Dependent Coverage to Age 26

General (all payers)

Also called: adult child coverage; young adult on parent's plan; ACA dependent coverage

Why it matters: A young adult can be over the age of majority and still be a dependent on a parent's plan. The parent is the subscriber, the patient is the adult decision-maker, and statements can go to the wrong person. Verify the plan's rules, and use a confidential communications request when needed.
Illustrative example: A 22-year-old is a patient and a dependent on her father's plan. Her EOBs go to her father, so she asks to receive communications at her own address.

Definition: Essential health benefits are categories of services that the Affordable Care Act requires many individual and small-group plans to cover. Mental health and substance use disorder services, including behavioral health treatment, are one of the categories.
