For many private health plan denials, HealthCare.gov says you must file an internal appeal within 180 days of receiving the denial notice. Read the reason and plan term, request the claim file when available, add clinical or factual evidence, and state whether you want authorization, reprocessing, or payment. Urgent cases can use expedited review.
People facing denied imaging, medication, surgery, or hospital claims often ask what an appeal should contain beyond a doctor's note. The recurring failure is sending a general complaint without answering the insurer's stated denial reason or preserving the deadline.
Start here: a practical action plan
- Extract the denial reason and plan term.
- Calculate the deadline and file early.
- Index evidence that answers the stated reason.
- Verify authorization, payment, or external-review instructions.
- Sending a general complaint that never answers the denial reason.
- Using a draft date as proof of timely submission.
- Waiting on a standard review when the case qualifies as urgent.
Turn the denial notice into an appeal checklist
Read the denial notice for the claim, service, amount, reason code, plan provision, deadline, address, portal, and urgent-review instructions. A denial for missing authorization requires a different response from a denial based on medical necessity, exclusion, coding, or eligibility.
HealthCare.gov says an internal appeal generally must be filed within 180 days after receiving the denial notice. Use the plan's exact deadline and submission method. Save delivery proof because a drafted letter or portal screenshot without confirmation may not prove timely filing.
Worked example: calculate the 180-day window
Example: a patient receives a denial on May 12, 2026. Counting 180 calendar days makes November 8, 2026 the example outside date. The denied service is $9,600, so the appeal should identify that claim and amount rather than attaching an unexplained stack of records.
The date calculation is a planning example, not a substitute for the notice. Submit earlier because weekends, incomplete uploads, authorization records, and representative forms can delay acceptance. If the case involves urgent care, use the expedited process instead of waiting for the standard window.
| Hypothetical appeal record | Value |
|---|---|
| Denial received | May 12, 2026 |
| 180-day planning date | November 8, 2026 |
| Denied claim | $9,600 |
| Requested remedy | Authorize or reprocess the named claim |
Build evidence around the stated reason
Write the insurer's reason as a question the evidence must answer. For medical necessity, include the treating clinician's explanation, relevant history, prior treatment, and why the requested care meets the plan criteria. For a coding or administrative denial, include the corrected record and provider explanation.
Attach an index with page numbers and keep the original documents. Ask the plan to confirm receipt and whether anything is missing. A short, organized packet that addresses the controlling rule is easier to review than repeated calls with no shared record.
Track the decision and next review right
HealthCare.gov lists typical insurer decision timeframes of 15 days for prior authorization, 30 days for services already received, and 72 hours for urgent care, subject to the applicable rules. Record the promised decision date and follow up if it passes.
When the appeal is granted, verify authorization or claim reprocessing rather than assuming the bill vanished. When it is denied, save the final adverse determination and read the external-review instructions immediately because the next deadline can be measured in months.
- Extract the reason, plan term, deadline, and submission method.
- Calculate the 180-day date but file earlier.
- Answer the denial reason with indexed evidence.
- Verify the final authorization, payment, or external-review notice.
Frequently asked questions
How long do I have to file an internal appeal?
HealthCare.gov says many denials allow 180 days after you receive the denial notice. Follow the exact notice and plan rule.
What should the appeal request?
Name the service or claim and ask for a specific result, such as authorization, claim reprocessing, or payment under the plan.
Should I include every medical record?
Include records that answer the denial reason, with an index. A focused packet is usually clearer than unrelated records.
Can my clinician support the appeal?
Yes. A treating clinician can explain the diagnosis, prior treatment, urgency, and how the request meets the plan's criteria.
What if waiting could seriously harm me?
Use the plan's expedited urgent-care process. HealthCare.gov describes urgent decisions in 72 hours or less under applicable rules.
What happens after another denial?
Save the final adverse determination and immediately review eligibility and the deadline for an independent external review.
