What Happens If Your Insurance Denies a Claim?
If your insurance denies claim, you can fight back: file an internal appeal, request an external review, and in some cases take legal action.
The process works like this:
- The insurer sends a denial letter explaining its reason
- You gather proof that the service or item is medically needed
- You file an appeal within the deadline stated in the letter
HealthCare.gov guide to internal appeals and external review explains these rights in plain terms.
Why Denials Happen: The Most Common Reasons
Most denials come down to paperwork, not policy. An insurance denial is your plan’s refusal to pay for an item it says is not covered or not proven necessary.
Common reasons include:
- Medical necessity: The insurer says the item is not needed
- Missing documentation: The claim lacked a prescription or records
- Coding errors: A wrong code was submitted
The good news: many of these are fixable.
Immediate Steps to Take After a Denial
Read the denial letter first, it names the reason and the appeal deadline. Then:
- Call your insurer and ask for the specific reason in writing
- Request a copy of your claim file
- Contact your doctor for supporting records
- Note the appeal deadline on your calendar
- Submit your appeal before that date
Ask your insurer for the exact policy language behind the denial. That citation often reveals a fixable gap, like a missing prior authorization, rather than a true exclusion.
How to Write an Insurance Appeal Letter That Gets Results
A strong appeal letter is short, factual, and backed by records. Learning how to write an insurance appeal letter starts with one rule: stick to the facts.
Your letter should state:
- Your name, member ID, and claim number
- The date of the denial
- Why you disagree, in one or two sentences
Keep it to one page. Attach proof. Send it by a method you can track.
What to Include in Your Appeal Letter
Include the prescription, your doctor’s notes, and any test results. Reference the medical necessity of the item, and add a letter of support from your doctor if possible.
Here is a simple template you can copy:
[Date]
To: [Insurer Name], Appeals Department
Re: Appeal of denied claim, Member ID [number], Claim [number]
I am appealing the denial dated [date] for [item or service]. My doctor, [name], prescribed this because [brief reason]. Attached are the prescription, office notes, and a letter of support. I request that you reverse this denial and cover the item as medically necessary.
Sincerely, [Your Name]
Send it to the address on the denial letter.
Medical Necessity Documentation for Insurance: Building Your Case
Medical necessity documentation for insurance ties your item to a real health need, the heart of most appeals.
Gather these records:
- The written prescription from your provider
- Office notes describing your condition
- A letter of medical necessity from your doctor
The burden of proof is on you. A clear paper trail wins far more appeals than a long emotional letter.
Sending an appeal without the prescription or doctor’s notes is the most common mistake. Without that documentation, the reviewer has nothing to reverse the denial, and the claim stays denied.
Internal Appeals vs. External Review: Understanding Your Options
There are two formal levels of appeal, and they are not interchangeable. The internal appeal is a second look by your own insurer; the external review is a decision by an independent reviewer. Both are free to you.
| Option | Who Reviews It | Typical Timing | When to Use It |
|---|---|---|---|
| Internal appeal | Your insurer’s appeals department | Usually within 30 to 60 days of the denial, depending on the plan | First step after any denial |
| Expedited internal appeal | Your insurer, fast-tracked | Usually within 72 hours when a delay would seriously jeopardize health | Urgent medical need |
| External review | Independent review organization | Requested after the internal appeal is exhausted | When the internal appeal upholds the denial |
| Expedited external review | Independent reviewer, fast-tracked | Usually within 72 hours | Urgent medical need after internal appeal |
How the Internal Appeal Works
You file the internal appeal in writing, using the address on the denial letter. The insurer must give you the specific reason for the denial and the policy language it relied on.
If the denial is based on medical necessity, you can usually request that a physician in the same specialty as your treating provider review the case, one of the most underused tools in the appeal process.
How External Review Works
If the internal appeal upholds the denial, you can usually request an external review. An independent review organization looks at the same records and issues a binding decision the insurer generally must follow.
Not every denial qualifies for external review. Denials based on medical necessity, experimental treatment, or rescission of coverage usually do; denials based purely on late premium payment often do not.
Deadlines You Cannot Miss
External review requests usually must be filed within four months of the final internal denial. Internal appeal deadlines vary by plan but are typically 180 days from the denial letter. Expedited reviews compress these windows to hours.
If you miss the external review window, you may lose the right to independent review entirely. Calendar the deadline the day the internal denial arrives, not the day you decide to act.
What Happens If You Win
If the external reviewer overturns the denial, the insurer must cover the item as if it had been approved originally. The claim is reprocessed, and any amount you paid out of pocket is typically reimbursed per your plan’s cost-sharing rules.

A Third Path: The Regulator
If the insurer misses a deadline, refuses to provide the policy language, or ignores the external reviewer’s decision, your state department of insurance can intervene. Filing a complaint is free and often produces a faster response than more internal paperwork.
Internal appeal first, external review second, regulator third. Each step has its own deadline, and each one builds the record for the next. For TRICARE members, we handle the authorization side so the appeal clock never starts in the first place.
TRICARE Breast Pump Coverage Requirements: What You Need to Know
TRICARE covers breast pumps for expecting and new mothers, and maternity back support when a provider prescribes it.
For TRICARE breast pump coverage requirements, the key points are:
- You need a prescription from your provider
- The pump must be medically necessary
- You must use a TRICARE-authorized supplier
A hands free breast pump is the practical choice for most mothers, it lets you pump while feeding, working, or caring for other children.
TRICARE breast pump and maternity supply coverage lists the current rules and covered items.
This is where General Home Medical Supply helps.
For TRICARE members, a prescription plus a TRICARE-authorized supplier is the winning combination. We handle both the authorization and the delivery, so you do not chase paperwork while recovering.
When to Hire an Attorney and How to Spot Bad Faith Practices
You rarely need a lawyer for a first-level internal appeal. Most reversals happen because the paperwork was incomplete, not because the insurer acted illegally. But there is a line where persistence stops working and legal pressure starts to matter.
Hire an attorney when any of these patterns appear:
- The insurer denies the same claim three or more times using different reasons each time
- It ignores records your doctor submitted and never explains why
- It misses a deadline the plan document or state law requires it to meet
The Legal Mechanism Behind a Denial
Most employer-sponsored plans are governed by ERISA. Under ERISA, you generally must exhaust the plan’s internal appeal process before you can sue.
Plans that are not ERISA-governed, individual market plans, Marketplace plans, and most government plans, fall under state insurance law instead. There, state bad faith rules can apply, and remedies can include damages beyond the denied benefit.
What Bad Faith Actually Means
Bad faith is not the same as a wrong denial. A wrong denial is a mistake; bad faith is when your insurance denies claim after claim through unreasonable delays, or fails to investigate a claim it had a duty to pay, for example, applying a blanket rule instead of reviewing your medical records.
Watch for these bad faith indicators:
- Shifting or contradictory reasons for the same denial
- Failure to send the denial in writing when required
- Refusal to provide the policy language the denial is based on
How to File a Complaint
Start with your state’s department of insurance. Filing a complaint is free. The department forwards it to the insurer and requires a written response, which alone sometimes reverses a denial because the insurer must now justify its decision to a regulator.
NAIC map of state insurance departments helps you find the right office.
If the item or service falls under a federally regulated plan, you can also file a complaint with the U.S. Department of Labor’s Employee Benefits Security Administration.
Keep a call log. Write down the date, the representative’s name, the reference number, and a one-line summary of what was said. If the case ever reaches a regulator or a courtroom, that log is evidence.
When an Attorney Is Worth It
An attorney is usually worth it when the denied benefit is large, the denial has repeated after a full appeal, or the insurer has clearly violated a deadline. Many ERISA and insurance attorneys offer a free consultation, and some work on contingency for bad faith claims.
If you have TRICARE and need a hands free breast pump or maternity back support, you usually will not reach this stage.

Frequently Asked Questions
Does a denied claim affect my future insurance coverage?
A denied claim itself does not automatically raise your premiums or cancel your policy. However, if the denial was due to incorrect information or a pattern of claims, it could impact future underwriting decisions. For medical equipment like breast pumps or maternity back support, a denial usually means you need to provide more documentation. General Home Medical Supply handles the authorization process to help prevent denials from affecting your coverage.
How long do I have to appeal a health insurance denial?
The deadline for internal appeals varies by plan and state, but many policies allow 180 days from the denial letter. External review deadlines can be shorter. Check your denial letter for the specific timeframe. If you are a TRICARE beneficiary, you generally have 90 days to file an appeal. Missing the deadline can forfeit your right to appeal, so act quickly and keep copies of everything you submit.
What information do I need to include in an insurance appeal letter?
Your appeal letter should include your name, policy number, claim number, date of denial, and a clear explanation of why you disagree. Attach supporting documents like a letter of medical necessity from your doctor, test results, or prescription. Reference the specific policy language or medical necessity criteria that apply. Keep it factual and concise. General Home Medical Supply can help gather the required documentation from your physician.
