Supplemental Claim vs Higher-Level Review: Which One Should You File?

The VA denied your claim. Now what?

Under the Appeals Modernization Act (AMA), which took full effect in February 2019, veterans have three options for challenging a VA decision: file a Supplemental Claim, request a Higher-Level Review, or appeal to the Board of Veterans' Appeals. Each lane has different rules, timelines, and strategic implications.

This guide focuses on the two most common lanes: Supplemental Claims and Higher-Level Reviews. Choosing the wrong one can delay your benefits by a year or more. Choosing the right one can flip a denial into an approval without ever going to the Board.

What Is a Supplemental Claim?

A Supplemental Claim (VA Form 20-0995) allows you to submit new and relevant evidence — evidence that was not previously considered, or evidence that addresses the specific reason the VA denied your original claim.

"Relevant" under the AMA means evidence that tends to prove or disprove a point the VA had in dispute. A new private medical opinion, updated treatment records, a buddy statement that addresses a specific gap, or a nexus letter the VA never had — all of these qualify.

Key facts about Supplemental Claims:

• VA is required to assist you in gathering evidence (duty to assist applies)
• Any VA examiner can review your claim — it's not limited to a senior reviewer
• You can keep filing supplemental claims as long as you have new evidence
• Filing within one year of a decision preserves your effective date (and your back pay)
• Average processing time: 4–6 months

The Supplemental Claim lane is ideal when the original denial cited a specific evidentiary gap that you can now fill — for example, a missing nexus opinion, a condition that wasn't yet diagnosed, or service records that weren't in the file.

What Is a Higher-Level Review?

A Higher-Level Review (VA Form 20-0996) sends your file to a senior VA claims adjudicator who reviews the same evidence that was before the original rater. No new evidence is allowed.

Instead, the HLR looks for errors: a duty-to-assist failure, a factual inaccuracy, an incorrect application of the law, or a rating that didn't follow established criteria. The senior reviewer also has authority to call an informal conference — a phone call where your accredited VSO or attorney can point out specific errors in the original decision.

Key facts about Higher-Level Reviews:

• No new evidence is allowed
• Duty to assist errors are a valid ground for reversal
• The informal conference is optional but often valuable — request it
• The senior reviewer can increase, maintain, or even decrease your rating
• Filing within one year preserves your effective date
• Average processing time: 4–5 months

HLR is the right lane when the original rater made a clear mistake — they used the wrong diagnostic code, ignored medical evidence already in your file, or applied an incorrect rating criterion. If the evidence is already strong and the denial was based on process error, HLR gets you back pay faster.

Comparing the Two Lanes

| | Supplemental Claim | Higher-Level Review | |---|---|---| | New evidence allowed? | Yes | No | | Who reviews? | Any adjudicator | Senior adjudicator | | Duty to assist? | Yes | No | | Informal conference? | No | Yes (optional) | | Use when... | Evidence gap | Rater error |

The Decision Flowchart

Work through these questions in order:

1. Do you have new evidence that addresses the denial reason? If yes → file a Supplemental Claim.

2. Was the denial based on an error the rater made? Examples: wrong diagnostic code, evidence ignored, exam not ordered when required. If yes → file a Higher-Level Review, and request an informal conference.

3. Did neither of those options fit, or was your last Supplemental Claim also denied? Consider the Board of Veterans' Appeals. You can choose a direct review, evidence submission, or a hearing before a Veterans Law Judge.

4. Did an HLR deny you without new evidence available? The Board is the next step. Or, if new evidence has emerged since the HLR, you can file a Supplemental Claim off that HLR decision.

Common Mistakes to Avoid

Mixing lanes: Submitting new evidence with an HLR request. The senior reviewer will set the new evidence aside and evaluate only what was in the original file.

Missing the one-year window: Both lanes preserve your original effective date if filed within 365 days of the decision. After one year, you lose back pay to that original date — your new effective date becomes the date of your new claim.

Not requesting the informal conference on HLR: This free phone call gives your representative a chance to directly tell the senior reviewer what went wrong. Most representatives say it meaningfully improves outcomes.

Filing Supplemental Claims without strong evidence: A weak supplemental claim with marginally relevant evidence restarts the clock without fixing the underlying problem. Wait until your evidence is solid.

Filing the wrong form: VA Form 20-0995 is Supplemental Claim. VA Form 20-0996 is HLR. Submitting the wrong form can cause processing delays of months.

Which Should You File?

Choose Supplemental Claim if:

• You have new medical evidence, a private nexus opinion, or updated treatment records
• The denial said your condition wasn't service-connected and you now have a doctor willing to connect the dots
• You're still building your case

Choose Higher-Level Review if:

• Your file already contains strong evidence that the rater seems to have misread or ignored
• The VA owed you a C&P exam and didn't order one (a duty-to-assist failure)
• The diagnostic code or rating percentage applied was clearly wrong

In many cases, veterans file a Supplemental Claim to get new evidence in the record, then follow up with an HLR if the supplemental is denied despite solid evidence. The two lanes aren't mutually exclusive over time — you just can't combine them in a single filing.

Next Steps

Once you've identified your lane, gather your evidence before filing. For Supplemental Claims, a private nexus letter from a treating physician, updated medical records, and a personal statement are the most impactful additions. For HLR, pull the decision letter and annotate exactly which statements you believe are factual errors — then share that with your VSO or representative before requesting the informal conference.
