How each deadline is counted in Oklahoma

Time to file

Oklahoma's insurance department pages do not set a longer time. Use the deadline on your denial notice; federal rules give at least 180 days for most plans.

Deadline to ask

You must file the External Review Request Form with the Oklahoma Insurance Department within 4 months after you receive your insurer's denial of a claim or of a request for a service or treatment.

Law: OID External Review Request Form (Rev. 11/2025)

The deadline runs from

The date you receive the insurer's denial (final internal appeal decision)

Hearing deadline

The date OHCA sends the written notice (the date on the notice is not counted; a mailed request counts as filed when OHCA receives it)

Keeping your benefits during the appeal

When you send a written hearing request, you can ask that your existing services continue or be restored until the appeal is dismissed, withdrawn or decided against you.

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.
