CONCORD, N.H. (AP) — Medical copayments will increase on Jan. 1 for people on the state’s Medicaid expansion plan with incomes higher than twice the federal poverty line, which is roughly $12,000 for an individual.

The Joint Legislative Fiscal Committee approved the change Friday. Roughly 13,000 of the 44,000 people on Medicaid expansion will be affected by the copay increases. An additional 5,500 people on traditional Medicaid who earn double the poverty line will be subject to the higher copays.

State health officials said the increases are due to actuarial changes. New Hampshire’s Medicaid expansion plan relies on using federal dollars to put low-income people on private health insurance plans. The change puts maximum copays at $588 per year.
