1. Why Insurers Deny Valid Claims 📉
| Common Denial Trigger | 2024-25 Data Point | Why It Matters |
|---|---|---|
| “Missing” documentation or miscoding | Up to 17 % of marketplace claims are denied, often for paperwork quirks | Insurers count on paperwork inertia (KFF) |
| Prior-authorization red tape | MA insurers denied 7.4 % of PA requests in 2022 | Burdens patients before care is even delivered (Investopedia) |
| Few consumers fight back | Only 0.2 % of denials were appealed in 2021 | Low appeal volume emboldens payers (KFF) |
