National rules that apply in every state

You have at least 180 days (about 6 months) from when you receive the denial notice to file an internal appeal. Your plan can give you more time, not less.

Law: 29 CFR 2560.503-1(h)(3)(i); 45 CFR 147.136(b)(2)(i), (b)(3)(i)

Under the federal process you have 4 months from the date you receive the denial or final appeal decision to ask for external review. If there is no matching date 4 months later, the deadline is the first day of the fifth month. If the last day is a Saturday, Sunday or federal holiday, it moves to the next business day. State programs must allow at least 4 months; some allow more.

Law: 45 CFR 147.136(c)(2)(vi), (d)(2)(i)

Your state must give you a reasonable time to ask for a fair hearing, up to 90 days from the date the notice was mailed. Check your notice: your state's deadline may be shorter.

Law: 42 CFR 431.221(d)

You generally have 90 days from the date of your Eligibility Notice to appeal. If you are late, explain why when you file; you may be able to get an extension.
