Mass. Gen. Laws ch. 176O, § 13
(iv) a resolution of a claim involving urgently needed services within 72 hours.
If the expedited review process affirms the denial of coverage or treatment, the carrier shall provide the insured, within 2 business days of the decision, including by any electronic means consented to by the insured: (1) a statement setting forth the specific medical and scientific reasons for denying coverage or treatment; (2) a description of alternative treatment, services or supplies covered or provided by the carrier, if any; (3) a description of the insured's rights to any further appeal; and (4) a description of the insured's right to request a conference. The carrier or utilization review organization shall schedule such a conference within ten days of receiving such a request from an insured, at which the information provided to the insured pursuant to clauses (1) and (2) shall be reviewed by the insured and a representative of the carrier who has authority to determine the disposition of the grievance. The carrier shall permit attendance at the conference of the insured, a designee of the insured or both, or, if the insured is a minor or incompetent, the parent, guardian or conservator of the insured as appropriate. The conference required by this paragraph shall be held within five business days if the treating physician determines, after consultation with the carrier's medical director or his designee, and based on standard medical practice, that the effectiveness of either the proposed treatment, services or supplies or any alternative treatment, services or supplies covered by the carrier, would be materially reduced if not provided at the earliest possible date.
