(1) Health carriers shall be responsible for monitoring the status of their networks and must submit an updated access plan to the department within 30 calendar days after a significant change in the status of their network. For the purposes of this rule, a significant change is a change in the composition of a health carrier's provider network or a change in the size or demographic characteristics of the population enrolled with the health carrier that renders the health carrier's network non-compliant with one or more of the network adequacy standards set forth at ARM 37.108.215, 37.108.219 and 37.108.227. If the revised access plan is not submitted within 30 calendar days after the material change in network status occurs, the health carrier must cease enrolling new recipients in the affected geographic service area until the revised access plan is approved by the department. Review of the revised access plan is subject to the procedures and consequences outlined in ARM 37.108.205.

(2) In addition to the requirement in (1) above, the health carrier must submit an updated access plan to the department by at least 2 years after the date the carrier's access plan was last approved by the department.
