Okla. Stat. tit. 36, § 36-3203

A. All health benefit plans which provide coverage for a family

member of the insured or subscriber shall offer coverage for child

health supervision services. Such services shall include coverage

from the moment of birth through the age of eighteen years. Each

such plan or contract shall, at a minimum, provide benefits for

child health supervision services at approximately the following age

intervals: birth, two months, four months, six months, nine months,

twelve months, eighteen months, two years, three years, four years,

five years, six years, eight years, ten years, twelve years,

fourteen years, sixteen years and eighteen years. A health benefit

plan may provide that child health supervision services which are

rendered during a periodic review shall only be covered to the

extent that services are provided by or under the supervision of a

single physician or other primary health care provider during the

course of one visit. Benefits for such services shall be subject to

the same durational limits, dollar limits, deductibles and

coinsurance factors as other covered services in such health

insurance policies. All Oklahoma health benefit plans delivered,

issued for delivery, modified or renewed on or after January 1,

1995, shall be subject to the provisions of this section.

B. Nothing in the Oklahoma Child Health Insurance Reform Act

shall prohibit the health care insurer from including any or all

coverage for child health supervision services as standard coverage

in their policies or contracts.
