Your VA claim was denied — or rated lower than you deserve. You have three appeal lanes under the Appeals Modernization Act: Supplemental Claim, Higher-Level Review, and Board of Veterans' Appeals. Two of them are fast. One of them is right for your situation. Here's how to tell which is which.
The VA publishes appeal processing data through its Board of Veterans' Appeals Annual Reports and VBA Monday Morning Workload Reports. Based on 2024–2025 data, the average processing times for the two fast appeal lanes are:
On speed alone, HLR wins by about ten days. But this headline number is deceptive. Choosing HLR when you need Supplemental Claim — or vice versa — means getting a denial and having to start over in the correct lane, adding months to your appeal timeline rather than saving days.
The fastest appeal is the one that leads to a favorable decision in one round. Choosing the wrong lane and needing a second appeal is always slower than choosing the right lane and winning the first time — even if the right lane averages 10 more days.
A Higher-Level Review (HLR) is an appeal filed on VA Form 20-0996. It asks a more senior VA claims adjudicator — a higher-level reviewer — to look at your existing claims file and identify whether a clear and unmistakable error (CUE) was made in the original decision.
The critical constraint: you cannot submit new evidence with an HLR. The reviewer looks only at the record that existed when the original decision was made. If you need new medical evidence, new nexus letters, or a new C&P exam to win, HLR cannot help you — the reviewer will simply uphold the original decision based on the same record.
What HLR can do is catch errors the original rater made: applying the wrong diagnostic code, ignoring evidence that was already in the file, making a math error in the combined rating calculation, or failing in the duty to assist (e.g., not obtaining records you requested).
One exclusive feature of HLR is the informal conference — a 30-minute phone call with the higher-level reviewer before they complete their review. This is discussed in detail below. It's one of the most underused tools in the VA appeals process.
A Supplemental Claim is an appeal filed on VA Form 20-0995. It allows you to submit new and relevant evidence that was not part of the original claim decision. The VA must then conduct a de novo (fresh) review of your claim with the new evidence included.
The threshold: the new evidence must be relevant to the issue being appealed. A private nexus letter, a new diagnosis from a private specialist, buddy statements from fellow service members, treatment records that weren't in the file, or a more detailed personal statement can all qualify as new and relevant evidence for a Supplemental Claim.
Supplemental Claims also trigger VA's duty to assist again. If you need a new C&P exam — because the original exam was inadequate, or because your condition has worsened — filing a Supplemental Claim is the pathway that can get you that exam. HLR does not trigger a new C&P exam.
Choose HLR when your situation involves an error in the original decision rather than a gap in evidence. Specific scenarios where HLR is the right call:
Choose Supplemental Claim when the original denial was based on insufficient evidence — not an error in evaluating the evidence that existed.
Filing an HLR when you need new evidence is the most common appeal lane error. The higher-level reviewer cannot consider anything that wasn't in the original file. If your original claim was denied because of weak evidence, HLR will produce the same denial — faster, but still wrong.
Yes — and this is a legitimate advanced strategy, but only when you have different issues within the same claim.
The rules prohibit filing HLR and Supplemental Claim on the exact same issue simultaneously. But many rating decisions involve multiple issues: the denial of service connection on one condition, a lower-than-warranted rating on another, and an incorrect effective date on a third.
In this scenario, you can file:
Filing on different issues simultaneously can compress your overall timeline. You may get the effective date corrected via HLR while building your evidence package for the rating increase via Supplemental Claim — rather than completing one appeal before beginning the other.
This is one area where having a good VSO or claims agent review your decision letter is particularly valuable: they can identify which issues are ripe for each lane.
One of the most costly mistakes in VA appeals is losing your original effective date. Your effective date determines how far back your retroactive benefits go — and the difference between preserving and losing a multi-year effective date window can be tens of thousands of dollars.
The rules under the Appeals Modernization Act:
Count your one-year clock from the date printed on your rating decision letter. Do not assume you have more time than you do. Filing even one day late on an effective date issue can cost years of retroactive benefits. Use our denial analyzer to confirm your deadline.
The Appeals Modernization Act created a flexible system where you can move between lanes after a denial. Understanding the pathways prevents you from feeling trapped:
If your HLR results in a new denial (or a continued decision you disagree with), you can:
If your Supplemental Claim produces an unfavorable decision, you can:
Do you have new evidence — a nexus letter, new diagnosis, buddy statements, or unreported treatment records?
→ Yes: File Supplemental Claim (VA Form 20-0995)
→ No: Continue to step 2
Is there a clear error in the original decision — wrong diagnostic code, ignored evidence, math error, or duty to assist failure?
→ Yes: File Higher-Level Review (VA Form 20-0996)
→ No: Continue to step 3
Do you need a new C&P exam, or was the original exam inadequate?
→ Yes: File Supplemental Claim — only this lane triggers new VA duty to assist including C&P exams
→ No: Continue to step 4
Have you already tried one lane without success?
→ Failed HLR: file Supplemental with new evidence, or go to BVA
→ Failed Supplemental: consider HLR if rater made an error, or go to BVA
When you file an HLR, you have the option to request an informal conference with the higher-level reviewer. This is a 30-minute phone call — not a formal hearing — where you can explain your position on the specific errors you believe the original rater made.
Most veterans don't request this conference. That's a significant missed opportunity.
The informal conference is not an evidentiary hearing. You cannot submit new documents, bring witnesses, or introduce new arguments outside the existing record. But it gives you a direct channel to explain to the reviewer what you believe was missed or misapplied in the original decision:
Higher-level reviewers are experienced adjudicators. A clear, focused explanation of the specific error — grounded in the actual file contents — can make the difference between an upheld denial and a favorable decision.
When filing your HLR (VA Form 20-0996), check the box requesting an informal conference and provide a phone number where you can be reached. The VA will call you before the reviewer makes their decision. Prepare a written outline of the specific errors you're disputing — keep it focused on 2–3 clear points, not a broad retelling of your entire service history.
| Factor | Higher-Level Review | Supplemental Claim |
|---|---|---|
| Average processing time | 73 days | 83 days |
| New evidence allowed? | ❌ No | ✅ Yes |
| New C&P exam possible? | ❌ No | ✅ Yes |
| Informal conference option | ✅ Yes | ❌ No |
| Use when | Clear error in original decision | New evidence available |
| Preserves effective date | ✅ Within 1 year | ✅ Within 1 year |
| VA duty to assist | Limited (existing record) | Full (new evidence) |
| Form | VA Form 20-0996 | VA Form 20-0995 |
HLR is 10 days faster on average. But choosing HLR without a clear error in the file — or choosing Supplemental without new evidence — simply resets your clock after the wrong-lane denial. Match the lane to your situation: new evidence goes in Supplemental Claim, clear errors go in HLR. When in doubt, use the decision tree above and our denial analyzer to identify the strongest pathway.
