Mercy Hospital may decline Ms. Denton's request to amend her PHI based on which privacy rule provision?

The choice that states the history and physical was not created by Mercy Hospital is accurate because it aligns with privacy regulations concerning personal health information (PHI). According to the Health Insurance Portability and Accountability Act (HIPAA) and similar privacy regulations, entities are only required to amend records that they have created or maintained.

If the history and physical was created by another provider or institution, Mercy Hospital may decline the request to amend that information because they do not have ownership over the record in question. The regulations recognize the importance of ensuring that information is accurate and up-to-date, but they also delineate the responsibilities of the healthcare provider with respect to the information they are directly responsible for.

In this context, it is essential to understand the concept of a "designated record set," which is a group of records maintained by a covered entity that contains information used to make decisions about individuals. If the history and physical are not part of Mercy Hospital's designated record set – for instance, if they were created by a different hospital or physician outside of Mercy's jurisdiction – then it would be proper for the hospital to deny the amendment request. This provision ensures that amendments are only requested for records that the entity can accurately represent and modify.
