For tests monitoring sleep latency or maintenance of wakefulness (MSLT/MWT), reports must include latency to NREM and REM, individual sub-test latencies, mean sleep latency, and number of REM occurrences on MSLT.

Polysomnography and sleep studies are covered for the diagnostic evaluation of suspected sleep disorders (including obstructive sleep apnea) and for assessment of response to therapies (e.g., CPAP) when performed with physician review, interpretation, and report.
Studies that include sleep staging (polysomnography) are covered when they meet the policy's recording and documentation requirements.
Diagnostic polysomnography or other sleep testing is covered when the patient has symptoms or complaints of one of the conditions listed in LCD L36839.
A single polysomnogram (PSG) with EEG is ordinarily sufficient and covered to evaluate and diagnose suspected obstructive sleep apnea (OSA).
