How it's built

Clinicians and clinics come from the federal NPI registry (NPPES), limited to Colorado practice locations and to types of care that see patients. Hospital-only roles such as emergency and anesthesia are left out.
Practice addresses come from CMS's Doctors and Clinicians file where it lists the clinician. Otherwise we show a street address only when an organization or several clinicians share it; a solo practice shows its town only.
A license shows as active only when the license number and last name both match an active Colorado license. Clinicians with an open board action are left out.
Insurance network labels come from dated checks of each insurance company's directory and from offices and Grove advisors. A check older than 45 days (November through January) or 100 days (the rest of the year) shows as not confirmed.

Sources

This is general information. It doesn't say a clinician is taking new patients or is in any plan's network unless a dated check says so. Confirm with the office and the insurance company before you book or enroll.
