The majority of prescriptions are handled asynchronously through the medical intake form your client fills out when ordering. This allows the clinician to evaluate whether a prescription is appropriate for the client based on their medical history, conditions, medications, and other factors.
Exceptions include:
A few states require a short clinician call before prescribing certain medications. This call will be completed at no extra cost.
Testosterone (TRT) always requires a video call (as well as a lab test) because it's a controlled substance.
There's no extra cost to your client for these calls.
