Each group health plan shall provide benefits in accordance with the applicable requirements of any qualified medical child support order. A qualified medical child support order with respect to any participant or beneficiary shall be deemed to apply to each group health plan which has received such order, from which the participant or beneficiary is eligible to receive benefits, and with respect to which the requirements of paragraph (4) are met.
A medical child support order meets the requirements of this paragraph only if such order does not require a plan to provide any type or form of benefit, or any option, not otherwise provided under the plan, except to the extent necessary to meet the requirements of a law relating to medical child support described in section 1908 of the Social Security Act [42 U.S.C. 1396g–1] (as added by section 13822 1 of the Omnibus Budget Reconciliation Act of 1993).
If the plan administrator of a group health plan which is maintained by the employer of a noncustodial parent of a child or to which such an employer contributes receives an appropriately completed National Medical Support Notice promulgated pursuant to section 401(b) of the Child Support Performance and Incentive Act of 1998 in the case of such child, and the Notice meets the requirements of paragraphs (3) and (4), the Notice shall be deemed to be a qualified medical child support order in the case of such child.
Nothing in this subparagraph shall be construed as requiring a group health plan, upon receipt of a National Medical Support Notice, to provide benefits under the plan (or eligibility for such benefits) in addition to benefits (or eligibility for benefits) provided under the terms of the plan as of immediately before receipt of such Notice.
If a plan fiduciary acts in accordance with part 4 of this subtitle in treating a medical child support order as being (or not being) a qualified medical child support order, then the plan’s obligation to the participant and each alternate recipient shall be discharged to the extent of any payment made pursuant to such act of the fiduciary.
Any payment for benefits made by a group health plan pursuant to a medical child support order in reimbursement for expenses paid by an alternate recipient or an alternate recipient’s custodial parent or legal guardian shall be made to the alternate recipient or the alternate recipient’s custodial parent or legal guardian.
Payment of benefits by a group health plan to an official of a State or a political subdivision thereof whose name and address have been substituted for the address of an alternate recipient in a qualified medical child support order, pursuant to paragraph (3)(A), shall be treated, for purposes of this subchapter, as payment of benefits to the alternate recipient.
A group health plan shall provide that payment for benefits with respect to a participant under the plan will be made in accordance with any assignment of rights made by or on behalf of such participant or a beneficiary of the participant as required by a State plan for medical assistance approved under title XIX of the Social Security Act [42 U.S.C. 1396 et seq.] pursuant to section 1912(a)(1)(A) of such Act [42 U.S.C. 1396k(a)(1)(A)] (as in effect on August 10, 1993).
A group health plan shall provide that, in enrolling an individual as a participant or beneficiary or in determining or making any payments for benefits of an individual as a participant or beneficiary, the fact that the individual is eligible for or is provided medical assistance under a State plan for medical assistance approved under title XIX of the Social Security Act [42 U.S.C. 1396 et seq.] will not be taken into account.
A group health plan shall provide that, to the extent that payment has been made under a State plan for medical assistance approved under title XIX of the Social Security Act [42 U.S.C. 1396 et seq.] in any case in which a group health plan has a legal liability to make payment for items or services constituting such assistance, payment for benefits under the plan will be made in accordance with any State law which provides that the State has acquired the rights with respect to a participant to such payment for such items or services.
In any case in which a group health plan provides coverage for dependent children of participants or beneficiaries, such plan shall provide benefits to dependent children placed with participants or beneficiaries for adoption under the same terms and conditions as apply in the case of dependent children who are natural children of participants or beneficiaries under the plan, irrespective of whether the adoption has become final.
A group health plan may not restrict coverage under the plan of any dependent child adopted by a participant or beneficiary, or placed with a participant or beneficiary for adoption, solely on the basis of a preexisting condition of such child at the time that such child would otherwise become eligible for coverage under the plan, if the adoption or placement for adoption occurs while the participant or beneficiary is eligible for coverage under the plan.
The term “placement”, or being “placed”, for adoption, in connection with any placement for adoption of a child with any person, means the assumption and retention by such person of a legal obligation for total or partial support of such child in anticipation of adoption of such child. The child’s placement with such person terminates upon the termination of such legal obligation.
A group health plan may not reduce its coverage of the costs of pediatric vaccines (as defined under section 1928(h)(6) of the Social Security Act [42 U.S.C. 1396s(h)(6)] as amended by section 13830  of the Omnibus Budget Reconciliation Act of 1993) below the coverage it provided as of May 1, 1993.
