Summary & Overview
HCPCS E1356: Oxygen Accessory Battery Pack, Portable Concentrator
HCPCS Level II code E1356 designates a replacement battery pack or cartridge for portable oxygen concentrators. As a DME accessory code, E1356 matters nationally because it affects coverage and access to portable oxygen power solutions that enable patient mobility and continuity of oxygen therapy outside institutional settings. Reimbursement and coverage policies for replacement accessories can influence out-of-pocket costs and device usability for patients relying on portable concentrators.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise overview of the code’s clinical role, typical sites of service, and payer landscape. The publication covers benchmarking and reimbursement context, relevant policy updates affecting accessory coverage, and the clinical implications for ambulatory and home oxygen therapy. The report also summarizes common billing modifiers and procedural considerations for claims involving replacement components where data is available.
Data not available in the input for associated taxonomies, specific ICD-10 pairings, and related HCPCS codes is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is a person with chronic hypoxemic respiratory disease using a portable oxygen concentrator (POC). The POC battery pack or cartridge identified by E1356 is provided as a replacement accessory when the original battery is worn out, fails, or is needed as a spare for extended travel. The clinical workflow begins with a durable medical equipment (DME) supplier receiving a prescription from a treating clinician (pulmonologist, primary care physician, or home health physician) that documents the patient’s oxygen need and the device make/model. The supplier verifies device compatibility and patient eligibility, obtains prior authorization when required by the payer, documents device serial numbers and replacement rationale, and supplies the replacement battery pack/cartridge. Typical sites of service include the patient’s home, outpatient DME supplier locations, and inpatient discharge planning when arranging home oxygen. Common clinical scenarios include a patient with chronic obstructive pulmonary disease (COPD) who uses a POC for ambulation and requires a replacement battery prior to travel, or a patient whose existing battery no longer holds charge and needs a replacement to maintain prescribed oxygen use.
