In a follow up to last week’s question, then when is continuous overnight oximetry considered to be medically necessary?
For a limited group of private payers, continuous overnight oximetry is considered medically necessary when done for one of the following circumstances:
- The patient has a condition for which intermittent arterial blood gas sampling is likely to miss important variations (e.g., sleep apnea).
- The patient has a chronic condition resulting in hypoxemia, and there is a need to assess supplemental oxygen requirements and/or a therapeutic regimen.
