History/Background and/or General Information

Pulse oximetry provides a simple, accurate, and noninvasive technique for the continuous or intermittent monitoring of arterial oxygen saturation. A small lightweight device attaches to the finger or toe and directs through the nailbed two wavelengths of light; a photodetector measures absorption. Arterial pulsation is used to gate the signal to the arterial component of blood contained within the nailbed.

Ear oximetry is a noninvasive method for evaluating arterial oxygenation. Ear oximeters are commonly used in sleep studies.

Covered Indications

Single and Multiple Determinations of oxygen saturation:

Ear or pulse oximetry for oxygen saturation will be considered medically necessary when the patient has a condition resulting in hypoxemia and there is a need to assess the status of a chronic respiratory condition, supplemental oxygen requirements and/or a therapeutic regimen.

Continuous Overnight Monitoring of oxygen saturation:

Ear or pulse oximetry for oxygen saturation by continuous overnight monitoring will be considered medically necessary in the following circumstances:

• The patient must have a condition for which intermittent arterial blood gas sampling is likely to miss important variations, and
• The patient must have a condition resulting in hypoxemia and there is a need to assess supplemental oxygen requirements and/or a therapeutic regimen.

Limitations

As published in the CMS IOM Publication 100-08, Medicare Program Integrity Manual, Chapter 13, Section 13.5.4, an item or service may be covered by a contractor LCD if it is reasonable and necessary under the Social Security Act Section 1862 (a)(1)(A).
