Specifies the source of payment for the healthcare services documented by electronic health records. To meet specific privacy policy needs, it is necessary to specify if the information protected by the rule was produced through public healthcare services or other type of insurance. [HL7 DAM] Note that the HL7 DAM contains two subclasses (Private Insurance and Public Services) to illustrate the type of security/privacy policies that are inherent from the healthcare payment source. Those two subclasses are examples of many potential kinds of policies, and would be fleshed out in the terminology referenced by the policyCategory code. The FHIM therefore does not model Private Insurance and Public Services as separate classes.
