Grievance | Medicare GlossaryMedicare Glossary Topic.
A complaint or dispute in regards to the way that your Medicare health or drug plan is operating or providing care. If you have a complaint, you may file a grievance within 60 days after the incident occurred. You can file a grievance for a problem such as difficulty calling the plan, the conditions of a facility, or if you are unhappy with the way a plan staff member has treated you. However, if you have a complaint about the plan's decision to refuse to cover a service, product or prescription, you must file an appeal.
