Final answer:
A patient must sign the authorization to release information form before an insurance claim can be processed, as required by HIPAA to protect their privacy rights.
Step-by-step explanation:
Before an insurance claim can be processed, a patient must sign the authorization to release information. The Health Insurance Portability and Accountability Act (HIPAA) requires health care providers and insurance companies to protect patient information and maintain strict confidentiality.
The patient's signature on an authorization form allows the necessary exchange of health information between these entities to file a claim. This process must occur without compromising the patient's privacy rights, which HIPAA safeguards.
It is not necessarily the insurance claim form itself, the HIPAA waiver form, or a referral form that needs to be signed, but rather the authorization form that permits the disclosure of information for billing purposes.
