How Medicaid and CHIP Work for New Families

Part of the Learning Center · included with every paid plan

Medicaid finances about 4 in 10 births in the United States, more than any single private insurer. The program's income thresholds for pregnant women and children reach far higher than many families expect: a household earning well into the moderate-income range may still qualify. A set of federal rules then activates automatically at birth to protect the newborn's coverage, and a recent extension keeps the parent covered for a full year after delivery. This guide maps who is eligible, how to apply, what happens at birth, and how Medicaid works alongside employer insurance.

What this guide covers

· The coverage landscape: how Medicaid and CHIP fit together
· Who qualifies: income, family size, and the counting rules
· How to apply (and how fast coverage can start)
· The deemed-newborn rule: automatic coverage at birth
· The twelve-month postpartum extension
· When Medicaid and employer coverage overlap
· CHIP: the children's coverage layer
· Where the plan comes in

The full guide comes with your plan.

Every Mothers Plan includes the Learning Center: the knowledge behind each task on your personalized, dated timeline.
