Wisconsin Claims Dispute & Statutory Guide
Wisconsin operates an At-Fault automobile insurance framework under Wis. Stat. § 632.32, requiring insurers to offer Medical Payments (MedPay) coverage of at least $1,000 per person unless rejected in writing. Claim payments are governed by strict prompt-pay rules with a 7.5% statutory interest rate under Wis. Stat. § 628.46, and hospitals protect balances using statutory liens under Wis. Stat. § 779.80.
Statutory Framework & Jurisdiction
Add-On PIP (Mandatory MedPay Offering & Prompt-Pay Statute)
Wisconsin enforces a modified comparative negligence tort system (51% bar) alongside mandatory offerings of first-party Medical Payments (MedPay) coverage. Under Wis. Stat. § 632.32(4)(a)2b, automobile liability policies must provide MedPay of at least $1,000 per person (often selected at $5,000 to $10,000 or higher) unless rejected in writing by the policyholder. Insurers are subject to strict prompt-pay timelines under Wis. Stat. § 628.46, requiring payment within 30 days of receiving written notice and proof of loss.

mandatory Med Pay Offering
$1,000 statutory minimum per person for medical, surgical, dental, ambulance, and hospital expenses, with higher optional limits commonly purchased (Wis. Stat. § 632.32(4)(a)2b)
written Rejection Requirement
Coverage is included in every automobile liability policy unless the named insured rejects MedPay in writing
collateral Source Rule

hospital Lien Statute
Under Wis. Stat. § 779.80, charitable and municipal hospitals have a statutory lien upon personal injury tort claims and recoveries. A written notice of lien must be filed with the clerk of circuit court in the county where hospital services were rendered before settlement proceeds are distributed.
