Statutory Framework & Jurisdiction

Applicable Legal System

At-Fault / Traditional Tort (Modified Comparative Fault & Indiana Hospital Lien Act)

Indiana does not require Personal Injury Protection (PIP) insurance. Medical costs resulting from auto crashes are billed to optional first-party Medical Payments (MedPay) coverage, health insurance, or third-party liability insurance maintained by the responsible driver. Under Ind. Code § 34-51-2-19, any subrogation claim by a MedPay insurer against a tort recovery must be diminished in proportion to the claimant's comparative fault and reduced by a pro-rata share of attorney fees. Hospitals secure unpaid balances through the Indiana Hospital Lien Act under Ind. Code § 32-33-4.
