(a) General. Subject to the provisions governing medical records in § 401.55 and the provisions governing exempt systems in § 401.85, upon receipt of your request for notification of or access to a record and verification of your identity, we will review your request and grant notification or access to a record, if you are the subject of the record.
(b) Our delay in responding.
