Provides that automobile insurers may act as primary insurer and pursue claims against health insurers under certain circumstances.

This bill (S 3143) modifies New Jersey's auto insurance law to clarify coordination between automobile and health insurers after accidents. It allows auto insurers to pay for medical expenses upfront (acting as "primary insurer") when a policyholder has chosen health insurance as primary coverage, then seek reimbursement from the health insurer for amounts the health insurer should have covered. Auto insurers must notify the health insurer of this coverage selection and can recover reimbursed costs plus reasonable legal fees. The law applies to policies where the insured selected health insurance as primary and provides proof of health coverage, directly affecting auto and health insurers handling accident medical claims.
