Summary & Overview
CPT 29445: Total Contact Walking Cast for Diabetic Foot Ulcer
CPT code 29445 denotes the application of a short leg total contact walking cast (TCC) used to offload and treat diabetic foot ulcers. This code captures a specialized, device-based therapeutic procedure that enables patients to ambulate while protecting and distributing pressure away from ulcerated areas. Nationally, the procedure is an important tool in diabetic wound management because it can reduce healing time, prevent complications, and lower the risk of lower-extremity amputation when used appropriately.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the use of a TCC, common settings where the service is delivered, and an overview of what to expect in payer coverage discussions.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with diabetes mellitus who presents to a podiatry or wound-care clinic for management of a non-healing plantar foot ulcer. The provider evaluates perfusion, infection signs, and offloading needs. After debridement and wound assessment, the clinician selects a total contact cast (TCC) to provide definitive offloading of the lower leg, ankle, and foot. The procedure is performed in an outpatient clinic, ambulatory surgery center, or hospital-based wound clinic. The TCC is molded to the patient’s limb and fitted to accept a removable cast shoe or is formed with an embedded footplate and rubber heel to permit protected weight-bearing. Typical workflow: history and focused exam, wound measurement and dressing change, debridement as needed, cast application (material selection, molding, padding), patient education on cast care and activity restrictions, and scheduling follow-up for cast change and wound reassessment. This procedure is billed using 29445 for application of a short leg walking or total contact cast for diabetic ulcer offloading.
