Hawaii Revised Statutes Division 4. Courts and Judicial Proceedings § 622-52

(a) Whenever a subpoena duces tecum is served upon the custodian of medical records or other qualified witness from a medical facility, in an action or other proceeding on a claim for personal injuries in which the custodian or the custodian's employer is neither a party to the action or proceeding nor is it alleged that the claim arose at the medical facility, and such subpoena requires the production in court, or before an officer, board, commission, or tribunal, of all or any part of the medical records of a patient who is or has been cared for or treated at the medical facility, it shall be sufficient compliance therewith if the custodian or other qualified witness within five days after receipt of such subpoena, delivers by registered or certified mail or by messenger a true and correct copy (which may be by any method described in rule 1001(4), Hawaii rules of evidence) of all the medical records described in such subpoena to the clerk of the court or the clerk's deputy authorized to issue it, together with the affidavit described in section 622-53.

(b) The copy of the medical records shall be separately enclosed in an inner envelope or wrapper, sealed, with the title and number of the action, name of the custodian or other qualified witness, and date of the subpoena clearly inscribed thereon; the sealed envelope or wrapper shall then be enclosed in an outer envelope or wrapper, sealed, and directed as follows:

(c) The copy of the medical records shall remain sealed and shall be opened only at the time of trial, or other hearing, upon the direction of the judge, officer, board, commission, or tribunal conducting the proceeding, in the presence of all parties who have appeared in person or by counsel at such trial, or hearing, unless the parties or counsel in the proceeding otherwise agree, or unless the sealed envelope or wrapper is returned to the custodian or other qualified witness who is to appear personally. Copies of medical records which are not introduced in evidence or required as part of the record shall be returned by registered or certified mail or by messenger to the person or entity from whom received. If the copies of the medical records are introduced in evidence or are required as part of the record, they shall be returned by registered or certified mail or messenger to the person or entity from whom received as soon as their use is no longer needed, after the trial, or other hearing.
