Member Satisfaction

Trillium Community Health Plan wants to give the best care and services to our members.  

You have a right to make a complaint if you are not satisfied with any part of your care. We will try to make things better. 

  • A complaint is letting us know you are not satisfied.  
  • A dispute is when you do not agree with Trillium Community Health Plan or a provider.  
  • A grievance is a complaint you can make if you are not happy with Trillium Community Health Plan, your healthcare services, or your provider. A dispute can also be a grievance. To make it easy, OHP uses the word complaint for grievances and disputes, too.
