Quick answer
Save the denial notice and EOB, identify the reason, and follow the appeal instructions. Asking a question or requesting a corrected claim does not necessarily extend the appeal deadline.
Match the reason to the next question
| Reason shown | Useful next step |
|---|---|
| Missing or incorrect information | Ask the provider and plan what must be corrected or supplied. |
| Eligibility or effective date | Ask the administrator to compare enrollment records and coverage dates. |
| Authorization or network issue | Ask which requirement applied and whether any exception or review process is available. |
| Medical necessity or benefit exclusion | Request the specific plan provision and appeal instructions; ask the treating clinician for relevant support. |
Keep the deadline visible
Many group health plans provide at least 180 days to request an internal appeal, but the applicable rules and the notice need review. If a notice appears to offer less time than your rights allow, seek help promptly. Some urgent cases have expedited procedures. External review is available for qualifying decisions under applicable rules; it is not automatic for every type of denial.
Build a concise record
- The claim number, service date, denial notice, and latest EOB.
- Relevant plan language and the specific correction or review you are requesting.
- Supporting clinical information from your provider where needed.
- Dates, names, and reference numbers from calls, plus proof of submission.
Illustrative example
“Please explain the plan provision used to deny claim [number], the appeal deadline, and what information is needed for a review.”

If your employer works with Benefit Experts, we can assist with claims advocacy. We cannot guarantee payment or replace the plan’s formal appeal process. Use a secure channel for claim and medical details.
Washington OIC can help with plans it regulates and direct other questions to the appropriate agency. Many private-employer self-funded plans fall under federal DOL oversight; public and church plans can have different rules. Ask which type of plan you have.
Also contact the billing office about due dates while the matter is reviewed. Do not assume collections are automatically paused.
