    Clinical & Coding Specifications

    Clinical Context

    A home oxygen therapy patient uses a portable oxygen concentrator and reports that the DC power adapter for vehicle or off-grid use is lost or malfunctioning. The durable medical equipment (DME) supplier receives a replacement order for a DC power adapter that is billed as E1358 (Oxygen accessory, dc power adapter for portable concentrator, any type, replacement only, each). Typical workflow: clinician documents ongoing need for portable oxygen therapy (for example, chronic hypoxemia due to COPD or interstitial lung disease) and writes a DME order specifying replacement of the DC power adapter. The supplier verifies patient eligibility and the original concentrator make/model to ensure compatibility, obtains any required prior authorization from the payor, and dispenses the adapter. Billing is submitted by the DME supplier to the patient’s commercial or government payor using HCPCS code E1358. Typical site of service is the patient’s home or the supplier’s outpatient dispensing location; the accessory is used with a portable oxygen concentrator during travel, vehicle use, or when AC mains power is unavailable. Common clinical scenario: an established patient on long-term oxygen therapy (LTOT) traveling by automobile requires a replacement vehicle DC adapter after the original was damaged, and the adapter is provided as a non-routine replacement item billed under E1358.
