Tool
Put in the date on your denial notice and pick the plan that denied you. You get the dates the published rules count to, with the rule and its source beside each one.
Read this first. These are dates the published rules produce, not advice about your case. We are not a law firm, an insurer or a government office. Your own notice governs: if it prints a deadline or a filing address, work to that one. Rules change, so check the sources before you rely on a date here.
The tool holds no numbers of its own. These are the windows behind it, each one carrying the document it was read from. Enter a date above and it counts from your date to these.
File your internal appeal with the plan
180 days
Counted from the day you received the plan's denial notice. This is the minimum the plan has to allow. Your plan may give you longer; it may not give you less.
“You have 180 days from receiving a denial to file an internal appeal with a commercial plan.”

Request external review by an independent organization
About four months
Counted from the date of the plan's final internal denial. This is the window the regulation sets.
“You have four months from the final internal denial to request an external review, and the independent reviewer's decision binds your plan.”

Request a fair hearing from the state
90 days
Counted from the date the notice of action was mailed. This is the outside limit. Your state is allowed to set a shorter window, and several do.
“Federal rules require the agency to allow a reasonable time, not to exceed 90 days from the date the notice of action is mailed, to request a hearing.”

It will not count to a date it cannot stand behind. Three cases come up often enough to name.
Every window above is the same sourced fact the procedure pages cite. There is one authored copy of each figure on this site and this page is a reader of it, not a second copy, so a date here cannot drift away from the document it came from. The procedures set out what to actually file on each route.
Denied and not sure which route is yours? Start on the denial page. If you are on Medicaid, the coverage matrix shows what each state we have read publishes.
Nothing here is medical or legal advice, and no date on this page is a prediction about your case. Every figure carries the document it came from and the month we read it.
