How to Appeal a VA Disability Decision: HLR vs Supplemental Claim

Getting a VA disability decision that feels wrong is frustrating, but it’s also very common. The good news is that the VA built an entire appeal system specifically for situations like this.

Most veterans choose between two main appeal paths: a Higher-Level Review (HLR) or a Supplemental Claim. Each has different rules, timelines, and strategies, and choosing the right one can significantly impact your outcome.

This guide breaks down exactly how each option works and how to decide which one makes sense for your situation.

First: You Have One Year to Appeal

After the VA issues a rating decision, the clock starts immediately. You have one year from the decision date on your notification letter to file an appeal.

If you miss this deadline, your case usually closes and you may have to file a brand new claim. That can mean losing valuable back pay.

The two most common appeal options inside that one-year window are:

• Higher-Level Review (VA Form 20-0996)
• Supplemental Claim (VA Form 20-0995)
• Board Appeal (VA Form 10182)

Most veterans start with HLR or a Supplemental Claim because they are faster than going directly to the Board of Veterans’ Appeals.

What Is a Higher-Level Review (HLR)?

A Higher-Level Review asks the VA to have a more experienced reviewer re-evaluate your claim. This reviewer looks at the exact same evidence the original rater had.

You cannot submit new evidence with an HLR. Instead, the reviewer checks whether the VA made a mistake when applying the law or evaluating the evidence.

The request is submitted using VA Form 20-0996.

When a Higher-Level Review Makes Sense

HLR is ideal when the VA had the correct evidence but interpreted it incorrectly.

Common situations include:

• The VA ignored medical evidence already in your file
• The wrong diagnostic code was applied
• Your symptoms clearly match a higher rating but were underrated
• The VA denied service connection despite documented in-service events
• The VA failed to apply the benefit-of-the-doubt rule

In these cases, you don’t need new evidence. You just need a senior reviewer to fix the mistake.

Example: A veteran submits a PTSD claim with a VA C&P exam showing occupational impairment and severe symptoms. The VA assigns a 30% rating even though the exam findings match the criteria for 70%. An HLR can correct that error.

The Informal Conference Option

One powerful feature of HLR is the ability to request an informal conference. This is essentially a phone call with the higher-level reviewer.

During this call, you or your representative can point out the specific mistakes in the decision.

Common points raised during informal conferences include:

• Misinterpreted medical opinions
• Overlooked service treatment records
• Incorrect rating criteria application
• Missing secondary service connections

💡 Pro Tip: Before the informal conference, write down the exact page numbers or evidence you want the reviewer to look at. Specific references make your argument much stronger.

HLR Timelines

Higher-Level Reviews are generally faster than other appeal options.

Typical timelines look like this:

• Submission to decision: about 3–5 months
• Informal conference scheduling: often within 2–6 weeks
• Decision after conference: usually within a few weeks

If the reviewer finds a mistake, they may issue a Duty to Assist error. This sends the claim back for additional development such as a new medical exam.

What Is a Supplemental Claim?

A Supplemental Claim is used when you have new and relevant evidence that the VA did not previously consider.

This appeal option allows you to strengthen your case with additional documentation.

You submit it using VA Form 20-0995.

Examples of New and Relevant Evidence

The VA defines “new and relevant evidence” as information that was not part of your original claim file and could help prove your case.

Common examples include:

• A new medical nexus letter linking your condition to service
• Updated medical records showing worsening symptoms
• Buddy statements from fellow service members
• Private doctor evaluations
• Independent medical opinions (IMOs)
• New diagnostic test results

Example: The VA denies a migraine claim due to lack of a service connection. A veteran later obtains a neurologist’s nexus letter explaining how military burn pit exposure likely caused the condition. That evidence supports a Supplemental Claim.

When a Supplemental Claim Is the Better Choice

Choose a Supplemental Claim when your original denial happened because the VA lacked sufficient evidence.

This includes situations where:

• Your medical records were incomplete
• The VA exam was inadequate
• You didn’t submit a nexus letter
• Your condition worsened after the original decision
• You discovered new service records

Unlike HLR, Supplemental Claims allow the VA to consider fresh evidence that strengthens your argument.

Supplemental Claim Timelines

Supplemental Claims usually take slightly longer than HLR because the VA must review new evidence and sometimes schedule additional exams.

Typical timelines include:

• Average processing time: 4–6 months
• If a C&P exam is required: potentially longer
• Decision after exam: typically within several weeks

If approved, the VA usually preserves your original effective date as long as the appeal was filed within the one-year window.

HLR vs Supplemental Claim: Key Differences

The most important distinction is whether or not you have new evidence.

Higher-Level Review focuses on correcting mistakes. Supplemental Claims focus on adding stronger evidence.

• HLR form: VA Form 20-0996
• Supplemental form: VA Form 20-0995
• HLR evidence: no new evidence allowed
• Supplemental evidence: new and relevant evidence required
• HLR option: informal conference available
• Supplemental option: new exams or records may be added

Common Mistakes Veterans Make When Appealing

Many veterans accidentally weaken their appeal simply by choosing the wrong lane.

Some of the most common mistakes include:

• Filing HLR when new medical evidence exists
• Submitting duplicate evidence in a Supplemental Claim
• Missing the one-year appeal deadline
• Not reviewing the VA’s reasons for denial carefully
• Ignoring errors in C&P exams

⚠️ Watch Out: The VA explains exactly why your claim was denied in the “Reasons for Decision” section of the rating decision. Your appeal strategy should focus directly on those reasons.

How to Read the VA Decision Letter

Your rating decision contains clues about which appeal path will work best.

Look for these sections carefully:

• Evidence reviewed
• Reasons for decision
• Applicable diagnostic code
• Favorable findings

Favorable findings are particularly important. The VA is legally required to accept those facts in future appeals unless clear evidence proves otherwise.

That means you only need to focus on fixing the remaining problems.

Using Evidence Strategically

The strongest Supplemental Claims usually include targeted medical evidence that addresses the exact reason the VA denied the claim.

This often means obtaining a medical nexus letter from a qualified provider.

A strong nexus letter should include:

• A review of your service records
• A clear diagnosis
• A medical explanation linking your condition to service
• The phrase “at least as likely as not” (50% probability or greater)

Without this level of detail, the VA may dismiss the evidence as speculative.

How ClaimDuty Tools Can Help

Understanding VA decision letters is one of the hardest parts of the appeal process. Many veterans struggle to identify exactly what went wrong.

Tools like ClaimDuty help analyze rating decisions, highlight denial reasons, and identify evidence gaps that could strengthen an appeal.

This makes it easier to decide whether a Higher-Level Review or Supplemental Claim has the best chance of success.

💡 Pro Tip: Before filing an appeal, review your C&P exam report carefully. Many successful appeals focus on correcting flawed or incomplete VA examinations.

Can You Switch Appeal Lanes?

Yes. The modern VA appeals system allows veterans to move between review options if needed.

For example:

1. You file a Higher-Level Review.
2. The reviewer upholds the denial.
3. You then file a Supplemental Claim with new evidence.

This flexibility allows veterans to strengthen their case over time rather than being locked into one strategy.

When to Consider a Board Appeal Instead

If both HLR and Supplemental Claims fail, you can escalate your case to the Board of Veterans’ Appeals.

This requires VA Form 10182.

Board appeals allow you to request:

• A direct review by a Veterans Law Judge
• Submission of additional evidence
• A formal hearing

However, Board appeals often take significantly longer, sometimes 12–24 months or more.

Final Thoughts

A denied or underrated VA disability claim isn’t the end of the road. The appeals system exists because mistakes happen, and many veterans successfully increase their ratings through review.

The key is choosing the right path. Higher-Level Reviews correct errors, while Supplemental Claims strengthen weak evidence.

If you carefully analyze your decision letter, gather the right documentation, and file the correct form, you give your appeal the best chance of success—and protect the back pay you earned through your service.
