North Carolina General Statutes Chapter 58. Insurance § 58-50A-35. Premium contributions

(a) Neither an insurer nor a sponsoring association shall require any individual, as a condition of initial enrollment or continued enrollment in the plan, to pay a premium or contribution that is greater than the premium or contribution for a similarly situated individual enrolled in the plan on the basis of any health status--related factor in relation to the individual or to an individual enrolled in the plan as a spouse or dependent of the individual.

(b) Nothing in this section shall be construed to restrict the amount an insurer may charge for coverage under a group health plan offered to a sponsoring association under this section or to prevent an insurer from establishing premium discounts or modifying otherwise applicable co-payments or deductibles for a group health plan offered to a sponsoring association under this section in return for adherence to programs of health promotion and disease prevention.
