What is prior authorization?
Prior authorization is a payer requirement that a provider obtain approval before delivering certain procedures, drugs, or services. The payer uses it to confirm that the service is covered under the plan and meets its criteria for medical necessity.
The provider submits clinical information ahead of the service, and the payer either approves, denies, or requests more detail. Until approval is granted, the payer may refuse to pay for the service.
Why is prior authorization critical for surgery centers?
Missing or incorrect prior authorization is one of the leading causes of denials at surgery centers, and a denial after the procedure has been performed can mean the work goes entirely unpaid. That makes securing authorization a high-stakes pre-service step.
For an ambulatory surgery center, verifying that every scheduled case has valid authorization before the day of surgery protects revenue and avoids putting patients in the middle of a coverage dispute. Diligence here prevents denials that are difficult or impossible to reverse later.
