RE:

This bulletin is issued in accordance with Sections 59-2-8, 59A-2-10, 59A-16-11(B) and 59A-46-
31 NMSA 1978, and 13.1.2 and 13.10.13.11(B)(2) NMAC.
The purpose of this bulletin is to clarify the position of the Office of Superintendent of Insurance

more than one health insurance plan. OSI will accept coordination of benefits language that is
consistent with Section 6(D)(2) of the NAIC’s Coordination of Benefits Model Regulation (No.

(i)
The plan of the parent whose birthday falls earlier in the calendar
year is the primary plan; or
(ii)
If both parents have the same birthday, the plan that has covered the
parent longest is the primary plan.
(b)
For a dependent child whose parents are divorced or separated or are not
living together, whether or not they have ever been married:
(i)
If a court decree states that one of the parents is responsible for the
dependent child’s health care expenses or health care coverage and
the plan of that parent has actual knowledge of those terms, that plan
is primary. If the parent with responsibility has no health care
coverage for the dependent child’s health care expenses, but that
parent’s spouse does, that parent’s spouse’s plan is the primary plan.
This item shall not apply with respect to any plan year during which
benefits are paid or provided before the entity has actual knowledge
of the court decree provision;
(ii)
If a court decree states that both parents are responsible for the
dependent child’s health care expenses or health care coverage, the
provisions of Subparagraph (a) of this paragraph shall determine the
order of benefits;
(iii)
If a court decree states that the parents have joint custody without
specifying that one parent has responsibility for the health care
expenses or health care coverage of the dependent child, the
provisions of Subparagraph (a) of this paragraph shall determine the
order of benefits; or If there is no court decree allocating
responsibility for the child’s health care expenses or health care
coverage, the order of benefits for the child are as follows:
(I)
The plan covering the custodial parent;
(II)
The plan covering the custodial parent’s spouse;
(III)
The plan covering the non-custodial parent; and then
(IV)
The plan covering the non-custodial parent’s spouse.

parent’s spouse; The plan covering the non-custodial parent; and then The
