What prior authorization is, and why requests get denied
Prior authorization, sometimes called preauthorization, is advance approval your health plan may require before you get certain care. Your doctor's office usually sends the request. The plan then decides whether it will cover the service.
A denial at this stage is a decision about a request, not a bill. No claim has been paid or refused yet, and you usually have time to respond. Reasons often include missing or incomplete information, a decision that the care is not medically necessary under the plan's rules, a service the plan does not cover, or a request that did not follow the plan's filing steps.
