Summary & Overview
HCPCS E1399: Durable Medical Equipment, Miscellaneous
HCPCS Level II code E1399 represents miscellaneous durable medical equipment (DME) items that lack a specific HCPCS code. Nationally, use of an unlisted DME code signals items or configurations that fall outside established code descriptors, which can affect claims processing, documentation requirements, and coverage determinations across payers. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical and billing role, typical sites of service where DME is furnished (home, outpatient clinics, DME suppliers), and the implications for billing and claims review when an unlisted DME code is used. The publication provides benchmarks where available, describes common payer policies and prior authorization practices, and summarizes documentation expectations that influence reimbursement and adjudication. It also outlines the broader policy context for unlisted DME coding and highlights areas where payers frequently request supplemental documentation or product-specific justification.

Clinical & Coding Specifications
Clinical Context
A patient with limited mobility due to advanced osteoarthritis and chronic lower-extremity neuropathy is evaluated in an outpatient durable medical equipment (DME) clinic. The patient has difficulty ambulating and requires a nonstandard assistive device component that does not have a specific HCPCS code. The clinician documents medical necessity, functional limitations, and prior conservative treatments. The DME supplier identifies a miscellaneous, non-routine accessory or custom adaptation that addresses gait stability and pressure relief. The supplier assigns E1399 for the item and submits documentation including the treating provider’s order, clinical notes, and supplier product description. Billing occurs from the supplier to the patient’s insurer (examples: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, Medicare) with appropriate modifiers added to reflect circumstances such as bilateral fitting, reduced services, or professional component if applicable. Prior authorization is obtained when required by the payor; delivery, patient education, and follow-up functional assessment are included in the service workflow.
