An authorization may NOT condition future medical treatment on the individual's approval because authorizations are for one treatment. Any additonal treatments must each have their own authorization. An authorization is NOT written in broad terms, because authorizations must have very specific terms to ensure that the patient does not recieve any unauthorized treatments.
An authorization is NOT needed for all purposes including those for treatment, payment, and operations. While authorizations are needed for treatment and operations, authorizations are not needed for payment purposes. So because of these details the correct answer is D.
Whenever a patient is being admitted to the hospital, he is asked to sign a pre-authorization. This has become more enforced since the HIPAA Privacy Act. The authorization is written in broad terms so that it covers things when the doctor, for instance, needs to tweak what he performs in the operating room.
The patient signs paperwork giving his authorization to have treatment, pay for the procedure(s)/operation, and give permission for the operation. In case it is needed, the authorization also gives the doctor permission for future medical treatment. Some of this is used to file with the insurance company and it is also following HIPAA rules of privacy. No one wants their personal information shared with just anyone; therefore, HIPAA rules of privacy protect the patient. The patient must give authority for any information to be released.
