An HMO may not require an enrollee in a group health plan to pay a premium or contribution that is different from the premium or contribution for a similarly situated enrollee based on a health status-related factor. For purposes of this section, the term "similarly situated" has the meaning assigned to it in 45 CFR §146.121, relating to prohibiting discrimination against participants and beneficiaries based on a health factor. An HMO may not establish policies or procedures that are based on health status-related factors for the eligibility of any individual to enroll under a group plan.
