What 95805 covers
A multiple sleep latency test uses repeated, scheduled daytime nap opportunities to assess how readily a patient falls asleep and whether sleep-onset features support a central hypersomnolence disorder such as narcolepsy. A sleep technologist typically conducts the recording in a sleep laboratory, and a qualified interpreting professional reviews the results and prepares the report. The test commonly follows an overnight attended polysomnography as part of an evaluation for persistent excessive daytime sleepiness.
Report 95805 for the daytime test, not for the preceding overnight study or for each nap opportunity separately. The record should support the clinical reason for testing and include the test findings and interpretation. CMS recognizes a professional component, reported with modifier 26, and a technical component, reported with modifier TC; reporting the code without a modifier represents the global service, including both components. CMS separately prices the 26 and TC services.

95805 billing questions
When is 95805 appropriate instead of an overnight sleep study?
Use 95805 for daytime nap testing of sleep propensity, often when evaluating persistent excessive sleepiness or suspected narcolepsy. An overnight polysomnography evaluates sleep during the night and may precede the MSLT.
Can the preceding polysomnography also be reported?
The overnight study and the daytime MSLT are distinct services. When both are performed, report the appropriate code for each documented test.
How are the professional and technical components reported?
Report modifier 26 for the professional interpretation and modifier TC for the technical service. Without either modifier, 95805 represents the global service.
Should a unit be reported for each nap opportunity?
No. Report the MSLT as the test service rather than billing each scheduled nap opportunity as a separate unit.
What documentation supports 95805?
Document the clinical indication for daytime sleepiness testing, the nap-test findings, and the interpreting professional's report. The record should distinguish the daytime MSLT from any overnight sleep study.
