In simple words: This code is for providing a machine that gives warm, moist oxygen to someone who can't breathe on their own.It helps them get the oxygen they need to breathe easier.

This HCPCS code, E1405, covers the supply of a heated oxygen and water vapor enriching delivery system.The system delivers oxygen to a patient who is unable to breathe independently, often due to severe respiratory or cardiac issues.The system typically includes a flow meter, oxygen tubing, a mask or other delivery device, and a humidifier. The oxygen concentrator uses naturally humidified, oxygen-rich air from room air, heats it, and delivers it via a face mask, nasal cannula, or other administration device. This code specifically represents a system with a heated delivery mechanism.

Example 1: A patient with chronic obstructive pulmonary disease (COPD) requiring supplemental oxygen at home is provided with a heated humidifier system to improve comfort and prevent airway irritation., A patient recovering from pneumonia needs oxygen support and benefits from the heated and humidified oxygen delivery to help loosen secretions and improve breathing., A patient with cystic fibrosis who experiences thick mucus production is prescribed a heated oxygen delivery system to help liquefy and remove secretions from the airways.

Documentation should include the patient's diagnosis justifying the need for oxygen therapy (e.g., COPD, pneumonia), the prescribed oxygen flow rate, and confirmation that the heated and humidified delivery system is medically necessary.Physician orders for the equipment and any related supplies should also be documented.

** Medicare coverage for this item requires medical necessity documentation and verification from the manufacturer that classifies this item as an oxygen and water vapor enriching system.
