Grievances

What is a Grievance?

A grievance is a complaint about anything other than benefits, coverage or payment. You would file a grievance if you had problems with the value of your medical care, waiting times or the customer service you receive. You would file a grievance if you did not think we responded fast enough to your request for coverage determination or organization determination, or to your appeal.
