- Typical setting: Sleep lab, home
- National avg charge (illustrative): $1,000–$4,000 (facility-based study; Medicare national rate approximately $400–$900 depending on component)

- Being billed for 95810 when the study was actually unattended (no technologist present overnight) — an unattended study should be coded 95806 at a significantly lower price.
