A complaint about the way a Medicare health plan is giving care. For example, insureds may file a grievance if they have problems with the health care facility (such as cleanliness), staff behavior, or operating hours. Likewise, insureds many file a grievance if they have problems calling the plan. Note that a grievance is not the same as an appeal, which is the way to deal with a complaint about a treatment decision or a service that is not covered (see the definition of appeal).
