What is CPT Code E1390?
CPT E1390 is defined as: A stationary oxygen concentrator, which is an electrically powered device that separates oxygen from ambient air and delivers it through a single delivery port. The device must be capable of delivering a concentration of 85% or greater at the prescribed flow rate. It is intended for long-term home oxygen therapy for patients with chronic respiratory conditions.
This code is primarily used for Labs services. It falls under the category of Durable Medical Equipment (DME) and is valid for the 2026 calendar year according to the CMS Physician Fee Schedule.
