Prior authorization denials can be appealed, and your doctor’s office is likely well-versed in how to respond to prior authorization denials. It could be that the health plan just needs additional or revised information and will approve the prior authorization request once they receive it. If the prior authorization request was for a medication, the health plan might want to use step therapy, which means they could potentially approve the medication if you first try a less expensive option and it doesn’t work. But it’s also possible that the health plan simply doesn’t cover the service in question, or that they continue to deny the request even on appeal. You can still obtain the service in that case, but with the understanding that your health plan won’t pay for it.
