Maryland's Appeals and Grievance Law

You have the right to appeal denial decisions.

Maryland law gives Maryland consumers the right to appeal a decision that denies you coverage for medically necessary treatment. If your health care provider has determined that certain medical treatment is needed, but your HMO or health insurer does not agree, this law allows you to appeal. Under the appeals and grievances law, the Maryland Insurance Commissioner has the authority to overturn your health plan's decision if your treatment is determined to be medically necessary.

How the Appeals and Grievance Process Works

Step One

When an HMO or health insurer denies coverage for treatment, it must do so in writing. After an adverse decision or denial, your health plan must give you the details of its internal grievance process so that you can file an appeal with your health plan if you choose.

If you decide to file an appeal, the Maryland Attorney General's Health Education and Advocacy Unit will assist you, free-of-charge, in filing your appeal. The Health Education and Advocacy Unit may be reached toll-free at 1-877-261-8807.

Please note, if your complaint qualifies as an emergency, you do not have to file an appeal with the health plan before contacting the Maryland Insurance Administration.

Step Two

After you have exhausted your health plan's internal grievance process and if you are still not satisfied with the result, you or your authorized representative may seek assistance from the Maryland Insurance Administration within four months after your health plan's grievance decision. In its written decision, your health plan must provide details on filing a complaint with the Insurance Administration.

Please file your appeals and grievances complaint in writing (see How to File below) and provide copies of all documentation relevant to your case (e.g. denial letter from health plan, medical records, etc.). The Insurance Administration has medical experts who will review your case.

Once the Insurance Administration has concluded its investigation, you will be notified promptly of the final decision. In emergency cases, a decision must be provided within 24 hours.
