It depends on the type of plan you have, the urgency of your medical situation, and the level of appeal you're on. Under federal law (specifically ERISA for employer-sponsored plans), there are strict deadlines that both you and the plan must follow. Missing one of these deadlines can forfeit your right to appeal, so it's important to know how the clock works. WellthCare, the first Health-to-Wealth Benefit System, prevents this kind of frustrating process by providing $0-co-pay preventive care that is verified and rewarded, reducing the need for appeals entirely.
For employer-sponsored plans governed by ERISA (the Employee Retirement Income Security Act), you get 180 days to file an internal appeal. The plan then has 30 to 60 days to respond, depending on the claim type. If a second internal level exists, it runs on the same schedule, and external review can add up to 45 days. Urgent care claims move much faster. Each step is explained below.
Step 1: The Initial Denial Notification
The clock starts when you receive a formal denial notice, which ERISA calls an adverse benefit determination. The plan must decide your claim and send that notice within:
- 15 days for a pre-service claim (a request for prior approval of treatment), with one 15-day extension allowed
- 30 days for a post-service claim (reimbursement for care already received), with one 15-day extension allowed
- 72 hours for urgent care claims, with no extension allowed
If you don't receive a decision within those windows, treat the claim as denied and move to the next step. The date on the denial notice starts your appeal clock.
Step 2: Your First-Level Appeal (Internal Appeal)
You need to file your first appeal within 180 days (about six months) from the date you receive the denial. This is your chance to submit additional medical records, letters from your doctor, or other evidence. Don't wait until the last minute; gathering documentation takes time.
The plan then has:
- 30 days to respond for pre-service claims
- 60 days to respond for post-service claims
- 72 hours for urgent care claims
If the plan offers two levels of internal appeal, each level must be decided within 30 days. If the plan misses a deadline, you are treated as having exhausted your internal appeals, and you can go to external review or file a lawsuit.
Step 3: External Review
If your first appeal is denied, your plan may offer a second internal appeal level. If it does, you again have 180 days to file it, and the plan must decide it within 30 days. After you exhaust internal appeals (or if the plan misses a deadline), you can request an external review by an independent review organization, a right the Affordable Care Act gives to members of non-grandfathered plans. You have up to four months after the final internal denial to file the request. The independent reviewer, not the plan, must decide:
- 45 days for standard external reviews
- 72 hours for expedited external reviews
The reviewer is an independent third party, and its decision is binding on the plan.
Special Case: Urgent Care Claims
If your life or health is in immediate danger, the deadlines tighten. You may request an expedited appeal verbally or in writing. The plan must respond within 72 hours, or sooner if your condition requires it. Always note the urgency in your appeal request.
Plan Document Exceptions
Your plan's Summary Plan Description (SPD) may set timelines that are more generous than the federal minimums, but it can't shorten them. A self-funded ERISA plan can't cut your 180-day appeal window to 60 days; the regulation requires at least 180 days, and any provision that unduly limits your right to appeal is invalid. Always check your SPD for the exact dates, since the SPD must describe the claims procedures and their time frames. If your plan is not governed by ERISA (church plans, some government plans), state insurance law and plan terms set the timelines, which vary by state and plan.
When Your Appeal Clock Actually Starts
The 180-day clock runs from a valid denial notice, and not every denial letter qualifies. ERISA requires the notice to spell out the specific reasons for the denial, the plan provisions involved, what additional information you can submit, and a description of the review procedures and time limits. The notice must also tell you that you can get, free of charge, copies of all documents relevant to your claim.
If the plan asked you for more information before deciding, your appeal clock doesn't start until the period the notice gives you to submit that information ends. If a denial letter is missing any of the required elements, you can ask for a complete notice and treat the incomplete one as defective. Don't let a vague or incomplete letter start a clock it was never allowed to start.
What Happens If You Miss a Deadline?
If you miss the appeal deadline, you lose the right to pursue the claim administratively in most cases. Some plans accept a late appeal when you show good cause, such as serious illness, hospitalization, or an inability to gather records, but the plan is not required to. You may still file a lawsuit, but courts require a documented reason to excuse a missed deadline.
Practical Steps to Protect Your Rights
Missing a deadline is the easiest way to lose your appeal rights. Take these steps:
- Act immediately. As soon as you receive a denial, calendar every deadline.
- Request your full claim file from the plan. You have the right to receive it free of charge upon request.
- Get a supporting letter from your treating physician detailing medical necessity.
- Send all appeals via certified mail with return receipt to prove timeliness.
- Document everything: dates, names, and phone conversations.
Summary Table of Typical Timelines (ERISA Plans)
| Stage | Claim Type | Your Deadline | Plan or Reviewer Deadline |
|---|---|---|---|
| Initial decision | Pre-service | Not applicable | 15 days (one 15-day extension allowed) |
| Initial decision | Post-service | Not applicable | 30 days (one 15-day extension allowed) |
| Initial decision | Urgent | Not applicable | 72 hours (no extension) |
| Internal appeal (Level 1) | Pre-service | 180 days | 30 days |
| Internal appeal (Level 1) | Post-service | 180 days | 60 days |
| Second internal appeal (if offered) | Any | 180 days | 30 days |
| External review | Standard | 4 months to file | 45 days |
| External review (expedited) | Urgent | Verbally anytime | 72 hours |
If you file your internal appeal promptly, a pre-service claim can be decided in about a month and a post-service claim in about two months. If you wait until day 180 and the plan uses its full window, one appeal level can stretch to roughly eight months. Standard external review adds up to 45 days, while urgent cases can wrap up within 72 hours. Start immediately, and follow every deadline. Never assume a denial is final; you have more time and tools than most people realize.
