2025 HCPCS code E0433

Rental of a portable liquid oxygen system, including components for oxygen delivery.

Follow HCPCS coding guidelines for durable medical equipment (DME). Ensure that the documentation supports the medical necessity of the equipment and the specific system rented.

Modifiers may apply depending on the specific circumstances of the rental (e.g., modifiers for emergency situations or medically unnecessary upgrades).

Medical necessity for portable liquid oxygen therapy must be clearly documented. This typically involves evidence of hypoxemia (low blood oxygen levels) and the clinical justification for portable oxygen to maintain adequate oxygen saturation.Specific requirements for medical necessity documentation vary by payer.

The physician or other qualified healthcare provider is responsible for determining the medical necessity of the portable liquid oxygen system and documenting the patient's condition requiring oxygen therapy.The provider should also document the specific oxygen prescription and the patient's response to therapy.

This HCPCS code, E0433, represents the rental of a portable liquid oxygen system designed to convert gaseous oxygen into liquid form for patient use.The system includes a portable container, a regulator to control oxygen flow, a flowmeter for measuring the flow rate, a humidifier to prevent mucous membrane dryness, and a nasal cannula or mask with tubing for oxygen delivery.A supply reservoir and contents gauge may or may not be included.The system is typically used for home oxygen therapy and involves a home liquefier to refill portable containers.

Example 1: A patient with chronic obstructive pulmonary disease (COPD) requires supplemental oxygen at home. The physician prescribes portable liquid oxygen therapy, and the DME supplier provides and bills for the rental of the system using HCPCS code E0433., A patient with cystic fibrosis experiences periods of acute respiratory distress.The physician orders portable liquid oxygen for home use during these exacerbations. The DME supplier bills for the rental using code E0433., A patient recovering from pneumonia at home is experiencing low oxygen saturation levels. The physician orders temporary portable liquid oxygen therapy during recovery. The rental is billed with E0433.
