Within how many days must written proof of loss be submitted after a loss occurs?

The requirement for submitting written proof of loss after a loss occurs is typically set at a specific timeframe to ensure prompt processing of insurance claims. In this case, the correct answer is based on standard insurance practices, where written proof of loss must generally be submitted within 90 days after the loss. This timeframe allows both the insured party and the insurer to handle the claim efficiently and ensures that relevant documents and evidence are submitted while the details are still fresh and accessible.

By adhering to the 90-day requirement, it helps prevent delays in claim processing, ensures that necessary information is provided, and facilitates a smooth claims experience for all parties involved. The other timeframes listed (30 days, 60 days, and 120 days) do not align with standard practices for most health and accident insurance policies, making the 90-day period a common benchmark in the industry for proof of loss submissions.
