Pre-authorization (Pre-auth)

Pre-authorization, also known as prior authorization, pre-determination, or pre-approval, is the process of submitting a proposed treatment plan to a dental insurance carrier for review and approval before the treatment is performed. The provider submits the request with supporting documentation such as radiographs, periodontal charts, photographs, or narrative clinical justifications. The carrier evaluates the request against the patient's plan benefits, clinical coverage criteria, and any applicable plan limitations to determine whether the proposed procedure is covered, at what level it will be reimbursed, and whether any conditions must be met before the service is delivered.

Common dental procedures that frequently require pre-authorization include crowns, bridges, implants, orthodontic treatment, periodontal surgery, endodontic retreatment, and some oral surgery procedures. The specific list of services requiring pre-auth varies by carrier and plan. The review process typically takes two to four weeks, during which the carrier may request additional documentation or refer the case to a dental consultant for clinical review. A pre-authorization approval provides a written confirmation of the expected coverage level, though most carriers include language stating that the approval is not a guarantee of payment and that final payment is subject to the patient's eligibility status at the time the service is performed.

For dental practices, managing pre-authorization requirements is a critical component of the billing workflow. Failing to obtain required pre-authorization before treatment is a leading cause of claim denials, and these denials are often non-recoverable because the carrier's policy requires the review to occur before the procedure, not after. Billing teams should maintain a reference of pre-authorization requirements by payer and procedure code, submit requests promptly after treatment planning, track pending approvals with expected response dates, and ensure that treatment is not scheduled until the pre-authorization is received. This proactive approach prevents costly denials and provides patients with confirmed cost estimates before they commit to treatment.
