What this is, in plain language
An overnight sleep recording done in a sleep lab to look for sleep apnea, abnormal movements, or other sleep disorders.
Why a clinician orders it
Loud snoring with witnessed apneas, severe daytime sleepiness, suspected complex sleep disorders, or when home testing is not appropriate.
Medical necessity — what insurers usually look at
Many plans (and Medicare LCDs) require an at-home sleep test first unless there is a documented reason an in-lab study is needed — significant cardiac/pulmonary disease, neuromuscular disease, suspected non-apnea sleep disorder, or an inconclusive home study.
Documentation to ask about
- ✓Symptoms and Epworth Sleepiness Scale or similar score
- ✓Reasons a home study is not appropriate
- ✓Other relevant medical conditions
Questions for your provider
- ?Has a home sleep test been considered?
- ?Will my plan cover an in-lab study, or do I need to start with home testing?
