The Details of Filing An Insurance Complaint

What you need for Filing An Insurance Complaint

If your complaint involves ongoing litigation, do not complete this form. Consumer Services is not authorized to render legal opinions and does not intervene between attorneys and their clients, nor do we perform work on behalf of attorneys. 

Before submitting your complaint:

Our ability to assist you requires your cooperation. In order to process your complaint, we need the following information from you:

  • Name of the insurance companies and agents involved
  • Your policy and/or claim numbers as well as the names and phone numbers of the people you have been dealing with.

Please be sure to send us all relevant information when you submit your complaint. If you need to send more documents or a longer summary than the form allows, please email the information to and note that you filed a complaint and are providing additional documentation.  Please be aware that Consumer Services will send a copy of your complaint and any related materials to any company, agent or licensee involved in this matter. Please do not send any medical records.

What happens after you submit your complaint?

All complaints and information requests are reviewed upon receipt to ensure that they are within the jurisdiction of the DOI. If jurisdiction is identified, you (the complainant) will receive a written acknowledgement of the complaint or an email or letter indicating that the complaint was incomplete and requesting any required, missing information or documents. The respondent (the insurance company or agent you filed a complaint about) will receive written notification that a complaint has been filed along with a copy of your complaint and the supporting documentation. The respondent has 30 days to provide a written response to the complaint. The complaint is then assigned to a CSU examiner for review.

    Consumer Services can only help you obtain rights and benefits that you are entitled to under your insurance contract and the Massachusetts insurance laws. We help consumers determine if we have any jurisdiction, and if not, let them know where help might be found.

    • If your complaint involves a workers' compensation claim, please contact the Division of Industrial Accidents.
    • If your complaint is regarding your health insurance, you should be aware that some health plans are self-funded (aka self-insured) plans and are regulated by the federal government, not the Division of Insurance. The benefits coordinator at your place of employment can tell you what kind of health plan you are in and direct you to the appropriate source of help. 
    • If your complaint concerns a medical necessity denial, you should file a complaint with the Office of Patient Protection.
