What is a preauthorization number used for in a medical practice?

A preauthorization number is a critical aspect of the medical insurance process. It is obtained from the insurance company before a specific medical service or procedure is performed. This number indicates that the insurer has reviewed the requested service and has given approval for it, establishing that the procedure is covered under the patient's insurance policy.

When this number is entered into the practice management system, it helps streamline billing and ensures that the healthcare provider can expect reimbursement for the services rendered. It acts as a safeguard against potential denials by verifying that the treatment has been authorized by the insurance company in advance.

The other options do not accurately describe the purpose of a preauthorization number. Tracking patient visits pertains to scheduling and monitoring care rather than ensuring insurance approval. Documenting patient allergies is focused on patient safety and clinical care rather than financial authorization. Calculating patient fees relates to the financial aspect of billing but does not involve the insurance preauthorization process. Thus, the role of the preauthorization number is specifically tied to entering approved services into the system for billing and insurance purposes.
