In the event that the signed authorization is not provided by the insured or the insured's authorized representative, if any, within 30 days of the receipt of the grievance, the carrier or utilization review organization may, in its discretion, issue a resolution of the grievance without review of some or all of the medical records.(3) The time limits in 958 CMR 3.305 may be waived or extended by mutual written agreement of the insured or the insured's authorized representative and the carrier. Any such agreement shall state the additional time limits, which shall not exceed 30 days from the date of the agreement.Amended by Mass Register Issue 1494, eff. 4/28/2023.
