To assure that confidential records or information are protected, each reporting entity shall encrypt each of the following data elements in such a manner that each unique value for a data element produces an identical unique encrypted data element: Patient or enrollee identifier; and Internal subscriber contract number. In order to maintain a consistent and unique identifier for each patient across providers, payors, and services, the Commission shall: Provide selected data to the State-designed HIE for the creation and encryption of a Master Patient Index; and Include Master Patient Index identifiers received from the State-designated HIE in each eligibility data report submitted under Regulation .11 of this chapter. Each reporting entity shall maintain the security and preserve the confidentiality of the encrypted data.
