Funds provided under section 1443 of this title may not be used to satisfy a financial commitment for services that would have been paid for from another public or private source, including any medical program administered by the Secretary of Defense, but for the enactment of this subchapter, except that whenever considered necessary to prevent a delay in the receipt of appropriate early intervention services by an infant, toddler, or family in a timely fashion, funds provided under section 1443 of this title may be used to pay the provider of services pending reimbursement from the agency that has ultimate responsibility for the payment.
If a public agency other than an educational agency fails to provide or pay for the services pursuant to an agreement required under paragraph (1), the local educational agency or State agency (as determined by the Chief Executive Officer or designee) shall provide or pay for the provision of such services to the child.
Such local educational agency or State agency is authorized to claim reimbursement for the services from the public agency that failed to provide or pay for such services and such public agency shall reimburse the local educational agency or State agency pursuant to the terms of the interagency agreement or other mechanism required under paragraph (1).
Nothing in this subchapter shall be construed to permit the State to reduce medical or other assistance available or to alter eligibility under title V of the Social Security Act [42 U.S.C. 701 et seq.] (relating to maternal and child health) or title XIX of the Social Security Act [42 U.S.C. 1396 et seq.] (relating to medicaid for infants or toddlers with disabilities) within the State.
