Higher-Level Review vs. Supplemental Claim: Which to File

By BilateralFactor Editorial Team · Published June 9, 2026

The core difference

Higher-Level Review and Supplemental Claim are both first-tier review options under the Appeals Modernization Act, but they serve opposite situations. The choice comes down to one question: do you have new evidence VA has never seen, or do you believe VA made an error on the record it already had?

Higher-Level Review (HLR): A senior adjudicator reviews the same record that supported the prior decision. No new evidence is permitted. The reviewer looks for legal or factual errors in the prior decision.

Supplemental Claim: A claims adjudicator reviews the prior record plus any new and relevant evidence you submit. New evidence is not just permitted; it is required for the claim to qualify as a Supplemental Claim.

Deadlines and forms

The 1-year rule for HLR is firm. If you miss it, HLR is no longer available and a Supplemental Claim or Board Appeal are the remaining options. For Supplemental Claims, there is no hard deadline, but effective-date preservation depends on how quickly you file after the prior decision.

Evidence rules in detail

Higher-Level Review: same record only

The record is frozen at the point of the prior decision. You cannot add medical records, buddy statements, new exam reports, or any other document. VA Form 20-0996 does not include an evidence submission section for this reason.

What HLR can do: the senior adjudicator looks at whether the prior decision correctly applied the law, the diagnostic criteria, and the combined-ratings math to the facts already in the file. If VA applied the wrong rating code, ignored a medical opinion that was already there, or made a calculation error under 38 CFR §4.25 or §4.26, HLR is the mechanism to correct it.

If VA skipped the 10% addition for paired extremity conditions (a bilateral factor omission), that is an error on the existing record. HLR is the right lane. You can verify the calculation using the combined ratings calculator and the bilateral factor tool before you file.

Supplemental Claim: new and relevant evidence required

VA defines new evidence as information it has not previously considered and relevant evidence as information that proves or disproves something in your claim. Both conditions must be met. Submitting old records VA already reviewed does not qualify.

Common examples of qualifying evidence:

• A private medical nexus opinion connecting a condition to service
• Buddy statements from fellow service members not previously submitted
• Updated VA treatment records documenting increased severity
• Newly obtained service personnel records or unit records

Duty to assist

Duty to assist applies in the Supplemental Claim lane. Once you file VA Form 20-0995, VA will attempt to gather records from VA medical centers and other federal facilities you identify. Provide the facility name and your dates of treatment. VA can also schedule a new C&P exam if the evidence warrants one.

Duty to assist also applies in HLR, but in a more limited way. If the HLR reviewer finds that VA failed in its duty to assist during the prior review (for example, by not obtaining records that were requested), the reviewer can identify corrective steps, gather the missing evidence, and re-decide based on the complete record.

The informal conference option (HLR only)

When you file VA Form 20-0996, you can request an informal conference. This is a phone call between you (or your representative) and the assigned senior reviewer. Its purpose is to identify the specific error in the prior decision: the wrong diagnostic code, the overlooked medical opinion, the missing calculation step.

Key rules:

• You can have only 1 informal conference per Higher-Level Review.
• The reviewer will attempt to reach you twice. If both attempts fail, the review proceeds without the conference.
• Requesting a conference may extend processing time somewhat.

No equivalent option exists in the Supplemental Claim lane. Your evidence submission does the work instead.

Processing timelines

VA’s processing target for HLR decisions on non-health-care benefit claims is 125 days (approximately 4 to 5 months), per VA.gov; a target is a goal, not a measured average. Supplemental Claims for disability compensation averaged 56 days in the same period. Board Appeals carry target timelines of 1 year (direct review), 1.5 years (evidence submission), or 2 years (hearing docket). Timelines fluctuate with VA’s workload; treat these as reference points, not guarantees.

What happens when you lose

If you lose a Higher-Level Review: You can file a Supplemental Claim with new and relevant evidence, or file a Board Appeal (VA Form 10182) within 1 year of the HLR decision. You cannot file another HLR on the same issue. The HLR decision is a new decision, so a Board Appeal filed within 1 year of the HLR decision is timely.

If you lose a Supplemental Claim: You can file another Supplemental Claim if you obtain additional new and relevant evidence, file an HLR if you believe the adjudicator made an error on the now-expanded record, or file a Board Appeal. Unlike HLR, there is no prohibition on filing successive Supplemental Claims.

Effective-date preservation

Winning a review generally preserves the effective date of the original claim. If VA grants an increased rating on HLR or grants service connection on a Supplemental Claim, back pay runs from the original effective date, not from the date of review. This matters significantly to the total retroactive payment. See VA disability back pay for how the amount is calculated.

The continuously-pursued-claim principle holds when you move from one lane to another within 1 year of each decision. Filing outside that window typically resets the effective date to the date of the new filing.

When each lane is the wrong choice

HLR is wrong when: You have evidence VA has never seen. Submit that evidence via Supplemental Claim instead; the HLR reviewer will not be able to consider it.

HLR is wrong when: You already lost an HLR or a Board Appeal on this issue. VA prohibits an HLR after either one on the same issue.

Supplemental Claim is wrong when: You have no new evidence. VA requires new and relevant evidence for a Supplemental Claim. Filing without it typically results in another denial.

Neither lane is adequate when: You want a hearing, you want a judge to decide, or the prior decision involves a legal interpretation that an adjudicator is unlikely to resolve in your favor. In those cases, the Board Appeal is the appropriate path.

Summary

HLR and Supplemental Claim address different problems. HLR corrects errors on the existing record without new evidence; the optional informal conference lets you identify those errors directly to the reviewer. Supplemental Claim introduces new and relevant evidence with VA’s duty to assist supporting the process. Both lanes generally preserve the original effective date when filed within 1 year of the prior decision. Losing either lane leaves the other available, along with the Board. HLR cannot follow another HLR or a Board Appeal on the same issue.
