CPT 95810 is an overnight polysomnography in a sleep laboratory with a technologist present: sensors record breathing, oxygen, heart rhythm, brain activity and movement to diagnose sleep apnea and other sleep disorders. It is the traditional gold standard test, though home sleep tests (95806) have replaced it for many straightforward apnea cases.
What the price covers
The hospital's price is the technical fee for the sleep laboratory, the technologist and the recording equipment. The sleep physician's interpretation is billed separately. If CPAP is started during the same night (a split-night study, 95811), the code and price change.
Why prices vary
Attended sleep studies are among the most expensive routine diagnostic tests at hospitals, and prices vary several times within one area. Independent sleep centers are usually cheaper, and a home sleep test, when appropriate, costs a fraction of an in-lab study.
Questions to ask
- What is the self-pay price for 95810, and what does the interpretation add?
- Would a home sleep test (95806) be appropriate for me?
- If CPAP is started the same night, what does the study cost?
