided in the input), and context for related procedural classification. The publication summarizes payer coverage patterns and benchmarking considerations where available and highlights policy or coding guidance updates that influence claims adjudication and documentation requirements.

The report is intended for clinicians, coding professionals, and policy analysts seeking a concise reference on procedure scope, service sites, and payer landscape for CPT code 28730. Data not available in the input is noted where relevant and omitted from specific tables.

Billing Code Overview

CPT code 28730 describes a surgical procedure to immobilize multiple or transverse midtarsal or tarsometatarsal (Lisfranc) joints using fixation devices. The procedure targets combined midtarsal joints (talus with navicular or calcaneus with cuboid) and tarsometatarsal joints (the cuneiforms and cuboid with the metatarsal bases).

Service type: Surgical fixation/arthrodesis of multiple midfoot or tarsometatarsal joints.

Typical site of service: Hospital inpatient or outpatient operating room, or ambulatory surgical center, depending on patient condition and complexity.

Clinical & Coding Specifications

Clinical Context

A typical patient is a 45–65-year-old adult presenting with midfoot pain, deformity, and instability after a traumatic injury (for example, a high-energy motor vehicle collision or a twisting injury) or chronic degenerative collapse (such as progressive midfoot arthritis or diabetic Charcot arthropathy). Evaluation includes history, physical exam noting midtarsal or tarsometatarsal (Lisfranc) joint instability, weight-bearing radiographs, CT or MRI to define joint displacement and articular damage, and preoperative medical clearance.

The clinical workflow: the patient is consented for surgical fusion of multiple or transverse midtarsal or tarsometatarsal joints (CPT 28730). Preoperative planning identifies which joints require fixation and selection of hardware (plates, screws, or intramedullary devices). The procedure is typically performed in an operating room under regional or general anesthesia with fluoroscopic guidance. Postoperative care includes immobilization in a cast or boot, non‑weightbearing for an appropriate interval, serial radiographs to confirm fusion, and physical therapy once fusion is established. The typical site of service is an ambulatory surgery center or hospital operating room. This procedure is performed by orthopedic foot and ankle surgeons or podiatric surgeons with operative privileges for joint arthrodesis.

Coding Specifications
