(a) No plan contract that covers three or more enrollees shall exclude coverage for any individual on the basis of a preexisting condition provision for a period greater than six months following the individual's effective date of coverage. Preexisting condition provisions contained in plan contracts may relate only to conditions for which medical advice, diagnosis, care, or treatment, including use of prescription drugs, was recommended or received from a licensed health practitioner during the six months immediately preceding the effective date of coverage.
(b) No plan contract that covers one or two individuals shall exclude coverage on the basis of a preexisting condition provision for a period greater than 12 months following the individual's effective date of coverage, nor shall the plan limit or exclude coverage for a specific enrollee by type of illness, treatment, medical condition, or accident, except for satisfaction of a preexisting condition clause pursuant to this article. Preexisting condition provisions contained in plan contracts may relate only to conditions for which medical advice, diagnosis, care, or treatment, including use of prescription drugs, was recommended or received from a licensed health practitioner during the 12 months immediately preceding the effective date of coverage.
(c) A plan that does not utilize a preexisting condition provision may impose a waiting or affiliation period not to exceed 60 days, before the coverage issued subject to this article shall become effective. During the waiting or affiliation period, the plan is not required to provide health care services and no premium shall be charged to the subscriber or enrollee.
(d) A plan that does not utilize a preexisting condition provision in plan contracts that cover one or two individuals may impose a contract provision excluding coverage for waivered conditions. No plan may exclude coverage on the basis of a waivered condition for a period greater than 12 months following the individual's effective date of coverage. A waivered condition provision contained in plan contracts may relate only to conditions for which medical advice, diagnosis, care, or treatment, including use of prescription drugs, was recommended or received from a licensed health practitioner during the 12 months immediately preceding the effective date of coverage.
(e) In determining whether a preexisting condition provision, a waivered condition provision, or a waiting or affiliation period applies to any enrollee, a plan shall credit the time the enrollee was covered under creditable coverage, provided that the enrollee becomes eligible for coverage under the succeeding plan contract within 62 days of termination of prior coverage, exclusive of any waiting or affiliation period, and applies for coverage under the succeeding plan within the applicable enrollment period. A plan shall also credit any time that an eligible employee must wait before enrolling in the plan, including any postenrollment or employer-imposed waiting or affiliation period.
However, if a person's employment has ended, the availability of health coverage offered through employment or sponsored by an employer has terminated, or an employer's contribution toward health coverage has terminated, a plan shall credit the time the person was covered under creditable coverage if the person becomes eligible for health coverage offered through employment or sponsored by an employer within 180 days, exclusive of any waiting or affiliation period, and applies for coverage under the succeeding plan contract within the applicable enrollment period.
(f) No plan shall exclude late enrollees from coverage for more than 12 months from the date of the late enrollee's application for coverage. No plan shall require any premium or other periodic charge to be paid by or on behalf of a late enrollee during the period of exclusion from coverage permitted by this subdivision.
(g) A health care service plan issuing group coverage may not impose a preexisting condition exclusion upon the following:
(1) A newborn individual, who, as of the last day of the 30-day period beginning with the date of birth, has applied for coverage through the employer-sponsored plan.
(2) A child who is adopted or placed for adoption before attaining 18 years of age and who, as of the last day of the 30-day period beginning with the date of adoption or placement for adoption, is covered under creditable coverage and applies for coverage through the employer-sponsored plan. This provision shall not apply if, for 63 continuous days, the child is not covered under any creditable coverage.
(3) A condition relating to benefits for pregnancy or maternity care.
(h) An individual's period of creditable coverage shall be certified pursuant to subsection (e) of Section 2701 of Title XXVII of the federal Public Health Services Act (42 U.S.C. Sec. 300gg(e)).
