When submitting a claim, what must the insured provide to the insurer?

The requirement for the insured to provide proof of loss within a specified period is essential for processing a claim. This proof typically includes documentation that verifies the occurrence of an event that led to the claim, such as medical records, bills, or other relevant information that substantiates the loss being claimed. This requirement helps the insurer to assess the validity of the claim and determine the appropriate payout.

Timely submission of proof of loss is also crucial, as insurers often have specific deadlines within which a claim must be filed to be considered valid. By adhering to this requirement, the insured not only facilitates a smoother claims process but also ensures compliance with the terms of the insurance policy, which may stipulate these timeframes.

The other options, while potentially relevant in different contexts, do not represent the primary responsibility of the insured when initiating a claim. The summary of medical treatments, payment for the deductible, and a detailed medical history may all be components of the overall process but do not specifically fulfill the requirement of providing proof of loss.
