Health Billing & Insurance Complaints

The Health Education and Advocacy Unit (HEAU) helps Maryland consumers resolve billing disputes with healthcare providers and with private insurance coverage disputes. Our mediation services are free.

Note: All complaints submitted become public records subject to disclosure requests under state law. However, confidential information (financial, medical, psychological and sociological data) remains protected. Our full privacy policy can be found here.

Before You File

Before submitting a complaint to the Health Education and Advocacy Unit (HEAU), please review the information below. While the HEAU specializes in resolving health insurance disputes and medical billing issues, there are other resources better suited for certain types of complaints. To ensure your concern is addressed by the appropriate agency or program, please refer to the following guidelines:

  • Maryland Medicare beneficiaries who need help paying for their prescription drugs:
  • Assistance with Medicaid:
  • Cases involved in litigation: When consumers are represented by an attorney or there is active or past litigation, we cannot mediate the dispute.

  • If your issue is not listed above and involves a health insurance dispute, medical billing problem, or other health-related consumer matter, proceed with filing a complaint with the HEAU.

    What Happens Next

    When we receive a completed complaint, we will first review it to make sure that our office is the best agency to assist you. We may refer your complaint to a more appropriate agency. If we can assist you, our team will begin working to help resolve your dispute. We act as an impartial mediator between you and the healthcare provider or insurance company to find a fair solution.

    Complaint Review & Assessment

    • Initial Review: We assess whether our office is the appropriate agency to handle your healthcare complaint.
    • Assignment: Your case will be assigned to a supervisor who specializes in healthcare issues.
    • Contact Parties: Our mediator will contact both you and the healthcare entity to gather additional information.
    • Mediation Process: We work with both parties to negotiate a resolution to your issue.
    • Resolution: We'll keep you informed during the process and work to achieve a fair outcome.

    Complaint Review Timeline

    Resolution time varies based on case complexity and the responsiveness of the businesses involved. Simple billing issues may be resolved quickly, while complex issues may take longer.

    Complaints are handled in the order received and assignment times depend on current caseload or filing deadlines.

    If Mediation Is Unsuccessful

    If we cannot resolve your issue through mediation, we can provide information about additional options, which may include:

    • Filing a complaint with your insurance plan's regulatory agency
    • Information about private litigation options
