HCPCS Code E0445: Oximeter Device for Measuring Blood Oxygen Levels Noninvasively

HCPCS code E0445 is assigned to an oximeter device used for noninvasive measurement of blood oxygen levels (pulse oximetry). This device monitors oxygen saturation in the arterial blood, typically through a sensor placed on the finger, toe, or earlobe, and is used for clinical and home monitoring purposes.

Yes, Medicare covers HCPCS code E0445, but coverage requires that medical necessity be established. It is typically used for continuous monitoring in situations where oxygen saturation levels are unpredictable or where acute therapeutic intervention is necessary. Proper documentation, including physician orders and clinical evidence, must support the use of the device. Coverage is often time-limited and subject to review.

HCPCS code E0424 refers to a stationary compressed gaseous oxygen system, rental. This code represents the rental of a complete stationary compressed gas system for home use and includes the container, oxygen contents, regulator, flowmeter, humidifier, nebulizer, cannula or mask, and necessary tubing. It is billed monthly and is used for patients requiring continuous oxygen therapy in a non-ambulatory setting.
