See what each visit includes

If you came from a service page, the visit type is already selected. If you're not sure, choose the doctor visit. Each type's price is in the list above.

  • Doctor visit: a new problem, virtual urgent care, primary care, children, birth control, STIs, skin and acne, visitors and chronic care.
  • Follow-up visit: a refill of a medicine you already take (non-controlled), or a review of your lab results from a previous visit with us.
  • School and university forms: the medical form your school or university asks for (when the video evaluation supports it), and a medical certificate of an illness or condition the doctor evaluated.
  • If your follow-up or forms visit turns out to need a full doctor visit, the doctor explains why and, with your consent, you pay the difference. See pricing.

Chest pain, trouble breathing, weakness on one side or bleeding that won’t stop? Don’t book: call 911 or go to the ER.

If it isn’t an emergency, instead of spending hours in an emergency room, talk to the doctor from home.
