(b) Where a policy of accident and health insurance, including a contract issued pursuant to article forty-three of this chapter, provides coverage for an early intervention program service, such coverage shall not be applied against any maximum annual or lifetime monetary limits set forth in such policy or contract. Visit limitations and other terms and conditions of the policy will continue to apply to early intervention services. However, any visits used for early intervention program services shall not reduce the number of visits otherwise available under the policy or contract for such services.

(c) Any right of subrogation to benefits which a municipality or provider is entitled in accordance with paragraph (d) of subdivision three of section twenty-five hundred fifty-nine of the public health law shall be valid and enforceable to the extent benefits are available under any accident and health insurance policy. The right of subrogation does not attach to insurance benefits paid or provided under any accident and health insurance policy prior to receipt by the insurer of written notice from the municipality or provider, as applicable. The insurer shall provide the municipality and service coordinator with information on the extent of benefits available to the covered person under such policy within fifteen days of the insurer's receipt of written request and notice authorizing such release. The service coordinator shall provide such information to the rendering provider assigned to provide services to the child.

(d) No insurer, including a health maintenance organization issued a certificate of authority under article forty-four of the public health law and a corporation organized under article forty-three of this chapter, shall refuse to issue an accident and health insurance policy or contract or refuse to renew an accident and health insurance policy or contract solely because the applicant or insured is receiving services under the early intervention program.
