Look for the "Virtual care" badge on a profile, or filter by telehealth on the search page.

Generally no — state licensure rules require the clinician to be licensed in the state where the patient is physically located at the time of the visit. Some Illinois health systems hold licenses in neighboring states for cross-border care and telehealth; ask the office directly if you split time between Illinois and another state.
