Summary & Overview
HCPCS K0672: Lower Extremity Orthosis Removable Soft Interface, Replacement
HCPCS Level II code K0672 denotes a removable soft interface provided as an addition to a lower extremity orthosis, billed for replacement of all components on a per-item basis. This supply-level code matters nationally because replacement interfaces are a routine maintenance and patient comfort component of lower limb orthoses, affecting device longevity, clinical outcomes, and durable medical equipment (DME) spending patterns. Coverage and reimbursement policies for replacement parts like soft interfaces can influence patient access to properly functioning orthoses and the timely replacement of worn components.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of payer coverage considerations, common billing modifiers, and the clinical context for use of replacement soft interfaces. The publication summarizes benchmarks and policy themes relevant to DME replacement items, highlights documentation and billing elements associated with this HCPCS Level II code, and outlines common sites of service and service type implications. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with peripheral neuropathy and a history of diabetic foot ulcers presents to a durable medical equipment (DME) clinic for replacement of a worn removable soft interface (liner/padding) that fits inside a lower extremity orthosis (ankle-foot orthosis). The patient reports increased skin irritation and reduced orthosis comfort and compliance. The orthotist inspects the orthosis, documents wear and tear of the soft interface components, verifies prior authorization eligibility, and obtains measurements and photographs. The clinic submits a claim for replacement of the removable soft interface using billing code K0672, documents medical necessity tied to diagnoses (for example, neuropathy with ulceration or post-operative swelling), and dispenses the replacement interface after verifying fit and patient education. Follow-up is scheduled to confirm resolution of irritation and orthosis function.
