E1390
Oxygen Concentrator, Single Delivery Port
Code Description
HCPCS code E1390 is used to report a stationary oxygen concentrator with a single delivery port that is capable of delivering 85% or greater oxygen concentration at the prescribed flow rate. Oxygen concentrators are commonly prescribed for home oxygen therapy in patients with chronic respiratory conditions that cause hypoxemia.
When to Use E1390
Common examples include:
Chronic obstructive pulmonary disease (COPD)
Chronic hypoxemia
Home oxygen therapy
Interstitial lung disease
Pulmonary fibrosis
Severe chronic respiratory disease
Long-term oxygen therapy prescribed by a physician
Documentation Requirements
Documentation should include:
Medical necessity for oxygen therapy
Physician's written order
Qualifying oxygen saturation or arterial blood gas (ABG) results
Patient diagnosis
Confirmation that the oxygen concentrator was provided
Complete medical record
Examples
Example 1
A patient with severe COPD has documented chronic hypoxemia confirmed by pulse oximetry and arterial blood gas testing. The physician prescribes a stationary oxygen concentrator for continuous home oxygen therapy. HCPCS code E1390 is reported for the oxygen concentrator.
Example 2
A patient with pulmonary fibrosis experiences persistent low oxygen levels despite medical treatment. After meeting coverage criteria, a durable medical equipment supplier furnishes a stationary single-port oxygen concentrator for home use, making HCPCS code E1390 the appropriate code.
Common Billing Mistakes
Common billing mistakes include:
Billing without documentation supporting medical necessity
Missing qualifying oxygen testing results
Reporting the incorrect oxygen equipment code
Failing to maintain required physician documentation
Duplicate billing for the same equipment
