HCPCS Level II code E0112 denotes a pair of wooden underarm (axillary) crutches, adjustable or fixed, supplied with pads, tips, and handgrips. As a common durable medical equipment (DME) item, this code is used to bill for basic mobility assistance devices that support ambulation following injury, surgery, or for chronic mobility limitations. Nationally, standardized coding for crutches helps ensure consistent coverage determinations, supplier billing, and claims processing across commercial payers and Medicare.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, explanations of billing relevance for suppliers and discharge planners, and a summary of what to expect in payer coverage policies and claims processing for basic underarm crutches. The publication highlights common billing considerations, typical documentation elements required by payers, and where to look for policy guidance. Data not available in the input for specific payer policy details, reimbursement rates, or associated ICD‑10 codes is noted as unavailable. The aim is to provide a clear, national‑level reference for clinicians, DME suppliers, and billing professionals handling claims involving HCPCS Level II code E0112.
