Medical claim denial appeals lets patients fight an insurer’s refusal to cover a procedure or prescription. Knowing this process gets you through the icky billing mud when a claim is denied.
To appeal, however, people need explicit instructions and paperwork for their particular case. Get ready to dive into actionable tips for filing an appeal, fighting to get coverage for necessary care in the U.S. Healthcare system.
Why Your Claim Was Denied
Often, claims denials occur due to easy-to-solve or well-known problems such as simple clerical mistakes, non-covered services, or a disagreement regarding medical necessity. Identifying the specific denial reason allows you to tackle the issue head-on.
Simple Errors
Occasionally, a claim denial comes down to a tiny error. Check all personal information entered on forms, such as your name, date of birth and health insurance number. Even one digit off can cause a denial.
Be sure to look for correct medical codes, such as CPT and ICD-10, that your provider employed. Mistakes in billing or coding is a common reason claims are denied.
Determine whether any pre-authorization or referral requirements were satisfied prior to your treatment. A lot of policies require pre-approval for specific services, such as surgery or certain tests, and a claim will be denied if this was skipped.
See if your coverage had lapsed or been terminated prior to the date of service.
Coverage Issues
Your claim was denied because the treatment or service you received isn’t covered. It is important to review your insurance policy’s summary of benefits and other plan materials.
These documents provide a detailed description of what services your plan covers, as well as any particular exclusions or limitations, like treatments that are deemed experimental or investigational.
You need to verify if the medical service is within your plan’s network — out-of-network care is a frequent cause for denial or increased expenses.
They can have to do with pre-existing condition clauses or waiting periods before certain benefits activate, or if your claim is beyond your policy’s maximum coverage amount or deductible.
Medical Necessity
A claim is denied when the medical necessity isn’t established. In other words, your insurer wonders whether the care was actually necessary to your health.
You need to know your insurer’s definition of “medical necessity” for the denied service. This definition is typically consistent with their internal clinical guidelines or criteria.
Get a letter from your doctor about why the treatment was important for you. This letter should specify the medical rationale.
Submit any medical records that support the procedure, medication, or therapy was necessary. That might be test results, failure of prior treatments, physician notes, etc.
Understanding why your claim was denied makes your next actions clear.
Your Fundamental Right to Appeal
Being denied a medical claim is hard, but knowing your rights is crucial. Your basic right to appeal any denied medical claim is not just a nice to have — it’s a safeguarded provision intended to provide you an avenue of redress when an insurer’s choice affects your well-being and wallet. Understanding health insurance claims denials can help you navigate this process more effectively.
Your right to appeal a denied claim is protected by federal and state laws. For example, the Affordable Care Act requires health insurance issuers in all states to conduct an external review and meet certain consumer protection standards effective as of January 1, 2012. This structure guarantees you means to appeal your assertion, providing essential claims denial data that can inform your next steps.
An appeal gives you a fresh evaluation of your initial claim to the insurer, and if still denied, you can have your appeal taken to an independent third party to examine that decision. If your health plan rejects your claim, pursuing an external review is fundamental to your right to appeal.
You may seek internal and external reviews. An internal appeal is where you request your insurance company to review its decision. So if your employer sponsors your health coverage, you may be required to make two internal appeals prior to being able to request an external review.
If the internal appeal doesn’t work, you can then go to an external review, where an independent organization looks at your case. File your written request for an external appeal within sixty days of the date your health insurer/health plan sent you a final decision denying your services or your claim for payment.
Know that you might only have sixty days in which to make this request. With a normal external review, we decide as quickly as possible and no later than 60 days after we receive your request. You can submit your own appeal, or you can designate another individual, such as a physician, lawyer, parent, or spouse, to act on your behalf throughout both the internal and external appeals.
Asserting your right to appeal is crucial, especially in understanding the denial reasons that may have led to your claim being denied initially.
The Medical Claim Denial Appeals Process

While a medical claim denial can be intimidating, patients have the right to appeal their health plan in the event a claim is denied or coverage is terminated. This process typically involves two main steps: an internal appeal with the health plan and, if needed, an external review by an independent third party.
Though often deep and arduous, knowing all stages of the medical claim denial appeals process arms you to seek coverage for required care. Here is a breakdown of the process:
1. Decode the Denial
Start by reading your denial letter to identify the specific reason for rejection. This letter contains key information, frequently referencing policy language, benefit exclusions, or insurer-used medical codes.
For instance, it might say the service was ‘not medically necessary’ or ‘experimental.’ Mark any appeals deadlines outlined in the denial notice. Missing them can put your ability to appeal the decision at risk. These deadlines are fierce, so time is often of the essence.
If it’s unclear why your claim is being denied after reading the letter, call your insurance company directly. Request clarification on the particular policy language or codes they reference. This step ensures you fully comprehend their stance before proceeding.
2. Gather Your Evidence
This is why compiling your documentation is key to a powerful appeal. This means getting copies of your full medical records, test results, and thorough doctor’s notes for the denied service.
For example, if a particular MRI was denied, collect all physician orders and radiologist reports for that scan. Obtain a detailed letter of medical necessity from your doctor. This letter should detail why the treatment or service was necessary for your condition, directly countering the insurer’s stated denial reason.
Be sure to include copies of your policy, summary of benefits, and the denial letter. Keep a detailed record of every call, including dates, persons spoken with, and summaries of conversations–with your insurer or doctors. This log becomes invaluable as your case moves forward.
3. Request an Internal Appeal
File a written appeal to your insurance company. This triggers the internal appeal process, where the health plan examines the denial for the new information you submit.
Write a letter explaining why you think the denial is incorrect and attach all of your supporting evidence collected. Be careful to meet your plan’s appeal deadlines, as internal appeals usually must be submitted within 180 days of the denial.
In addition, have your doctor’s office send a letter describing the medical necessity of the treatment directly to the insurance company.
4. Escalate to External Review
If your internal appeal is denied or unresolved, the important next step is to request an external review. This takes your case to an independent third party for a neutral examination of the denied claim.
This gives an impartial chance to make sure that the health plan’s decision is in accordance with medical necessity. Consult your state’s rules or federal guidance to determine whether your claim is eligible for external review.
Every state might have their own special twists for this part. For immediate medical necessity, you can seek an emergency external review. This route demands an answer within 72 hours, recognizing that some health needs simply can’t wait.
5. Understand the Timeline
Knowing the targeted deadlines to file both internal and external appeals is crucial to this process. Internal appeals typically have 180 days from the date you receive the denial. This will allow you time to formulate your argument.
External appeals typically accept up to four months from the date of the internal appeal denial. Be sure to put these dates on your calendar. Expect different decision times, which can vary depending on the complexity of the case.
Urgent cases frequently get quick decisions, in some cases within days. In other words, a winning appeal can turn a denial around and save you money.
Two Types of Claims Denial Appeals
Navigating a denied medical claim requires understanding the two primary avenues for challenging an insurer’s decision: internal appeals and external reviews. Patients have the right to appeal a health plan’s decision, whether that’s a denied claim or canceled coverage. Up to 86% of these denials are preventable, making a strong appeals process all the more important.
Each of these types of reviews is handled differently, requires different steps and information and if you want to pursue it, you need to understand them.
Feature | Internal Appeal | External Review |
|---|---|---|
Reviewer | Health insurance company (different personnel) | Independent Review Organization (IRO) |
Stage in Process | Typically the first step | Usually the second step, after internal appeal fails |
Decision | Made by insurer, may be overturned or upheld | Often binding on the insurance company |
Basis | Medical necessity, coverage terms, documentation provided | State or federal law criteria, impartial third-party assessment |
Internal Appeal
Internal appeals are usually the first step in challenging a denied medical claim. You file your first appeal with your health insurance company — asking them to reconsider. During this process, other staffers at the insurer look over your claim, usually a fresh crew that wasn’t behind the initial rejection.
You need to submit all documentation backing your claim’s medical necessity and coverage, including doctor’s notes, test results, and letters of medical necessity. For example, if a claim was denied because of missing information — a “soft denial” — you can resubmit it with the updated or additional supporting information.
You’ve filed your paperwork and now you wait for a response from your insurer, which finalizes the internal review, either affirming the denial or reversing it and approving the claim.
External Review
If your internal appeal doesn’t work, you can typically take your case to an external review. This means submitting your health insurance claim to an independent review organization (IRO), a third party non-affiliated with your insurance provider. A critical component of an external review is that the IRO’s decision is generally binding on the insurer, providing a layer of protection against unfair claims denials.
You must fall under the parameters for external review as defined by your state or federal legislation. For instance, some states demand that the denied service be medically necessary or experimental. When you bring your dispute to the IRO, it’s crucial to present compelling claims information — this is your chance to have a neutral third-party expert review the medical necessity and appropriateness of the denied service.
In summary, appeal types are key for claim denials.
The Unwritten Rules of Appealing
Tackling a medical claim denial isn’t just about the formal process, it’s about the unwritten rules. Read your denial letter carefully to see why you were denied. This early check is important for formatting your appeal.
The process typically has two levels: a first-level internal appeal with your insurance provider, and if denied again, a second-level external review handled by an independent third party. Keep in mind that these appeals timelines are inconsistent, with some plans providing as little as 60 days to get the ball rolling. Let this deadline pass and you’re surrendering your appeal rights.
Payers typically have to make internal appeal decisions within defined deadlines, such as 72 hours for urgent care, 30 days for care not yet provided, and 60 days for care already rendered. In some cases, you may request an expedited external review, with a decision within four business days.
The Human Element
Be polite to everyone and be clear about what you want, especially with insurance people. Keep in mind, the person on the other end is typically the gatekeeper for insights and subsequent actions.
Developing a relationship with customer service reps can grease the information flow. A courteous, helpful attitude can prompt them to provide you with additional explanations or point you to the most efficient avenues.
Be tenacious but polite with your follow-ups and inquiries. Remember that your case will be viewed by a human, not just a machine. Your respectful attitude can go a long way towards getting your appeal treated.
The Paper Trail
Keeping thorough documentation is key to backing your appeal in each phase. This documentation is your rock-solid proof. Your appeal-related documents folder should include:
- A copy of the original denial or cancellation letter.
- Copies of all submitted appeal letters and forms.
- All medical documentation — doctor’s notes, test results, prescriptions — backing up the medical necessity of the treatment.
- Carefully recorded notes from each call, including date and time, the name of the representative you spoke with, a reference number, if available, and a summary of talking points and agreed upon actions.
- Postal receipts, such as certified mail receipts, for any documents sent by mail.
Put all this evidence in chronological order. This careful note taking makes it easy for you to access information during conversations or when drafting later appeals, such as an external review.
The Doctor’s Role
Your doctor is frequently the key to a successful appeal. Request that your doctor send a vigorous letter of medical necessity for your treatment, explaining why the service was necessary for you. This letter should delineate the medical reasoning in straightforward, professional language.
Push your doctor’s office to call the insurance company for you. They frequently have established channels and a greater familiarity with medical coding and insurance processes that can speed things along. They can re-file corrected claims if an initial denial was due to a clerical or miscoding.
Effective appealing combines diligence, documentation, and diplomacy.
When You Need More Help
Even after exhausting internal appeal processes with your health plan, you may still have your medical claim denied. When it does, it’s time to seek outside help and expert advice.
Here are a few options These can include:
- State Departments of Insurance: These state-level agencies regulate insurance companies and can often help mediate disputes or investigate consumer complaints. For instance, if you reside in CA, you would reach out to the CA Department of Insurance.
- Patient Advocacy Groups: Non-profit organizations focused on specific conditions or patient rights can offer free or low-cost advice, resources, and sometimes direct assistance with appeals. Organizations like the Patient Advocate Foundation are fantastic.
- Healthcare Navigators or Ombudsmen: Some states or independent organizations offer services to help patients understand their rights, explore options, and file appeals.
- University-affiliated Legal Clinics: Certain law schools operate clinics that provide pro bono legal assistance for specific types of cases, including healthcare issues.
Look into legal representation, particularly if your claim represents a large dollar impact or very complex issues. A health lawyer can take a look at your case, help interpret policy language, and find possible violations of insurance law.
For example, if your denial is a high-dollar treatment for a chronic condition, or you think your insurer is being bad faith, lawyers can be key. They know the ins and outs of healthcare law and can assist you to seek external appeals or even litigation if needed.
If your health coverage is through your job, your employer’s HR department can be a great help. HR teams typically manage the relationship with the carrier and may have some insight on the plan’s specifics.
They can assist you in gaining access to plan documents, understanding benefits or even advocate on your behalf. This is particularly true for self-funded plans, which are often under different federal laws like ERISA, where HR can be key touch point.
Use consumer protection agencies as a guide on dealing with insurance battles. Agencies like your state Attorney General’s office or the FTC cover wider consumer complaints, such as unfair or deceptive insurance company practices.
They won’t necessarily assist with your specific claim, but they can provide guidance on your rights and where to file complaints. This can put additional pressure on the insurance to reconsider your claim.
In sum, outside assistance may be key for complicated claims denials.
Conclusion
A “medical claim” denial is a real problem. You have the right to appeal this decision. Familiarity with the appeals process is empowering. Gather together all your medical paperwork. Maintain good notes of each call and correspondence you send or receive. Follow each step for either an internal review or external review. If the work seems too much, enlist aid. There are a lot of organizations that focus on helping individuals with these appeals. Don’t throw in the towel. Strive for the health coverage you’re due.
