Insurance: other; post-claim underwriting; prohibit. Amends sec. 2026 of 1956 PA 218 (MCL 500.2026).

SB 544 amends Michigan's Insurance Code (MCL 500.2026) to prohibit insurers from changing coverage terms or denying claims after a claim is filed. Specifically, it bans "re-underwriting" a policy or altering coverage based on a claim that has been submitted, which directly protects policyholders from unfair treatment after filing a claim. The key provision (added as subsection (o)) prevents insurers from using claim history to deny coverage or increase premiums retroactively. This policy change ensures insurers must complete underwriting before issuing a policy, not after a claim arises. The bill aims to prevent insurers from unfairly penalizing customers who file legitimate claims.
