You're Not Alone
Getting denied doesn't mean the answer is no forever. It means the insurer needs more information — or you need to push back. You have the right to appeal, and complete documentation that addresses the specific denial reason puts your appeal on stronger footing.

Full appeals guide →What Insurers Look For in Approvals
- BMI documentation — Recent measurements (ideally <6 months)
- Comorbidity codes — Type 2 diabetes, hypertension, sleep apnea, etc.
- Prior medication history — What you've tried before and why it failed
- Lifestyle modification proof — Diet/exercise programs, dietitian visits
- Physician letter of medical necessity — Explaining why Foundayo specifically
Missing any of these is a common reason for denial. Your appeal should address the gap.

What to Do Right Now
Find Your Denial Letter
Look for the specific reason they denied you. It's usually in a paragraph that starts with "Your request was denied because..." This determines your appeal strategy.
Note Your Deadline
You have 180 days from the denial date to file an internal appeal (under most plans). Missing this deadline typically forfeits your right to appeal. Mark it on your calendar.

Honest Care writes your personalized appeal letter for free. We'll ask a few questions about your situation and denial, then create an insurer-ready letter.

Appeals Actually Work
Many insurers expect patients not to appeal — which is why taking action matters. The appeal process exists for a reason, and it often works.

Common questions after a denial
Quick Answers
Yes. You have several options: (1) Appeal the denial — 65%+ of appeals succeed with proper documentation. (2) Pay cash — LillyDirect offers Foundayo at $149–$299/month (see current pricing). (3) Use the savings card — If your appeal succeeds and you have commercial insurance coverage, pay as low as $25/month with the manufacturer savings card. Without coverage, the savings card reduces cost to LillyDirect self-pay levels ($149–$299/month), not $25. The savings card excludes Medicare, Medicaid, and government programs.
You typically have 180 days from the date on your denial letter to file an internal appeal (check your plan documents for exact deadlines). After that, you may lose your right to appeal. Mark your calendar and don't wait.
Good. 65%+ of appeals succeed when you have proper documentation (AMA/KFF data). The key is addressing the specific reason you were denied and providing the right evidence.
Yes. LillyDirect offers Foundayo at reduced cash prices without insurance (see current pricing). This lets you start treatment while your appeal is pending. If your appeal succeeds, some plans may reimburse part of your out-of-pocket costs.
WHAT'S CHANGING
Foundayo Denials: 2026 Outlook
2026: Mixed Outlook for Coverage
While more employers are adding GLP-1 coverage (estimated 25%+ in 2026, up from 19%), denial rates remain high due to stricter PA requirements and cost management strategies.
CMS Prior Authorization Reform
The CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F) takes effect in 2026:
- Faster 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 (so it doesn't change Foundayo prior authorization timelines)
- Transparency: Insurers must disclose denial reasons clearly
- Digital integration: PA requests through electronic health records
If Appeals Fail: Cash Pay Option
For patients who exhaust appeal options, LillyDirect offers Foundayo at reduced cash prices — significantly lower than standard retail.
