You Just Got Denied β Here's What to Do Right Now
Getting a Medicaid denial for your continuous glucose monitor (CGM) or diabetes supplies is devastating β especially when you depend on that device to manage your health safely. You're not alone, and more importantly, you are not out of options. Medicaid denials are overturned every day by patients who know how to fight back. This guide gives you the exact steps, language, and deadlines to appeal your denial effectively.
Step 1: Read Your Denial Letter Carefully
Your denial letter is your roadmap. Look for these specific terms:
- "Not medically necessary" β the most common reason; requires a clinical appeal with physician documentation
- "Non-covered benefit" β requires a formulary exception or coverage determination request
- "Prior authorization not obtained" β your doctor may need to resubmit the PA with additional clinical criteria
- "Step therapy required" β insurer claims you must try a different device first
Write down your denial reason, your claim number, and the appeals deadline. Most Medicaid plans allow 60β90 days to file an internal appeal, but some states allow as few as 30 days. Do not wait.
Step 2: Request Your State's Medicaid Appeal Form Immediately
Every state Medicaid program has an internal grievance and appeals process. Call your Medicaid managed care plan (the number on your card) and say exactly this:
"I am calling to file a formal appeal of a coverage denial for a continuous glucose monitor. My claim number is [NUMBER]. I am requesting the appeal form and the name of the appeals department mailing address. I also want to know the deadline to file and whether I can request an expedited appeal due to medical urgency."
If your doctor agrees that waiting for a standard appeal puts your health at risk, request an expedited appeal. Medicaid plans must respond to expedited appeals within 72 hours under federal CMS regulations (42 CFR Β§ 438.408).
Step 3: Build Your Clinical Case β Get These Documents
A strong appeal includes more than a complaint. Gather the following before you file:
- A Letter of Medical Necessity from your endocrinologist or primary care physician detailing your diagnosis (Type 1 or Type 2 diabetes), frequency of hypoglycemic episodes, and why a CGM is clinically necessary
- Recent A1C lab results and blood glucose logs showing instability
- Documentation of hypoglycemia unawareness if applicable β this is one of the strongest clinical justifications
- Published clinical guidelines from the American Diabetes Association (ADA) supporting CGM use β cite the ADA Standards of Medical Care in Diabetes, which recommend CGM for anyone using insulin
- Your state's Medicaid CGM coverage policy, which you can request from your plan or find on your state Medicaid agency website
Step 4: Write Your Internal Appeal Letter
Use this sample letter as your template:
[Your Name]
[Address]
[Date]
Re: Formal Appeal of CGM Coverage Denial β Claim #[NUMBER]
Dear Medicaid Appeals Department,
I am writing to formally appeal the denial of coverage for a continuous glucose monitor (CGM) system, denied on [DATE]. The denial cites [DENIAL REASON]. I believe this denial is incorrect and not supported by clinical evidence or Medicaid coverage guidelines.
I am a [Type 1/Type 2] diabetic currently managing my condition with insulin. My physician, Dr. [NAME], has determined that a CGM is medically necessary to prevent life-threatening hypoglycemic episodes. My most recent A1C is [VALUE], and I have experienced [NUMBER] documented hypoglycemic events in the past [TIMEFRAME].
Per the American Diabetes Association's Standards of Medical Care in Diabetes (2024), CGM is a recommended standard of care for insulin-using patients. I am requesting that this denial be overturned and CGM coverage be approved immediately. Attached please find: (1) Letter of Medical Necessity from Dr. [NAME], (2) recent lab results, (3) ADA clinical guidelines.
Sincerely,
[Your Name]
[Phone Number]
[Medicaid ID Number]
Step 5: If Internal Appeal Fails β Go External
If your Medicaid plan denies your internal appeal, you have the right to an external appeal reviewed by an independent organization. Under federal Medicaid law, you can also request a State Fair Hearing β an administrative court proceeding where a neutral judge reviews your case. Request this in writing immediately after an internal denial.
Additionally, file a complaint with your State Insurance Commissioner (even for Medicaid managed care plans) and contact your state's Medicaid ombudsman, a free patient advocate required by federal law in every state. Find yours at medicaid.gov.
Key Deadlines by State (Always Verify)
- California (Medi-Cal): 90 days to appeal; 3 days for expedited
- Texas (STAR): 120 days to appeal; 72 hours expedited
- Florida: 90 days; State Fair Hearing available
- New York: 60 days internal; Fair Hearing within 90 days of denial
- All other states: Call your plan immediately β assume 30 days minimum
