Which document is typically used to verify expenses and dates of service when filing a claim?

• A. Policy declaration page
• B. Explanation of benefits
• C. ID card
• D. Proof of loss

Answer: (D)

The document used to verify expenses and dates of service when filing a claim is proof of loss. This sworn statement provides the insurer with the factual details of the claim—what services were provided, when they occurred, and how much was charged—so benefits can be determined accurately. The policy declaration page shows the contract terms and coverage, but doesn’t verify specific claims. An explanation of benefits is produced after the claim is reviewed to explain payments, not to substantiate the claim itself. An ID card helps identify the insured and plan details, not the actual services or costs. So proof of loss directly serves as the verification of expenses and service dates.
