Enrollment in Medicare A shall not be a prerequisite for enrollment in any district health plan pursuant to this article. However, the purchase of Medicare B may be required for enrollment if the participant qualifies to purchase it. In addition, a district health plan may be restructured to pay benefits as if each participant is enrolled in Medicare B as soon as the participant qualifies to purchase Medicare B.

A health plan may condition eligibility for enrollment on the effective assignment of any Medicare benefits for which the enrollee would be eligible.
