Yes, since tiers are assigned by office location, rather than by individual doctor. For example, Dr. Smithâ€s office in the city may be assigned to Tier 1 â€“ Preferred while the office in the suburbs may be assigned Tier 2 â€“ Enhanced. What you pay when you see Dr. Smith will be based on the tier of the office you visit for your appointment. This tier assignment will be displayed in our Find a Doctor tool. Learn more.
