Designated record set includes which of the following?

• A. Records used in decision making and billing
• B. Only billing invoices
• C. The entire medical chart
• D. Records used in whole or in part to make decisions about the individual, including billing and sessions

Answer: (D)

Designated record set refers to the subset of a patient’s records that a covered entity uses to make decisions about the individual. This includes information from health care interactions and financial or administrative data that are used, in whole or in part, to determine care, eligibility, or payment. The best answer captures both clinical and administrative records that influence decisions—so records used in whole or in part to decide about the individual, including billing and sessions. It’s not limited to just billing invoices, and it’s not the entire medical chart; it’s specifically the records that are used to make decisions about the person.
