Deadline to ask

Keeping your benefits during the appeal

If you already have Medicaid or CHIP, your benefits continue at the old level if the regional office receives your hearing request within 10 days of the date of the notice.

If you miss a deadline

Medicaid

The 30-day period can be extended if you show good cause, as decided by the Division of Medicaid, as long as the facts of your case have not changed. Without good cause, a late request is not accepted, but you can reapply.
