Yes. You are still eligible to be covered as a dependent. Your parent’s plan must offer you a special opportunity to re-enroll if the coverage you lost was considered “minimum essential coverage.” That special enrollment period must last at least 30 days from the date you lost other coverage. You may also qualify for a special enrollment period if you lost Medicaid or CHIP coverage in the past 60 days. (45 C.F.R. § 147.120; 45 C.F.R. § 146.117).
