Quick answer: A birth or adoption opens a 60 day special enrollment period, well child visits from birth through age 21 are covered without cost sharing on most plans, and children who do not qualify for a family plan may be eligible for CHIP or Medicaid, which accept applications year round. Missing the first deadline is the most common and most costly mistake.
Nurturing care includes the paperwork. Here are the three dates that matter most in a child’s first year.
The 60 day window after birth or adoption
Having a baby triggers a special enrollment period. You can add the child to an existing plan or enroll in new Marketplace coverage outside of open enrollment, and coverage can be backdated to the day the baby was born.
The window is 60 days. Employer plans typically use a 30 day window, so check the plan document rather than assuming. Miss it and you may wait until the next open enrollment period.
Well child visits are already paid for
Most non grandfathered plans must cover preventive services for children with no copay or deductible. That includes well baby and well child visits from birth to age 21, immunizations, developmental screening, vision and hearing screening, and behavioral assessments.
The American Academy of Pediatrics schedule calls for numerous visits in the first three years. Those visits are how developmental delays get caught early, and for most families they cost nothing beyond the trip.
If a family plan is out of reach
Children’s coverage rates have moved in the wrong direction recently. Georgetown’s Center for Children and Families found the uninsured rate for children rose from 5.1 percent in 2022 to 6 percent in 2024, the highest in nearly a decade.
Medicaid and CHIP accept applications any time of year, with no enrollment window. Income limits are set by state and are higher than many parents expect, so it is worth applying rather than assuming you do not qualify. Families whose income sits above those thresholds can compare family coverage options against adding a child to an employer plan, since the cost difference can be significant.
Whatever route you take, put the 60 day date on the calendar before the baby arrives.
