Start by getting the exact reason
Ask the insurer and the ordering office whether the issue is lack of prior authorization, missing clinical documentation, network status, coding, an exclusion or a determination about medical necessity. Request the written denial and the plan's appeal instructions. Coverage rules and deadlines differ by policy and insurance program.
If a test is being delayed, ask the clinician how urgent it is and whether another clinically appropriate diagnostic path can proceed while coverage is reviewed. Do not simply allow a recommended follow-up date to disappear from the calendar.
Work with the ordering clinician
- Identify the precise test or service. Get its name, ordering physician, diagnosis context and any referral or authorization number.
- Ask what clinical facts were included. The office may need to provide the relevant history, prior testing, risk factors, imaging or medical-necessity rationale.
- Request a peer-to-peer review when appropriate. Some plans allow the treating clinician to speak with the reviewing clinician. The ordering office can explain what is available.
- Track deadlines. Save the denial date, appeal deadline, contact number, case reference and the person responsible for the next action.
- Ask about expedited review if medically urgent. Eligibility depends on the circumstances and plan rules; the clinician can help document why waiting may be harmful.
Internal appeal and external review
Many health plans provide an internal appeal process and, for eligible disputes, an external review by an independent party. HealthCare.gov and CMS describe these rights, including when external review may be available. Medicare and Medicare Advantage have their own pathways and deadlines, so do not assume one set of rules applies to every insurance plan.
Use the insurer's actual denial letter and benefit documents to determine the next step. Patient advocates or state consumer assistance programs may also help explain the process. If an appeal is submitted, obtain confirmation it was received and a date to follow up.
A useful tracking sheet
| Record | Why it matters |
|---|---|
| Test/service requested and ordering clinician | Identifies exactly what is being reviewed. |
| Clinical reason and supporting records | Helps establish why the clinician requested the test. |
| Written denial reason and policy language | Shows what needs to be disputed or supplied. |
| Authorization or appeal case reference | Allows the insurer and office to find the same case. |
| Submission date, deadline and next call | Prevents administrative delays from becoming missed follow-up. |
| Clinical next-step date | Keeps the medical plan visible while coverage is resolved. |
Questions that keep the process moving
Ask the ordering office and insurer
- What specific evidence or policy criterion is missing?
- Has the ordering clinician received the full denial?
- Is there an opportunity to resubmit, seek peer review or file an appeal?
- Can the clinician document why this test is necessary in my circumstances?
- What is the appeal deadline, and who is tracking it?
- Is expedited review appropriate, and what happens clinically while we wait?
- If this is not covered, is there a clinically reasonable alternative?
Insurance coverage decisions do not determine what is medically appropriate. Equally, a requested test is not automatically necessary for every patient. The most effective challenge connects the specific clinical question to documentation and the plan's review rules.
