Conn. Agencies Regs. § 19a-14-43
Nothing in these regulations shall prevent a practitioner from retaining records longer than the prescribed minimum. When medical records for a patient are retained by a health care facility or organization, the individual practitioner shall not be required to maintain duplicate records and the retention schedules of the facility or organization shall apply to the records. If a claim of malpractice, unprofessional conduct, or negligence with respect to a particular patient has been made, or if litigation has been commenced, then all records for that patient must be retained until the matter is resolved. A consulting health care provider need not retain records if they are sent to the referring provider, who must retain them. If a patient requests his records to be transferred to another provider who then becomes the primary provider to the patient, then the first provider is no longer required to retain that patient's records.
