The Details   of Filing An Insurance Complaint

What you need   for Filing An Insurance Complaint

If your complaint involves ongoing litigation or if you have an attorney representing you, 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. Please see below for more information on what we can and cannot do.

If you have already filed a complaint about a particular issue and would like an update on your complaint, please call our Hotline or email us.

Before submitting your complaint:

Before filing a complaint, please make sure you have considered your other options:

  • Have you contacted your agent for assistance?
  • Have you contacted the company for assistance?
  • Have you sent the insurance company the information they requested?
  • Have you asked the company to explain the reason for not paying your claim?

Your completed complaint form gives us authorization to review your concerns and provides the information necessary to pursue our investigation. In order to process your complaint, we also need the following information from you:

  • Name of the insurance companies and agents involved
  • Your Member ID, policy and/or claim numbers
  • A signed and notarized Power of Attorney (POA) if you are filing on behalf of a family member.


Please be sure to send us all relevant information when you submit your complaint. If you need to send additional documents please email the information to and note that you filed a complaint and are providing additional documentation. Please be aware that Consumer Service 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 us any medical records.


What happens after you submit your complaint?

All complaints are reviewed upon receipt to ensure that they are within the jurisdiction of the DOI. If jurisdiction is identified, within two weeks of filing, 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) receives 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. Due to the volume of complaints received by CSU, complaints are handled in the order that they are received.

If your complaint is not within the Division of Insurance’s jurisdiction, we will help you identify the appropriate agency to review your concerns.

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.

If your complaint concerns a medical necessity denial, you should file a complaint with the Office of Patient Protection.
