How each deadline is counted in Wyoming

Time to file

Wyoming law requires insurers to give you at least 30 days to ask the insurer to review a medical necessity denial. Federal rules give at least 180 days for most plans, and an insurer that follows the federal (ERISA) appeal rules is treated as complying with the Wyoming law. The deadline that applies to you is on your denial notice.

Law: Wyo. Stat. 26-40-201(c)-(d), (s)

Send your written request to your insurance company within 120 days after you receive the insurer's final written denial.

Keeping your benefits during the appeal

If you ask for a hearing before the effective date of the action on your notice, your Medicaid services cannot be ended or reduced until the final hearing decision (unless the hearing officer finds the only issue is federal or state law or policy).

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.
