If you have issues with Medicare or Medicaid care in 2026, there are ways to raise your concerns. For quick questions or serious complaints, you can start with Patient Advocate Liaison Services (PALS) for informal help, or use formal complaint channels if needed. Here’s a step-by-step guide to help you understand what to do and where to file your complaint.

Quick Summary: Medicare and Medicaid Complaint Options

  • PALS: The first point of contact for informal help and guidance, available through your Medicare Advantage plan or Medicaid managed care organization.
  • Formal Complaints: For serious issues such as fraud, abuse, denial of medically necessary services, or plan violations. These complaints are handled by federal or state agencies depending on your coverage.
  • Costs: Filing complaints is completely free. There are no fees or charges for submitting either informal or formal grievances.
  • Deadlines: It’s best to file complaints as soon as possible. Medicare advises submitting formal complaints within 60 days of the incident or denial, while Medicaid deadlines vary by state but generally range from 30 to 90 days.
  • Where to File: Use Medicare.gov for Medicare complaints or your state Medicaid agency’s website for Medicaid issues. Contact information is also available through your plan materials.

What You Need Before You Start

Before you complain about Medicare or Medicaid care, make sure to gather all relevant information. This includes your Medicare or Medicaid ID number, which is usually on your insurance card. Also collect the dates when the services were provided, the names and contact details of the healthcare providers involved, and any related bills, explanation of benefits (EOB) statements, or correspondence you’ve received.

Having these documents ready speeds up processing and ensures your complaint is clear and complete. If you’re complaining about denied services, include any letters or notices explaining the denial.

You also need to identify whether your issue is with Medicare, which is federally managed, or Medicaid, which is run by your state. Medicare complaints typically go through federal channels, while Medicaid complaints are handled by your state’s Medicaid office. Knowing this helps you file in the right place.

Step 1: Contact Patient Advocate or Liaison Services (PALS)

PALS is your first stop for informal help. Patient Advocate Liaison Services exist within many Medicare Advantage plans and Medicaid managed care organizations (MCOs) to support beneficiaries.

They help explain your benefits, answer questions, and try to resolve problems without formal proceedings.

To reach PALS:

  1. Call the customer service number on your Medicare Advantage or Medicaid MCO insurance card.
  2. Ask to speak with a Patient Advocate or Patient Liaison.
  3. Clearly explain your issue, whether it’s a billing error, confusion about coverage, or denied service. Provide any documentation you have on hand.
  4. Request an explanation of what they will do to address your concern and ask for an estimated timeline for resolution.

PALS representatives often help fix billing errors, explain coverage details, or assist with scheduling appointments. They don’t have the authority to enforce rules or issue penalties, but they often resolve problems quickly by coordinating between you and your provider or plan.

Keep a record of your PALS interactions, including the date, name of the advocate, and what was discussed. This will help if you need to escalate your complaint later.

Step 2: File a Formal Complaint with Medicare

If PALS can’t fix your problem, or if your complaint involves serious issues like fraud, abuse, or denial of medically necessary care, you should file a formal complaint with Medicare.

Formal complaints require more detailed information and are investigated by Medicare’s complaint and appeals departments. These complaints are taken seriously and can trigger audits or investigations into providers or plans.

Here’s how to file a Medicare complaint in 2026:

  1. Go to Medicare.gov's Complaints and Appeals page.
  2. Select the type of complaint you want to file, such as Medicare Advantage, Part D prescription drug plan, or Original Medicare.
  3. Fill out the online complaint form with your personal details, Medicare ID, and a detailed description of your issue. Attach any relevant documents like letters, bills, or notices.
  4. Submit the form. You’ll receive a confirmation number and instructions on what to expect next.

You can also file complaints by phone at 1-800-MEDICARE (1-800-633-4227) or by mailing a written complaint to the address listed on Medicare.gov. Keep copies of all correspondence.

Medicare usually resolves formal complaints within 30 to 90 days, depending on how complex the issue is. You’ll be notified of the outcome by mail or email.

Step 3: File a Formal Complaint with Medicaid

Medicaid complaints vary by state but generally follow a similar process. Since Medicaid is state-run, you’ll file complaints through your state’s Medicaid agency or Medicaid managed care plan if you have one.

To file a Medicaid complaint:

  1. Find your state Medicaid agency’s contact info at Medicaid.gov’s state contacts page.
  2. Contact your Medicaid managed care organization’s customer service line and ask to speak with a Patient Advocate or file a grievance.
  3. If the issue isn't resolved informally, request instructions for filing a formal complaint or grievance with the state agency.
  4. Submit your complaint online, by phone, or in writing as directed. Include your Medicaid ID number, details of the problem, dates, provider names, and any supporting documents.

Medicaid agencies typically respond within 30 to 90 days.

Some states offer ombudsman programs to help beneficiaries with complaints and appeals.

Tips for a Successful Complaint

  • Be clear and specific: Describe your problem in plain language with dates and names.
  • Keep records: Save copies of bills, letters, and notes from phone calls with dates and names.
  • Follow up: If you don’t hear back in the expected time, contact the agency to check on your complaint status.
  • Use official channels: File complaints only through Medicare.gov or your state Medicaid agency to ensure they’re processed.
  • Meet deadlines: File complaints promptly. Medicare recommends within 60 days; Medicaid varies but often 30-90 days.

Common Mistakes to Avoid

  • Not gathering all documents: Missing info slows down complaint processing.
  • Failing to identify the right agency: Medicare and Medicaid have different complaint processes.
  • Skipping PALS: Trying to file formal complaints without first seeking informal help can slow resolution.
  • Ignoring deadlines: Late complaints may not be accepted or investigated.
  • Being vague: Complaints lacking detail or evidence often get delayed or dismissed.

Complaining about Medicare or Medicaid care in 2026 is straightforward if you know the steps. Start with PALS for quick help resolving routine issues. If that doesn’t work or your problem is more serious, file a formal complaint online through Medicare.gov or your state Medicaid agency. Keep your records organized and act promptly to protect your rights.
