Medical-payments coverage is typically $1,000 to $10,000 for each person protected by your policy. It would cost you relatively little to raise the coverage to a higher amount.

One policy may pay medical expenses only for the first year after an accident, another for the first three years afterward, and still another up to five years, provided you buy more than a stipulated amount of protection. Payments may be reduced by any amount that you receive or are entitled to receive from other parts of the policy or from other sources.
