Hamill v. Collins: No More Implicit TDIU Denial Under the AMA
Posted by Gregory M. Rada | March 10, 2026 | Disability Compensation
On February 4, 2026, the U.S. Court of Appeals for the Federal Circuit issued its decision in Hamill v. Collins, No. 24-1543, and it may be the most significant veterans law opinion in years for anyone with a pending or overlooked TDIU claim. The court held that the implicit denial doctrine no longer applies to claims decided under the Appeals Modernization Act (AMA). In plain terms, if VA didn’t explicitly identify and decide a claim in its decision notice, that claim was never adjudicated and it may still be pending. For veterans who were reasonably entitled to TDIU but never received an express decision on it, this ruling could open the door to substantially earlier effective dates and significant retroactive compensation.

What Was the Implicit Denial Doctrine?
Before Hamill, courts recognized a judicially created rule called the implicit denial doctrine. Under this rule, VA could effectively deny a claim without ever mentioning it in a decision as long as a “reasonable person” would understand that a related decision was intended to dispose of the unmentioned claim as well. The doctrine was established in Adams v. Shinseki, 568 F.3d 956 (Fed. Cir. 2009), and applied across a range of situations.
Here’s how it worked in practice. A veteran might file a claim for a disability, and during the claim, VA would become aware that the veteran potentially could not work due to that disability. VA would issue a decision on the disability but say nothing about TDIU. Under the implicit denial rule, VA could later argue that the TDIU claim was “implicitly denied” by the other decisions meaning the veteran’s appeal clock started running on a denial they were never told about.
The result was predictable: veterans lost appellate rights on claims they didn’t even know had been decided. And the doctrine was especially damaging in the TDIU context, where the claim is often raised by the evidence in the file rather than by the veteran’s own formal application.
What Happened in Hamill v. Collins?
David Hamill served in the Marine Corps from 2009 to 2013 and was discharged under Other Than Honorable conditions. He filed for disability compensation, and VA denied his claim in 2014 based on his character of discharge. He tried again in 2017 and 2021, each time raising the question of whether his discharge should be reconsidered.
In 2021, VA granted service connection for PTSD but completely ignored the character-of-discharge question. No mention. No decision. Nothing.
Hamill’s attorney asked VA to actually decide the discharge issue. VA punted. Hamill then petitioned the Court of Appeals for Veterans Claims (CAVC) for a writ of mandamus essentially asking the court to order VA to do its job. The CAVC dismissed the petition, ruling that VA had “implicitly denied” the discharge claim in its 2021 decision.
The Federal Circuit reversed. Chief Judge Moore, writing for a unanimous panel, held that the AMA’s enhanced notice requirements are fundamentally incompatible with the implicit denial doctrine. Under the AMA, VA can no longer silently deny claims.
Why the Federal Circuit Eliminated Implicit Denial Under the AMA
The court’s reasoning centers on what Congress did when it enacted the AMA in 2017 (Pub. L. No. 115-55). The old VA appeals system had a single path and relatively thin notice requirements. The AMA overhauled that structure, giving veterans multiple review lanes higher-level review, supplemental claims, and three Board of Veterans’ Appeals dockets and deliberately strengthened the notice requirements that accompany VA decisions.
Under 38 U.S.C. § 5104(b), VA decision notices under the AMA must now identify the issues adjudicated, summarize the evidence considered, list the applicable laws and regulations, identify favorable findings, and for denials explain which elements of the claim were not established. These aren’t suggestions. They’re statutory mandates.
The Federal Circuit concluded that these heightened notice requirements exist precisely because veterans need clear, explicit information about what VA decided in order to choose the right review lane. A veteran can’t meaningfully choose between a higher-level review, a supplemental claim, or a Board appeal if they don’t know which issues were actually decided.
The court put it directly: under the AMA, a veteran has an appealable decision for a particular issue only if the decision gives the veteran explicit notice that the issue is being adjudicated and how it is being decided. If VA’s decision notice doesn’t mention a claim, that claim was not adjudicated. Period.
This ruling applies to every VA decision notice issued on or after February 19, 2019, the AMA’s effective date. It does not reach back to legacy claims decided under the old system.
How This Ruling Affects TDIU Claims and Effective Dates
This is where Hamill becomes transformative for TDIU claimants. To understand why, you need to know how TDIU claims arise.
Under Rice v. Shinseki, 22 Vet. App. 447 (2009), TDIU is not a separate, standalone claim. It is part of any claim for VA disability compensation when the evidence reasonably raises the issue of unemployability. If a veteran files for an increased rating and the C&P examiner notes that the veteran’s PTSD prevents them from holding a job, TDIU has been raised by the record whether or not the veteran submitted a VA Form 21-8940.
Here’s the problem. VA routinely ignores evidence of unemployability. A veteran files for an increased rating. The examiner notes the veteran can’t work. VA rates the condition at 70% and says nothing about TDIU. Under the old implicit denial doctrine, VA could argue that the denial of a higher schedular rating implicitly denied TDIU as well. The veteran’s TDIU claim would be considered adjudicated, the appeal window would start running, and the veteran would lose the ability to secure an earlier effective date.
Hamill changes that equation for AMA-era claims. If VA issued a decision that addressed your rating but never mentioned TDIU never identified it as an issue, never explained why it was denied then under Hamill, your TDIU claim was not adjudicated. It remained pending.
A pending claim preserves its effective date. If TDIU was reasonably raised by your record in 2019, and VA never explicitly decided it, that claim has been sitting unadjudicated for years. When TDIU is eventually granted, the effective date can potentially reach all the way back to when the claim was first raised, not the date you finally got VA to address it.
The math on this can be substantial. TDIU pays at the 100% rate, which is currently over $3,900 per month for a single veteran with no dependents. If your effective date moves back several years because VA failed to explicitly decide a pending TDIU claim, the retroactive compensation can easily reach into the tens or hundreds of thousands of dollars.
What Veterans Should Do Now
If you’ve received VA decision notices since February 19, 2019, pull them out and review them carefully. Look at the issues VA listed as adjudicated. If you had evidence in your file suggesting you were unable to work due to service-connected conditions statements to examiners about leaving a job, C&P exam findings about occupational impairment, lay statements about your inability to maintain employment, and VA never expressly addressed TDIU, that claim may still be pending under Hamill.
This applies broadly, not just to TDIU. Any claim you filed that VA failed to explicitly address in its decision notice may be unadjudicated under this ruling. But TDIU is the area where the impact is likely to be largest, because TDIU claims are frequently raised by the evidence rather than by formal application and VA has a well-documented pattern of ignoring them.
Do not assume VA addressed everything. Look at what the decision notice actually says. If a claim isn’t listed, it may still be alive.
Why You Need an Attorney to Maximize Your TDIU Effective Date
Identifying an implicit TDIU claim in a veteran’s record requires more than reading one or two decision letters. It requires a page-by-page review of the entire claims file every C&P exam, every treatment note, every statement in support of claim, every VA form going back years, sometimes decades. The question is whether, at some earlier point in time, the evidence reasonably raised the issue of unemployability. That’s a fact-intensive inquiry, and it’s exactly the kind of analysis that gets overlooked by veterans handling the process on their own.
At After Service, this is a core part of how we handle TDIU cases. We review every page of the claims file looking for evidence that TDIU was reasonably raised. We identify the earliest possible date, build the evidentiary record to support that date including obtaining expert vocational opinions when needed and make the legal arguments to secure the maximum retroactive compensation the veteran is owed.
Hamill v. Collins makes this work even more valuable. Under the old system, an implicit denial might have cut off an earlier effective date even if we found evidence of unemployability years back. Under the AMA, if VA never explicitly decided the TDIU issue, that claim remained pending and the effective date may reach all the way back.
If you’ve been granted TDIU but believe your effective date should be earlier, or if VA has rated your conditions without ever addressing TDIU despite evidence that you can’t work, contact After Service LLC for a free consultation. We represent veterans nationwide and can evaluate whether Hamill applies to your case and whether you may be entitled to an earlier effective date with significant retroactive pay.
