(1) Funds provided under the Pub. L. No. 99-457 grant may not be used to satisfy a financial commitment for services which would have been paid for from another public or private source but for the enactment of Pub. L. No. 99-457, except that, whenever considered necessary to prevent the delay in the receipt of appropriate early intervention services by the infant or toddler or family in a timely fashion, funds provided under this subchapter may be used to pay the provider of services pending reimbursement from the agency which has ultimate responsibility for the payment.
(2) 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, relating to maternal and child health, or Title XIX of the Social Security Act, relating to Medicaid for infants and toddlers with disabilities, within the state.
