When a member is approved for Medicaid, they are assigned to a Managed Care Organization (MCO) and dental plan (MCO) unless they qualify for services under a Fee-for-Service (FFS) program. Members have 90 days from their initial enrollment to change their MCO or their dental plan for any reason.

After a member has been with an MCO or dental plan for 12 months, they may change their MCO or dental plan for any reason during their annual Open Choice period.

  • Members who wish to change their MCO during their initial enrollment period or during their Open Choice period may use the MCO Change form to submit their choice. 
  • Members who wish to change their dental plan during their initial enrollment or during their Open Choice period may use the Dental Carrier Change form to submit their choice. 
  • Members who wish to keep their current MCO or dental plan do NOT need to take any action to keep their current plans.  

Outside of a member's initial enrollment and their Open Choice period, they may only change MCOs for reasons of Good Cause.
