The six sectionsevery denial letter contains.
Most insurer denial and underpayment letters follow a similar structure. Knowing where to look helps you find the information that matters most.
Claim & Loss Information
Claim number, date of loss, first notice of loss (FNOL), and policy number. Deadlines for proof of loss and supplemental claims typically run from these dates.
Coverage Determination
The core of the letter — which parts of your claim are covered, denied, or partially paid, and the stated reason for each.
Cited Exclusions & Clauses
The specific policy language the insurer relies on — wear and tear, flood exclusion, anti-concurrent causation. Ask for the exact section and page if it isn't quoted directly.
Valuation & Payment Calculation
How the paid amount was calculated — ACV vs. RCV, depreciation applied, and which deductible (standard or hurricane/wind) was subtracted.
Reservation of Rights
Language preserving the insurer's ability to investigate further or deny later, even if a payment has been issued. Not the same as a final approval.
Next Steps & Deadlines
Instructions for proof of loss, supplemental claims, appraisal, or appeal — along with any state-specific statutory deadlines mentioned.
Common term categoriesyou will find in your letter.
Denial and underpayment letters draw from a few recurring vocabularies. Here are the four most common, with examples.

The stated grounds insurers cite for denying all or part of a claim.
| Term | Meaning |

| WEAR AND TEAR | Gradual deterioration, not sudden damage |
| ANTI-CONCURRENT CAUSATION | Excluded + covered cause combined |
| LATE NOTICE | Reported after the required window |
How Your Payout Was Calculated
The math behind the dollar amount in your letter.
| Term | Meaning |
|---|---|
| ACV | Replacement cost minus depreciation |
| RCV | Replacement cost, no depreciation deducted |
| HURRICANE DEDUCTIBLE | Percentage-based storm-specific deductible |
Procedural & Investigation Terms
Steps and requirements in the claim lifecycle, from first notice to appraisal.
| Term | Meaning |
|---|---|
| PROOF OF LOSS | Sworn itemized damage statement |
| EUO | Examination Under Oath |
| APPRAISAL CLAUSE | Neutral panel resolves a dollar dispute |
When Handling Itself Becomes the Issue
