How to Appeal a Medicare Coverage or Billing Decision in Las Vegas, Henderson, and Clark County
If you’re a Medicare beneficiary in Las Vegas, Henderson, or anywhere in Clark County, you may have encountered a situation where Medicare denied coverage for a medical service, treatment, or prescription drug you believed was necessary. If this happens, you have the right to appeal the decision. Understanding the appeal process can help you fight for the coverage you need.
What Is a Medicare Appeal?
A Medicare appeal is a formal request asking Medicare to review and reconsider a decision they made about your coverage or costs. You can file an appeal if Medicare denies:
- A medical service, procedure, or test you believe should be covered.
- A prescription drug you need.
- Payment for a service or item you already received.
- A request to change the amount you have to pay.
Steps to Appeal a Medicare Decision
Step 1: Review Your Medicare Summary Notice (MSN) or Explanation of Benefits (EOB)
If you are in Original Medicare (Part A and Part B), you’ll receive a Medicare Summary Notice (MSN) that details services and items Medicare covered and denied. If you have a Medicare Advantage (Part C) or a Prescription Drug Plan (Part D), you will receive an Explanation of Benefits (EOB) from your plan provider.
Step 2: Determine the Appeal Deadline
Time is critical when filing an appeal. The deadline depends on the type of Medicare coverage you have:
- Original Medicare (Parts A & B): You must file an appeal within 120 days of receiving your MSN.
- Medicare Advantage (Part C): You must appeal within 60 days of receiving your denial notice.
- Medicare Prescription Drug Plan (Part D): You must appeal within 60 days of receiving the denial.
Step 3: Gather Supporting Documents
To strengthen your appeal, collect relevant medical records, doctor’s notes, prescriptions, and any letters from healthcare providers explaining why the service or medication is necessary. If you are in Las Vegas, many local healthcare providers, such as UMC, Sunrise Hospital, or Intermountain Healthcare, can provide documentation to support your case.
Step 4: File Your Appeal
The process for submitting your appeal depends on your Medicare plan type:
- Original Medicare: Fill out the Redetermination Request Form (available at Medicare.gov) and mail it to the address provided on your MSN.
- Medicare Advantage: Contact your Medicare Advantage plan provider directly. You may need to submit a written appeal or call their appeals department.
- Medicare Part D: File an appeal with your Part D plan provider by submitting a written request or calling their customer service.
For urgent situations, such as needing a prescription drug immediately, you can request an expedited appeal, which must be reviewed within 72 hours.
Step 5: Follow Through with the Appeals Process
Medicare appeals can go through multiple levels. If your first appeal is denied, you can escalate it to the next level:
- Redetermination (First Level) – The initial review by Medicare or your plan provider.
- Reconsideration (Second Level) – A different, independent entity reviews your appeal.
- Administrative Law Judge (ALJ) Hearing (Third Level) – If the appeal is still denied and the amount in dispute is over $180 (2025 threshold), you can request a hearing with an ALJ.
- Medicare Appeals Council (Fourth Level) – A final review within Medicare.
- Federal Court Review (Fifth Level) – If all previous levels fail, you can take the case to a federal court.

Real-World Example
Let’s say Mary, a Medicare beneficiary in Henderson, visits her specialist at St. Rose Dominican Hospital for a medically necessary treatment. She later receives an MSN stating that Medicare denied coverage for the procedure, leaving her with a large bill. Mary contacts her doctor, who provides a letter explaining why the treatment was essential. She files a redetermination request along with the doctor’s statement and supporting medical records. A few weeks later, Medicare reverses its decision, and the claim is approved.

If Medicare denies a service or treatment, don’t assume it’s the final decision.
