Grievance
Quick answer
A grievance is a formal complaint to your plan about service quality, access, or the appeals process — not about coverage decisions themselves.
Plain-English definition
Grievances usually must be filed within 60 days of the event.
Why it matters
Grievances create a paper trail and can drive service improvements.
A simple example
You file a grievance after long wait times at the plan's customer service line.
