Medicare Data Requirements in California

California law requires that inpatient records contain the patient’s Medicare Identification number, if applicable.1  The medical records of any Medicare recipient are confidential and cannot be released without the written consent of the recipient or his or her representative.  However, the medical record may be released for statistical or summary data purposes if it has been de-identified.  Additionally the medical record may be exchanged between providers,  payers, or state or local agencies.2
