What Is Prior Authorization
Prior authorization (PA) is a requirement by some insurance plans that a prescriber obtains approval before certain medications will be covered. The insurance company wants confirmation that the medication is medically necessary or that the patient meets specific criteria before they will pay for it.
When PAs Are Required
Insurance companies may require prior authorization for:
- Brand-name medications when generic alternatives exist
- Expensive specialty medications
- Medications used for off-label purposes
- Quantities exceeding standard limits
- Certain medication classes based on the plan's formulary
The Technician's Role
When a prescription is rejected at the point of sale due to a PA requirement, the pharmacy technician often identifies the rejection, notifies the patient of the delay, and initiates the PA process by contacting the prescriber's office. The technician may fax or electronically submit the PA request form to the prescriber, who then provides the clinical justification to the insurance company.
Processing Timeline
Prior authorizations can take anywhere from a few hours to several days depending on the insurance company and the complexity of the request. During this time, patients may need to wait for their medication or explore alternatives. Communicating realistic timelines to patients is an important part of managing expectations.
Exam Relevance
The PTCE may include questions about what triggers a prior authorization, the general process flow, and the roles of the technician, pharmacist, and prescriber in the PA process. Understanding PAs is part of the Order Entry and Processing domain.
