Which document is typically used to request pre-authorization for a service?

The pre-authorization form is a specific document designed for the purpose of requesting approval from an insurance company before a certain medical service, procedure, or medication is provided to a patient. This form includes important details such as the patient's information, the service being requested, relevant medical history, and sometimes supporting documentation from the healthcare provider. The insurance company reviews this information to determine whether the proposed service meets their coverage criteria and to ensure that it is medically necessary.

In health care billing and coding, understanding the necessity of pre-authorization is crucial, as many insurance plans require it to control costs and manage care. By successfully completing and submitting a pre-authorization form, healthcare providers can receive assurance or approval from the insurance carrier, allowing for the service to be conducted smoothly for the patient.

While an insurance card provides essential identification and access to coverage details, and the health history form contains the patient's medical history, neither directly serves the purpose of seeking pre-approval. A referral form is typically used to guide a patient to another health care provider but does not request authorization for services on its own. Thus, the pre-authorization form is the correct choice as it is explicitly designed for this process.
