Why prevention beats recovery
Every callback recovery is rework: someone has to get the VLS call or fax, find the prescriber, reauthorize or correct the Rx, resubmit, and re-communicate to the patient — and the patient's wait grows while this happens. The deeper problem is timing. When VLS only sees the prescription after it has been submitted by fax or EMR, the clinic discovers problems at the most inconvenient moment: the Rx is already out the door and the patient is expecting a compound.
Fizy Health moves that check forward. Cart validation inspects SIGs, prescriber state licensure, and stock before checkout, so the prescription that submits to the 503A partner is one it can compound without a callback. Recovery still exists for genuine compounder-side issues, but the volume of avoidable, self-inflicted callbacks — the kind that come from a fixable SIG or incomplete EMR notes — drops because the issue is caught before payment and submission.
