Start with the paperwork
Identify the document you are reading
A health insurance denial notice and an explanation of benefits may be separate documents. A denial notice describes a decision and may include information about review rights or next steps. An EOB summarizes how a claim was processed; it is not necessarily the denial notice and is not necessarily a bill.
Compare the claim and service details before treating two documents as related. For help identifying common EOB sections, see the CMS guide to reading a health insurance EOB.
A document checklist
Common parts to look for
Notices vary. These details may appear in different places, and some may not be included in every notice.
Member, claim, and service references
Look for the member or policy reference, claim number, provider, service, and date of service, if shown. These details can help you match the notice to the right claim.
The decision and stated reason
Read the wording that explains what was denied or not paid and why. Keep the exact language nearby when you ask questions or review plan materials.
Codes and their explanations
A denial, reason, or remark code may appear with explanatory wording. Use both the code and its accompanying explanation; a code by itself may not explain the decision.
Dates
Note dates such as the notice date, service date, or claim-processing date if shown. The notice and current plan instructions are the places to check for dates that matter to your next step.
Plan terms and appeal instructions
The notice may cite a plan provision or explain appeal rights. If shown, look for a required form, submission method, and deadline, then compare those instructions with current plan materials.
If you have a question about a code, compare its wording with the denial-code guide. The code and the notice’s explanation should be read together.
A practical first read
A careful reading sequence
This is an organizing approach, not a universal appeal process or timeline. Follow the instructions that apply to your plan.
- 1Match the denial notice and any EOB to the same service and claim before comparing details.
- 2Copy the exact stated reason, claim or reference numbers, and any codes with their accompanying wording.
- 3Note every date and instruction in the notice, including any form, submission method, or deadline that is shown.
- 4Compare the notice wording with your current plan materials and the instructions for your plan.
- 5Ask the insurer or plan administrator named in your materials to clarify any requirement you do not understand.
- 6Keep copies of the notice, EOB, messages, forms, and records of when and how anything was submitted.
Use current, plan-specific instructions
Questions to check before taking action
Check your notice and current plan materials for the next step, any form, the submission method, and any deadline that applies. Do not assume one deadline or process fits every claim. If an instruction is unclear, ask the insurer or plan administrator named in your materials to explain what applies to your situation.
For general information about appealing an insurance company decision, read the HealthCare.gov appeal guide and CMS information on appeals of health plan decisions. Use the official instructions for your plan when deciding what to do.
Educational tools, with clear limits
Choose a next step
The free three-question orientation is educational and can help you consider what to check next. The Appeal Kit is a separate, paid document-organization product; its current details are on the pricing page. For help organizing an appeal letter, see the health insurance appeal letter guide.
This page and CairnClaim’s tools do not provide legal or medical advice, determine which rules apply to your situation, submit an appeal, or predict an appeal outcome.
Your notice and current plan instructions are the source for requirements and dates that apply to you.
