Welcome to the New Jersey National Medical Support Notice Processing Center

The National Medical Support Notice (NMSN) is a two-part notice sent to employers from a local child support agency. Its purpose is to ensure that children receive health care coverage when it's available and required as part of a child support order.

Employers and health plan administrators are required to complete and comply with the National Medical Support Notice (NMSN) and respond within 20 days of receipt. Please use this site for information about National Medical Support Notices and to conveniently respond online!
