New to helping someone in Massachusetts?

You do not need a law degree to help someone fight a health insurance denial. Start by gathering three basic documents:

  • Insurance card — shows which company administers the plan. Use the name and phone number on the card when you call or file paperwork (it may differ from an employer or clinic name).
  • Denial letter or explanation of benefits (EOB)— the notice that says a service was denied, not paid, or needs approval first. Look for appeal instructions and a deadline. On an EOB alone, search for words like "denied," "adverse determination," or "appeal."
  • Summary of Benefits and Coverage (SBC) — a plain-language summary of what the plan covers. It helps you tell whether the fight is about medical necessity or whether the benefit exists at all.

Your first tasks: identify what type of plan this is (Marketplace, job-based, Medicaid, Medicare) and write down the appeal deadline from the letter. Missing a deadline is one of the most common reasons people lose appeals they could have won.

Massachusetts plans often use terms like adverse determination or final adverse determination. You usually appeal first with the insurance company (internal grievance). If that fails, you may request external review through the Office of Patient Protection (OPP).

For steps that work in every state, read these general guides first, then return here for Massachusetts rules:

What is different in Massachusetts?

  • Massachusetts Health Connector: State Marketplace at MAhealthconnector.org. The insurer on your ID card handles prior authorization and grievances.
  • Prior authorization (c. 176O §§ 12, 25): Many initial utilization review decisions within 2 working days after complete information; failure to respond on designated PA forms within 2 business days can mean the request is deemed granted.
  • Internal grievances (§ 13): Written resolution often within 30 days; late grievances may be deemed resolved in your favor; expedited hospital, terminal illness, and urgent timelines apply.
  • OPP external review (§ 14): Request through OPP within 4 months of a final adverse determination; review panel decision often within 45 days standard or 72 hours expedited; binding on carrier and insured.
  • MassHealth (Medicaid MCO): MCO internal appeal first, then fair hearing with the Board of Hearings— separate from OPP commercial review.

Who is in charge of your plan?

The right agency depends on plan type. When in doubt, call member services and ask whether the plan is "fully insured in Massachusetts" or "self-funded ERISA."

  • Office of Patient Protection (OPP): External review and consumer assistance for many fully insured MA plans — masshpc.gov/opp. Hotline: 800-436-7757.
  • Division of Insurance (DOI): Regulates carriers, licensing, and consumer complaints — mass.gov — Division of Insurance. 877-563-4467.
  • U.S. Department of Labor: Many self-funded employer plans.
  • MassHealth / Board of Hearings: Medicaid appeals and fair hearings — How to appeal a MassHealth decision, Customer Service 800-841-2900.
  • CMS: Medicare and Medicare Advantage.

After appeals are exhausted, see Regulator complaints.
