Medicare Appeal vs. Grievance: Which One Do You File?
An appeal challenges a coverage or payment decision. A grievance reports a service, conduct, quality or administrative problem. Sometimes the same event calls for both.
Ask what result you need
If you want Medicare or a plan to cover a service, pay a claim, change your cost-sharing or continue care, use the applicable appeal. If you want the plan or provider to address customer service, behavior, delay, facility conditions or quality, use a grievance or complaint. Filing a grievance does not protect an appeal deadline.
Appeal and grievance comparison
| Your problem | Usually use | Why |
|---|---|---|
| A service, medical item or drug was denied | Appeal | You are asking for the coverage decision to be changed |
| A claim was not paid or your cost is wrong | Appeal | The dispute concerns payment or cost-sharing |
| Hospital, skilled nursing, home health, hospice or CORF care is ending too soon | Fast appeal | A special expedited review may apply before coverage ends |
| Customer service was rude or repeatedly unhelpful | Grievance | The complaint is about conduct or service, not the coverage decision |
| You waited too long for an appointment or a plan response | Grievance; possibly appeal too | Complain about the delay and appeal if it also caused an unfavorable coverage result |
| You are concerned about quality of care | Complaint or grievance | The appropriate reviewer may be the plan, BFCC-QIO, State Survey Agency or another regulator |
What a Medicare appeal is designed to do
An appeal asks the decision-maker to reconsider a specific adverse determination. The exact route depends on whether the issue involves Original Medicare, Medicare Advantage, Part D or a fast appeal when covered care is ending.
Original Medicare
Use the instructions on the Medicare Summary Notice to challenge a Part A or Part B claim decision. The first level is a redetermination.
Medicare Advantage
Use the plan’s denial notice to request reconsideration. A denial involving prior authorization is still a coverage appeal, even if poor service also occurred.
Medicare Part D
Request a coverage determination first when a formal drug-coverage decision is needed, then use redetermination if the plan denies it.
Care ending
Follow the expedited instructions on the hospital or service-ending notice. These deadlines can arrive much sooner than an ordinary appeal deadline.
For detailed routes, visit the Medicare claims, denials and appeals hub, the guide to Medicare Advantage prior-authorization denials or the guide to Part D drug denials and exceptions.
What a Medicare grievance or complaint addresses
A grievance tells a Medicare health or drug plan about dissatisfaction with its operations, employees, contractors or service. Medicare also uses the broader word “complaint” for issues involving providers, facilities and quality of care. The correct destination depends on the problem.
- Customer service, staff behavior or difficulty getting information
- Unreasonable wait times or failure to respect your rights
- Problems with a plan’s notices, forms or administrative process
- Quality-of-care concerns
- Conditions at a hospital, nursing home, home health agency or other facility
Start by documenting dates, names, what happened and the resolution you are requesting. A plan’s Evidence of Coverage explains its grievance process. Quality or safety concerns may also be directed to a Beneficiary and Family Centered Care–Quality Improvement Organization, State Survey Agency or another oversight organization identified by Medicare.
When you may need both an appeal and a grievance
One event can create two different problems. Suppose a Medicare Advantage plan misses a required response and then denies a service. The appeal asks the plan to reverse the denial; the grievance reports the delay or process failure.
- Protect the appeal first. Read the denial or termination notice and calendar its filing deadline.
- State the coverage result you want. Identify the service, drug, payment or continuation of care being requested.
- File the grievance separately. Describe the delay, conduct, communication or quality problem and what should be corrected.
- Keep two records. Save confirmation numbers, copies, fax receipts and names for each process.
- Follow both tracks. A response to one filing does not necessarily resolve the other.
Do not substitute a grievance for an appeal
Calling something a “complaint” may not start the coverage-appeal process. Use the terminology and submission instructions printed on the plan, claim or care-ending notice.
What to include with either filing
For an appeal
- The decision or denial notice
- Member and claim information
- The disputed service, drug or amount
- Clinical records or prescriber support
- A direct response to the denial reason
For a grievance
- Dates, locations and people involved
- A concise description of the problem
- Copies of messages or prior contacts
- How the problem affected you
- The corrective action requested
Keep originals whenever possible. Submit copies through a trackable channel, and record when the plan or agency confirms receipt.
Appeal and grievance FAQs
What is the simplest difference between a Medicare appeal and grievance?
An appeal challenges a coverage, payment, cost-sharing or care-ending decision. A grievance complains about service, conduct, administration or quality.
Can I file an appeal and grievance about the same event?
Yes. Use the appeal to seek a different coverage result and the grievance to report a separate service, delay, communication or quality problem.
Does filing a grievance extend my appeal deadline?
No. Treat the appeal deadline on the notice as controlling and file the grievance separately.
Is a complaint about a denied prior authorization an appeal?
The request to reverse the denial is an appeal. If the plan also caused an administrative or service problem, a separate grievance may be appropriate.
Is poor quality of care an appeal or grievance?
It is generally a complaint or grievance rather than a coverage appeal. Medicare may direct quality concerns to the plan, BFCC-QIO, State Survey Agency or another appropriate reviewer.
Where do I find the filing instructions?
Use the denial, claim or care-ending notice for an appeal. For a grievance, check the plan’s Evidence of Coverage or Medicare’s complaint guidance.
What if I am not sure which process applies?
Ask the plan or Medicare whether the issue affects coverage or payment, service or quality, or both. Do not wait to clarify if an appeal deadline is near.
Can a Medicare broker decide an appeal or grievance?
No. A broker may help identify the appropriate contact or plan document, but the plan, Medicare contractor or designated review organization decides the matter.
