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.

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.
