There are few moments more frustrating for families than receiving an insurance denial. You believe a service is necessary. The doctor recommends it. The facility supports it. Then a letter arrives that says the insurance company will not pay.
It feels unfair and confusing, especially when your parent needs that service to stay safe, recover, or remain stable. What most families do not know is that denials are extremely common. What they also do not know is that denials are often overturned once the appeal process begins.
Appeals are not arguments. They are structured requests for a second review. When families understand how the system works, they win far more often than they lose.
This guide shows you exactly how to appeal a denial, what documentation matters most, why denials happen, and how to dramatically increase the chance of approval.

Part One Why Insurance Denials Happen More Often Than You Think
Insurance denials do not always mean the service is unnecessary. Denials usually happen for three predictable reasons.
Reason One Missing information
Many denials occur because the insurance company did not receive enough documentation to justify the service.
Common missing pieces include:
- Therapy evaluations
- Functional assessments
- Safety notes
- Daily living assistance needs
- Cognitive changes
- Medication management issues
If the insurance company does not see the need clearly, they assume the service is not necessary.
Reason Two Incorrect coding or wording
Healthcare providers use specific codes to describe medical needs. One small error can cause a denial. For example, if a service is coded as routine instead of medically necessary, coverage is denied automatically.
Wording matters too. If the chart does not reflect the reality of your parent’s needs, the insurance company will not approve services.
Reason Three Failure to meet technical requirements
Some services require:
- Prior authorization
- A qualifying hospital stay
- A doctor’s order
- Proof of homebound status
- Therapy progress notes
If any requirement is missing, the insurance system automatically denies the claim.
This is why appeals often succeed. The appeal adds what was missing.
Part Two The Types of Denials You Are Most Likely to Encounter
Understanding the type of denial helps you respond correctly.
Rehab denials
These happen when insurance believes your parent:
- Is not making progress
- Does not need skilled therapy
- Can receive care at home
- Does not meet criteria for skilled nursing
These denials are often overturned with better documentation.
Home health denials
These occur when the insurance company believes:
- The patient is not homebound
- The skilled need is unclear
- The frequency of visits is too high
- Therapy is no longer medically necessary
Appeals are effective when you show detailed safety concerns and functional changes.
Medication denials
Often caused by:
- Missing documentation
- Lack of prior authorization
- Step therapy requirements
- Incorrect coding
Doctors can strengthen these appeals quickly.
Equipment denials
Insurance may deny walkers, wheelchairs, or hospital beds if:
- The need is not documented
- The wording is unclear
- The wrong form is submitted
A clear physician statement usually fixes this.
Procedure or imaging denials
These usually require medical justification or prior authorization that was not submitted.
Most denials are reversible once the correct information is provided.
Part Three The Truth About Appeals Most Families Do Not Know
There are several truths that change everything once you understand them.
Truth One Appeals are expected
Insurance companies assume that families and providers will appeal. The first denial is often not the final answer.
Truth Two Appeals have stages
The first appeal is reviewed by the same company. Later appeals are reviewed by independent reviewers who often overturn the decision.
Truth Three You do not need legal help for most appeals
Most appeals are won with better medical documentation, not legal representation.
Truth Four Appeals have timelines
You must respond within the window listed in the denial letter.
Truth Five You can continue care during an appeal
For Medicare cases, families have the right to request a fast appeal which halts discharge until a review is complete.
Understanding these truths helps families feel more confident.
Part Four The Step-by-Step Process for Appealing an Insurance Denial
Here is the exact process that wins appeals.
Step One Read the denial letter slowly
The denial letter explains:
- Why the service was denied
- What information was missing
- How to submit an appeal
- Deadlines
- Required forms
This letter is your roadmap.
Step Two Request the full medical record
Ask the facility or doctor for:
- Nursing notes
- Therapy evaluations
- Daily progress notes
- Cognitive assessments
- Medication records
- Discharge summaries
These documents strengthen your case.
Step Three Identify what the insurance company did not see
Look for:
- Functional declines
- Falls
- Confusion
- Safety risks
- Mobility issues
- Wound care needs
- New diagnoses
- Pain that limits mobility
If these issues are not clearly documented, insurance assumes the service is not necessary.
Step Four Write a clear summary of your parent’s needs
This is the most important part of your appeal.
Include:
- Daily tasks your parent cannot complete
- Safety incidents
- Cognitive changes
- Medication errors
- Mobility struggles
- Bathroom issues
- Reasons they cannot return home safely
Your letter helps reviewers understand the real level of need.
Step Five Ask the doctor to write a supportive statement
Doctors can write short letters that include:
- Diagnosis
- Functional limitations
- Risks of not receiving the service
- Expected outcomes with the service
Strong physician statements win appeals.
Step Six Submit everything together
A strong appeal packet includes:
- Your appeal letter
- Doctor’s statement
- Therapy notes
- Nursing notes
- Assessments
- Relevant test results
- Medication lists
- Safety concerns
Submitting everything at once prevents delays.
Step Seven Request an expedited review
For hospital discharges, rehab decisions, and urgent cases, you can request a fast appeal. This forces the insurance company to review the case quickly.
Part Five How to Write a Strong Appeal Letter
Here is a simple structure that works.
Start with a clear statement
State that you are appealing the denial and list the specific service.
Explain the patient’s needs
Include:
- Functional limitations
- Cognitive changes
- Mobility issues
- Safety risks
Be specific but concise.
Explain the risks
Describe what will happen if the service is not provided.
Examples include:
- Falls
- Medication errors
- Confusion
- Unsafe discharge
- Medical decline
Reference supporting documentation
List the attached notes and assessments.
Ask for reconsideration
End with a polite request for approval.
This structure is direct and effective.
Part Six What Happens After You Submit the Appeal
Once the insurance company receives your appeal, they must:
- Review all documents
- Consider the doctor’s statement
- Contact the facility if needed
- Issue a new decision
Timeline varies by insurer and urgency, but Medicare decisions are often completed within a few days for fast appeals.
If the denial is overturned, coverage begins immediately.
If the denial is upheld, you can continue to the next level of appeal.
Many families win on the second level because independent reviewers take over.
Part Seven How to Win a Rehab Denial Appeal
Rehab denials are common. Here is how to win them.
Focus on functional progress
Include evidence of:
- Strength gains
- Balance improvements
- Mobility progress
- Ability to participate in therapy
Show why home is unsafe
Describe:
- Staircases
- Bathrooms without support
- Cognitive decline
- Limited caregiver availability
Include therapy notes
Therapists provide strong documentation that reviewers trust.
Part Eight How to Win a Home Health Denial Appeal
Home health denials often hinge on homebound status and skilled need.
Prove homebound status
Explain:
- Difficulty leaving home
- High fall risk
- Cognitive confusion
- Weakness
- Mobility issues
Prove skilled need
Include:
- Wound care requirements
- Medication management issues
- Therapy needs
- Monitoring needs
Documentation wins these appeals quickly.
Part Nine When You Should Ask for Professional Help
Appeals become complicated when:
- The denial is repeated
- The situation is urgent
- Multiple services were denied
- Your parent has complex medical needs
- Documentation is unclear
- You do not have time to manage the process
