National Medical Support Notice (NMSN) is a standardized form
developed by the federal government so that all states, employers, and plan administrators
have one, easily recognizable form that provides all information
needed for the employer to enroll dependent children in available employer–sponsored health insurance
coverage as ordered by the court.
The NMSN is a qualified medical child support order (QMCSO) that serves as notice to the employer and plan
administrator the employee identified on the document is obligated by a court or administrative child
support order to provide health care coverage for the child(ren) identified in it. The NMSN replaces any
notice or order that the issuing agency had previously served an employer.
Typically, the NMSN is sent to an employer when a state child support enforcement agency initially enforces the
employee’s medical support obligation or when an employee with a previously established medical support
obligation is newly hired. The NMSN can be issued for either the noncustodial parent or the custodial parent,
depending on the court order.
