The Municipal Reinsurance Health Insurance Fund or the MRHIF is a Joint Insurance Fund formed pursuant to NJSA 40A:10-36 et-Seq. The MRHIF was established in 1999 when its four original member regional Health Insurance Funds “HIF”s determined that additional cost savings could be achieved by pooling together to provide excess reinsurance and jointly purchasing on other health related services.

The MRHIF provides both Specific and Aggregate reinsurance coverage above its member “HIF”s Self Insured Retentions “SIR” for Medical and Prescription Drugs. The Fund has also procured TPA services, provider networks, Prescription Benefit Manager, wellness programs, enrollments systems and other related services on a joint purchase bases.

In addition to its HIF members the MRHIF will consider membership for self-insured local units that have at least 750 covered lives such as larger municipalities, Board of Educations, Counties etc.

As of 2023 the Fund includes Six regional local member HIFs, that insure over 290 Municipalities and/or School Districts in New Jersey.
