The premium rates for an individual covered in a small employer plan may not exceed the premium rate for any other individual covered under the same small employer carrier because of age alone by a factor of 3:1. A small employer carrier may not require any individual to pay any premium or contribution that is greater than that for a similarly situated individual enrolled in the plan. Nothing in this section prohibits a group health plan, and a health insurance issuer offering group health insurance coverage, from establishing premium discounts or rebates or modifying otherwise applicable copayments or deductibles in return for adherence to programs of health promotion or disease prevention.
