CONCORD, N.H. (AP) — Thousands of New Hampshire Medicaid clients are receiving letters notifying them to pick one of three managed care plans as the state rolls out its managed care system. If Medicaid clients don't pick a plan, one will automatically be assigned to them beginning Nov. 12. If they aren't happy with their plan, they have 90 days to pick a different one. The plans take effect Dec. 1. Meridian Health Plan, New Hampshire Healthy Families and Well Sense Health Plan are offering plans. The state is urging Medicaid clients to check to see which of their current medical providers are in a plan if they want to keep using them.
