Material tradeoffs
- The quality and fit of care depend on the individual dietitian, their specialty, their schedule, and how well you work together.
- Insurance estimates can change after claims are processed. They do not guarantee what you will owe.
- Nutrition care and prescribing are separate professional scopes, and adding an AI assistant does not hand either scope to the assistant. Murph cannot match you with an RD, book or bill a visit, or provide medical nutrition therapy.
Common questions about Murph and Fay
How does Fay match you with a dietitian?
You filter dietitians by specialty, approach, availability, insurance, and virtual or in-person format. The ongoing relationship is with the RD or RDN you pick, not an interchangeable automated coach.
How much does a Fay nutrition visit cost?
Fay's estimates are based on your insurance and can be very low. Deductibles, eligibility, location, age, plan rules, and claim processing can change the final bill. Uncovered sessions are advertised at about $150.
Can a Fay dietitian prescribe weight loss medication?
Generally no. A Fay dietitian can provide medical nutrition therapy and work with you on eating needs related to a medication. Dietitians do not usually replace the clinician who prescribes, doses, or monitors a weight loss drug.
