National Medical Support Notice

Complying with a National Medical Support Notice

Employers who receive a National Medical Support Notice (NMSN) must add the designated children to the employee’s health insurance plan if it meets the criteria.

To comply with a notice:

  1. Enroll the designated children according to the health insurance policy provisions.
  2. Forward insurance cards, and a copy of the description of coverage and effective dates, to the parent receiving support.
  3. Complete and return the “NMSN – Employer Response Section 3” and the “Notice to Employer” paperwork included in the packet you receive.

If enrollment is not possible, complete, and return the “NMSN – Employer Response Section 1” paperwork included in the packet you receive

If enrollment is not yet available, complete, and return the “NMSN – Employer Response Section 2.”

We recommend employers use the secure, free, online Oregon Employer Services Portal » to manage their obligations, including National Medical Support Notice responses.
