I won't bill you for this bit of advise, but have your employer research ERISA Section 609(c)(1). (This refers to group health insurance plans, not private plans and has been the law of the land for many years now.)
"In general, section 609(c)(1) requires group health plans that provide coverage for dependent children to provide such coverage to children who are placed for adoption with participants or beneficiaries, with coverage being effective upon such placement.2 Benefits must be provided under the same terms and conditions that apply to dependent children who are natural children of participants or beneficiaries under the plan, irrespective of whether the adoption has become final. Section 609(c)(2) provides that a group health plan may not restrict coverage under the plan of any dependent child adopted by or placed for adoption with a participant or beneficiary solely on the basis of a preexisting condition of such child at the time the 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," Robert J.
