Summary & Overview
HCPCS Level II E1390: Home Oxygen Concentrator, Single Delivery Port
HCPCS Level II code E1390 represents a home-use oxygen concentrator with a single delivery port capable of delivering at least 85% oxygen concentration at the prescribed flow rate. This equipment code identifies a stationary DME oxygen-delivery device commonly used for patients with hypoxemia or respiratory failure requiring continuous or intermittent supplemental oxygen in the home. Nationally, accurate coding of stationary oxygen concentrators affects coverage determinations, claims processing, and patient access to medically necessary oxygen therapy.
Major commercial payers commonly referenced for coverage and billing policies include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Readers will find in this publication a concise overview of the clinical context for E1390, how it relates to other oxygen supply codes, typical sites of service, common billing modifiers, and the ICD-10 diagnoses most frequently associated with claims for home oxygen concentrators. The content covers billing benchmarks, policy considerations that influence coverage and rentals versus purchase distinctions, and interoperability with oxygen contents and rental supply codes.
Data not available in the input for specific payer payment rates or state-specific coverage variations. The publication intends to clarify coding scope, typical use cases, and related service-line considerations for healthcare administrators, billing professionals, and payers.
Billing Code Overview
HCPCS Level II code E1390 describes an oxygen concentrator with a single delivery port that is capable of delivering 85 percent or greater oxygen concentration at the prescribed flow rate. This device is categorized as Durable Medical Equipment (DME) used for oxygen delivery and is intended primarily for use in the home (POS 12). The description focuses on the device's oxygen concentration capability and single-port delivery design as the defining clinical and equipment characteristics.
Clinical & Coding Specifications
Clinical Context
A home-dwelling adult patient with chronic hypoxemic respiratory failure is evaluated after pulse oximetry and arterial blood gas demonstrate persistent oxygen saturation below target on room air. A pulmonologist prescribes a stationary oxygen concentrator (single delivery port, >=85% oxygen concentration at prescribed flow) for domiciliary use. A durable medical equipment supplier arranges delivery and setup at the patient’s residence (POS 12), documents the prescription and necessity, and coordinates billing. Respiratory therapists provide education on device operation, safety, and troubleshooting; follow-up visits confirm adherence and oxygenation goals.
