Form 3690C helps a person prove prior health coverage when Medicaid ends and they then apply for private or group health insurance coverage. This proof is used to reduce or eliminate any waiting period that may be imposed because of a preexisting condition.
When Medicaid coverage ends, Form 3690C is sent the week following the actual last day of the client's eligibility. Refer calls about Form 3690C to:
