New Jersey Statutes Title 17B. Insurance 17B § 27-65

A health insurer which offers a group health plan may not require an individual, as a condition of enrollment or continued enrollment under the plan, to pay a premium or contribution which is greater than the premium or contribution for a similarly situated enrollee in the plan on the basis of any health status-related factor in relation to the individual or to an enrollee or a dependent of the individual or enrollee. This provision shall not be construed to restrict the amount that an employer may be charged for coverage under a group health plan or to prevent a health insurer offering group health insurance coverage from establishing premium discounts or modifying otherwise applicable copayments or deductibles in return for adherence to programs of health promotion and disease prevention.
