UNDERSTANDING YOUR OPTIONS
What Is External Review?
A Fresh Set of Eyes
External review means your case is evaluated by independent medical experts—not your insurance company. Under the Affordable Care Act, you have the legal right to request this review after your internal appeal is denied.[1]
When your insurer denies your Foundayo coverage and upholds that decision on internal appeal, you're not out of options. External review takes your case outside the insurance company entirely.

Internal Appeal vs. External Review
| Feature | Internal Appeal | External Review |
|---|---|---|
| Who Reviews | Insurance company employees | Independent Review Organization (IRO) |
| Timeline | 30 days for services not yet received; 60 days for services already received (faster if urgent) | 45 days (72 hrs expedited) |
| Success Rate | ~44% | 40-60%+* |
| Binding? | No—insurer can deny again | Yes—insurer must comply |
| Cost | Free | Free (federal) or max $25 (state) |
*Rates vary significantly by state, case type, and documentation quality. The 40-60% range reflects medical necessity cases with strong documentation; general overturn rates across all case types are lower (~27%).
The key difference: external review decisions are binding. If the independent reviewer rules in your favor, your insurance company is legally required to cover your medication.[1]
For information on internal appeals, see our Foundayo appeals overview or specific guides for medical necessity denials.
EXTERNAL REVIEW REQUIREMENTS
When Are You Eligible?
Under the ACA (Affordable Care Act), you can request external review when:[2]
Your internal appeal was denied
After your insurance company issues their final denial letter (officially called a "final adverse benefit determination"), you have 4 months to request external review (some states allow longer).
Your case is urgent (expedited)
For urgent health situations, you can file for external review at the same time as your internal appeal. Qualifying situations include:
- Your health condition could seriously deteriorate without treatment
- Waiting would jeopardize your ability to regain maximum function
- You're experiencing severe pain that requires immediate treatment
Expedited reviews are decided within 72 hours or less.
The denial involves medical judgment
External review is available when your insurer denies coverage based on:
- Medical necessity — "Foundayo isn't medically necessary for your condition"
- Experimental/investigational — "This treatment is considered experimental"
- Clinical judgment — Any decision where medical opinion is involved
Note: Denials based purely on contractual exclusions (like "weight loss medications excluded from benefits") may not qualify for external review.
Your coverage was cancelled
If your insurer cancels your coverage based on claims that you gave false or incomplete information when you applied, you have the right to external review of that decision.
Don't Miss Your Deadline
You have 4 months from the date of your final internal denial to request external review. This deadline is strict—if you miss it, you may lose your right to independent review.[1]
STEP-BY-STEP PROCESS
How to Request External Review
Follow these steps to file for external review of your Foundayo denial:
Get Your Final Denial Letter
Request your final denial letter in writing from your insurer (they may call it a "final adverse benefit determination"). This letter should include:
- The specific reason for denial
- Information about your external review rights
- Instructions on how to request external review
- The deadline to file (usually 4 months from this letter)
Determine Your Review Process
Your external review process depends on your plan type and state:
- State process: Most states have their own external review programs (CA, NY, etc.)
- Federal process: Some states use the federal process administered by the U.S. Department of Health and Human Services (HHS) through MAXIMUS (TX, FL, GA, PA, WI, AL)
Check your denial letter or call your state insurance department to confirm which process applies to you.
Gather Your Documentation
Collect everything that supports your case:
- Final denial letter from your insurer
- All correspondence from your internal appeal
- Medical records documenting your condition
- Letter of Medical Necessity from your doctor
- Clinical evidence (ATTAIN trial data, guidelines)
- Documentation of prior weight loss attempts
File Your External Review Request
Federal process (MAXIMUS):
- Online portal: externalappeal.cms.gov
- Phone: 1-888-866-6205
- Mail: MAXIMUS Federal Services, 3750 Monroe Avenue, Suite 705, Pittsford, NY 14534
State process: Contact your state insurance department for specific filing instructions.
Consider Provider Assistance
You can appoint a representative (like your doctor) to file on your behalf. Many providers will:
- Submit the external review request for you
- Write a letter of support with clinical justification
- Provide additional medical documentation
Wait for the Decision
Within 5 business days, you'll receive confirmation that your request was received. Then:
- Standard review: Decision within 45 days

STRENGTHENING YOUR CASE
What Reviewers Look For
Independent reviewers are medical professionals who evaluate your case based on clinical evidence and medical standards—not cost considerations. Here's what makes a strong external review case for Foundayo:
Documentation Checklist
What to Include in Your External Review
- Final denial letter from your insurer
- All internal appeal correspondence
- Medical records showing obesity diagnosis (BMI—body mass index—of 30 or higher, or 27+ with weight-related health conditions)
- Documentation of related health conditions with diagnosis codes (type 2 diabetes, high blood pressure, sleep apnea, etc.)
- Prior treatment history (diet programs, exercise, other medications tried)
- Letter of Medical Necessity from your prescribing physician
- Clinical evidence (ATTAIN trials, FDA approval, professional guidelines)
Clinical Evidence That Supports Foundayo
Include these key data points in your external review submission:
| Evidence Source | Key Finding | Why It Matters |
|---|---|---|
| ATTAIN-1 Trial[8] | ~12% weight loss at 72 weeks | Far exceeds 3-5% from lifestyle alone |
| ATTAIN-2 Trial[9] | 9.6% weight loss in patients with type 2 diabetes | Demonstrates effectiveness for obesity with diabetes |
| FDA Approval (April 2026)[10] | Approved for chronic weight management | Not experimental or investigational |
| AMA Recognition (2013)[11] | Obesity classified as disease | Treatment is medical, not cosmetic |
How to Present Your Case
Sample Language for External Review
Opening:
"I am requesting external review of [Insurance Company]'s denial of coverage for Foundayo (orforglipron). My internal appeal was denied on [date], and I believe this decision does not reflect current medical standards or the clinical evidence supporting this medication's necessity for my condition."
Medical necessity argument:
"Obesity is recognized as a chronic, relapsing disease by the American Medical Association (2013), World Health Organization, and CDC. My documented BMI of [X] kg/m² and related health conditions including [list conditions] meet the FDA-approved criteria for Foundayo treatment. Clinical trials (ATTAIN-1) demonstrate ~12% weight loss with orforglipron, significantly exceeding the 3-5% typically achieved through lifestyle modification alone."
Prior treatment failure:
"I have attempted multiple weight management approaches including [diet programs, exercise regimens, other medications], as documented in my medical records. These interventions did not produce sustained weight loss, demonstrating the medical necessity of pharmacological treatment."
Pro tip: Reference the exact language from your insurer's denial and directly counter each point with clinical evidence.

Success Rate Statistics
External Reviews Have Higher Success Rates
External review success rates range from 40-60% depending on the case type and jurisdiction. In California, the Department of Managed Health Care reports that 60-80% of denials taken to Independent Medical Review are reversed.[3]
Key statistics from published research:
WHICH APPLIES TO YOU
State vs Federal Programs
Your external review process depends on your state and plan type. Most states have their own external review programs, but some use the federal HHS process.[7]
State vs. Federal External Review
State programs apply if your state has an external review process that meets or exceeds ACA standards. Many state programs offer stronger consumer protections.
Federal program (MAXIMUS) applies in states without compliant programs: Alabama, Florida, Georgia, Pennsylvania, Texas, and Wisconsin—plus self-funded employer plans in any state.
State External Review Examples
| State | Program | Key Features |
|---|---|---|
| California | Department of Managed Health Care (DMHC) Independent Medical Review | 60-80% overturn rate; specialist reviewers required; SB 1120 prohibits AI-only denials |
| New York | DFS External Appeal | Strong protections; automatic external review available; specialist reviewer required |
| Texas | Federal (MAXIMUS) | Uses HHS process; 72-hour expedited option; free to patients |
| Florida | Federal (MAXIMUS) | Uses HHS process; ACA minimum protections apply |
How to find your state's process:
- Check your final denial letter—it should include external review instructions
- Visit your state insurance department website
- Call your state insurance commissioner's office
- Or use the KFF state external review lookup
EXTERNAL REVIEW FOR FOUNDAYO
Frequently Asked Questions
External review is an independent evaluation of your insurance denial by medical professionals who don't work for your insurer. Under the Affordable Care Act (ACA), you have the legal right to request external review after your internal appeal is denied. An Independent Review Organization (IRO) examines your case based on clinical evidence and medical standards, and their decision is binding on your insurance company.
You can request external review after your insurance company issues a final internal denial. You have 4 months from the date of that final denial to file. For urgent health situations, you can request expedited external review at the same time as your internal appeal.
External review success rates vary but are generally higher than internal appeals. Studies show rates of 40-60% for cases that reach external review. In California, the Department of Managed Health Care reports that 60-80% of denials taken to Independent Medical Review are reversed. However, less than 1% of denied claims are ever appealed, despite these relatively high success rates.
Standard external reviews must be decided within 45 days of filing. For urgent or expedited cases, decisions must come within 72 hours or less. You'll receive confirmation that your request was received within 5 business days.
The HHS-administered federal external review process is free. State external review programs may charge a fee, but it cannot exceed $25 per external review request.
Most states have their own external review programs that meet or exceed ACA standards. Some states (Alabama, Florida, Georgia, Pennsylvania, Texas, Wisconsin) use the federal HHS process administered by MAXIMUS. Self-funded employer plans typically use the federal process regardless of state. Your denial letter should indicate which process applies to you.
Yes. Under the ACA, external review decisions are binding on your insurance company. If the independent reviewer rules in your favor, your insurer is legally required to cover the medication or service.
Yes. You can appoint a representative, such as your doctor or another healthcare provider, to file the external review on your behalf. Many providers will also write letters of support and provide additional documentation to strengthen your case.
YOUR PATH FORWARD
What's Next
WHAT'S CHANGING
External Review: 2026 Outlook
2026: State External Review Reforms Expanding
Several states are strengthening their independent medical review processes. California's SB 1120 now prohibits AI-only denials, requiring physician oversight—a model other states are considering. These reforms may improve external review success rates as more cases receive thorough human evaluation.
CMS Prior Authorization Rule Impact
A new federal rule (CMS-0057-F) takes effect in 2026, requiring insurers to be more transparent about coverage decisions:
- Faster prior authorization decisions: From January 1, 2026, Medicare Advantage, Medicaid and CHIP must decide medical prior authorizations within 7 days (72 hours if urgent); the rule excludes drugs
- Denial reason disclosure: Insurers must explain specific reasons
- Better documentation: Clearer criteria may strengthen external review cases
These requirements apply to Medicare Advantage, Medicaid and CHIP medical-service decisions; because the rule excludes drugs, they don't apply to GLP-1 prescription denials.
If External Review Fails: TrumpRx Option
For patients who exhaust all appeal options, LillyDirect sells Foundayo at self-pay prices. TrumpRx.gov (launched February 5, 2026) lists these same LillyDirect prices and sends orders to LillyDirect:
- 0.8mg and 2.5mg: $149/month (2.5mg price is temporary through December 31, 2026)
- 5.5mg: $199/month (temporary through December 31, 2026)
- 9mg–17.2mg: $299/month ($349 for 14.5mg and 17.2mg if not refilled within 45 days)
This bypasses insurance entirely. Requires a prescription. Visit lillydirect.com for current pricing.
Medicare Coverage Options Expanding
Medicare and weight-loss GLP-1s: the Medicare GLP-1 Bridge
Through the Medicare GLP-1 Bridge (July 1, 2026 – December 31, 2027), a temporary CMS demonstration that runs outside the Part D benefit, people with eligible Part D coverage can get Wegovy, Foundayo or the Zepbound KwikPen for weight loss for $50 a month, if they meet CMS’s eligibility criteria and their prescriber gets prior authorization.
Source: CMS, Medicare GLP-1 Bridge · Facts in this box verified October 5, 2026
Note: Foundayo (orforglipron) is FDA-approved only for chronic weight management. For OSA coverage, Zepbound (tirzepatide) has a separate FDA-approved OSA indication.
If your external review failed, discuss alternative coverage pathways with your doctor, including the cost and savings options available for Foundayo.
