How to File a Health Insurance Complaint in Maryland

The Maryland Insurance Administration handles consumer complaints — here's how to file one.

If you have a dispute with your health insurance company in Maryland, the Maryland Insurance Administration (MIA) is the state agency that regulates insurers and handles consumer complaints. Filing a complaint is free and can be an effective tool for resolving disputes.

Maryland Insurance Administration

The MIA enforces Maryland insurance laws and investigates complaints against insurance companies licensed in the state. When you file a complaint, the MIA contacts your insurer on your behalf and requires a formal response.

How to File a Complaint in Maryland

  • Online: insurance.maryland.gov — use the Consumer Complaint portal
  • Phone: 1-800-492-6116
  • Mail: Maryland Insurance Administration, 200 St. Paul Place, Suite 2700, Baltimore, MD 21202

What to Include in Your Complaint

  • Your insurance policy number and carrier name
  • A clear description of the issue and timeline
  • Copies of denial letters, EOBs, or other relevant documents
  • Any correspondence with your insurer about the issue

What Happens After You File

The MIA will review your complaint and contact your insurer for a response. The insurer must respond within a specified timeframe. The MIA will notify you of the outcome and any action taken. Complaints are kept on record and contribute to the MIA's oversight of carrier behavior.

External Review in Maryland

Maryland also offers an independent external review process for denied claims. You can request external review through the MIA after exhausting your insurer's internal appeal process.
