What is a Grievance?

A Grievance is a complaint for any service other than an organization determination. A complaint is telling us that you are not happy with a Medicare health plan or contracted provider offered health care services, even if nothing can be done right away. An enrollee or their appointed representative may make the complaint, either orally or in writing, to a Medicare health plan, provider, or facility. An expedited grievance may also include a complaint that a Medicare health plan did not allow to expedite an organization determination or reconsideration, or called upon to allow more time to file a complaint for an organization determination or reconsideration.

It is a way of telling us that you are not happy about wait times at the doctor’s office, how long it took for you to get an appointment, cleanliness of the doctor’s office, behavior by doctor’s office staff, or the quality of care you got by a doctor.

You can tell us that you are not happy about our decision when you asked for certain services and our payment. If you are not happy with anything about us or our providers you may file a complaint/grievance. You need to file your complaint/grievance within 60 days of when it happened. If you have a good reason for being late in turning in a complaint/grievance, let us know and we will choose whether or not to give you more time for turning in a complaint/grievance.
