Medical necessity must be established by demonstrating the patient's need for supplemental oxygen and the appropriateness of a non-heated system. This typically involves documentation of hypoxemia, respiratory distress, or other relevant clinical findings.

The supplier provides and sets up the oxygen and water vapor enriching system, ensuring proper function and instructing the patient on its use.They are responsible for ensuring the system is appropriate for the patient's needs and for providing necessary maintenance.

IMPORTANT:For oxygen delivery system with heated delivery, see E1405.

In simple words: This covers a system that adds moisture to the oxygen a patient breathes, without heating it. It’s for people who have trouble breathing and need extra oxygen.

This code represents the provision of an oxygen and water vapor enriching system that does not utilize a heated delivery mechanism.It is typically used for patients requiring supplemental oxygen who are unable to breathe sufficiently on their own, often due to severe respiratory or cardiac conditions.

Example 1: A patient with chronic obstructive pulmonary disease (COPD) requires supplemental oxygen at home and is prescribed a non-heated oxygen and water vapor enriching system., A patient with congestive heart failure experiences shortness of breath and is prescribed a portable oxygen system with a non-heated humidifier for use as needed., A patient recovering from pneumonia requires temporary oxygen therapy and is provided with a non-heated oxygen and water vapor enriching system for use during their recovery period.

Documentation should include the patient's diagnosis, the medical necessity for the oxygen and water vapor enriching system, the type of system provided (non-heated), and any patient education provided.
