Illinois insurance coverage notes

Coverage decisions depend on your specific plan, employer formulary, and prior-auth requirements.

Telehealth options for Illinois residents

Most major telehealth providers (Ro, Form Health, Hims) operate in Illinois. Specific telehealth rules — particularly for compounded semaglutide and tirzepatide — vary. Some compounded routes are unavailable in Illinois due to state-specific telehealth prescribing rules. Verify the provider lists Illinois as a service state before signing up.
