Is it true that policies in the exchange only charge for a maximum of three children on a family plan?

Q: I’ve heard that policies in the exchange only charge for a maximum of three children on a family plan. Is this true?

A: It depends on the ages of your children. A family policy can include separate child premiums for up to a maximum of three children age 20 or younger. There is no charge for additional children age 20 or younger. However, “adult children” age 21 to 25 who are covered on a family plan are charged the adult rate, regardless of how many dependent children a family has.

Family A has seven insured members: two parents in their 50s and five children, ages 18, 16, 15, 13, and 11.  Their total price will include premiums for the parents, plus premiums for three children, since all five children are 20 or younger.

Family B also has seven insured members: two parents in their 50s and five children, ages 24, 21, 17, 15, and 13.  This family’s premium will include charges for all seven family members. Adult rates will be charged for the parents and the two older children (rates vary based on age, so the parents’ premiums will be higher than the children in their early 20s.) And the three younger children will each be charged the applicable child rate (note that rates for children also vary based on age, as of 2018). If this family had a sixth child who was under 20, premiums would not be calculated for that child, as they have already reached the maximum of three.
