Model the cost across the whole route, including the parts that are not the drug: consultation fees, laboratory monitoring, shipping, and the tests you will pay for yourself.
Features of a defensible telehealth intake: a real history including contraindications and family history, a recorded weight and height rather than a self-attested figure, baseline laboratory work or a documented reason for its absence, a named prescriber you can identify and verify, a titration plan, and a mechanism for reporting adverse events that reaches a clinician. A checkbox intake that issues a prescription in four minutes has none of these.
The internal-then-external appeal path is worth pursuing further than most people do, because the external reviewer is not the plan.
