What is another name for a prior authorization number?

A prior authorization number is also commonly referred to as a certification number. This identifier is crucial in the healthcare billing process as it serves to confirm that the insurance provider has authorized a specific treatment or procedure before it is performed. This step is essential for ensuring reimbursement for the services provided, as it indicates that the patient's plan covers the treatment deemed medically necessary.

The other terms listed hold different meanings within healthcare billing and coding. A reference number typically acts as an identifier for various transactions or inquiries but does not specifically denote a prior authorization. A claim number is unique to individual claims submitted for services rendered, and a transaction number usually refers to specific records of transactions within an electronic billing system, neither of which directly correlate to the concept of prior authorization.
