What document should an MAA check for accuracy against a patient’s demographic form?

The correct choice is to check the driver's license for accuracy against a patient’s demographic form. The driver's license is an official government-issued identification that contains crucial personal information, such as the patient’s full name, date of birth, and address. By comparing the demographic form to the driver's license, the Medical Administrative Assistant can ensure that the information the patient has provided is accurate and up to date.

This verification is essential for maintaining accurate medical records, ensuring proper patient identification, and facilitating communication with insurance companies when processing claims. Accurate demographic information prevents potential confusion or errors in patient care and billing, making the driver’s license a reliable source for validation.

The other options, while important in various aspects of patient care and administration, do not serve as effective verification tools for basic demographic information. The medical history form provides background on a patient's health but won't help confirm their demographic details. The authorization for treatment is a consent form that documents patient agreement for medical procedures and does not include demographic data. Lastly, the assignment of benefits relates to insurance payments and doesn't have any personal identification information necessary for checking the accuracy of demographics.
