Except as hereinafter provided, when a subpoena duces tecum is served upon a custodian of records of any hospital or physician's office duly licensed under the laws of this state in an action or proceeding in which the hospital or physician's office is neither a party nor the place where any cause of action is alleged to have arisen and such a subpoena requires the production of all or any part of the records of the hospital or physician's office related to the care or treatment of a patient in the hospital or physician's office, then it shall be sufficient compliance therewith if the custodian delivers, by hand or by registered mail to the court clerk or the officer, court reporter, body, or tribunal issuing the subpoena or conducting the hearing, a true and correct copy of all records described in the subpoena together with the affidavit described in § 16-46-305. However, a subpoena duces tecum for records shall not be deemed to include X-rays, electrocardiograms, and similar graphic matter unless they are specifically referred to in the subpoena.
