What if the reason your claim keeps getting denied isn't that you aren't hurting, but that you're using a causation logic that became obsolete on May 1, 2026?
For years, the VA has leaned on a strict "direct proximate cause" standard to shut down secondary claims. If your service-connected PTSD didn't directly create your sleep apnea from thin air, the rater’s stamp hit the desk with a "denied." But a massive shift in the 38 CFR updates and a landmark case implementation has changed the battlefield. If you aren’t using the new "But-For" standard, you are leaving your rating to chance.
At GVC4Vets, we’ve seen over 100,000 veterans fight this system. The "secret" isn't a magic trick, it’s the tactical application of the law.
Key Takeaways
- The Spicer Shift: The VA must now apply the "But-For" standard, meaning if your condition wouldn't be this severe but for your service-connected disability, it qualifies.
- Aggravation is Evidence: You no longer need to prove your primary disability caused the secondary one; you only need to prove it made it worse or interfered with treatment.
- 38 CFR § 3.310 TBI Update: New presumptive secondary links for TBI (including Depression and Parkinsonism) are now officially on the books as of 2026.
- Objective Over Subjective: Stop telling the rater it "hurts" and start using the language of the rater to bridge the medical gap.

1. The 2026 'But-For' Revolution: Spicer v. McDonough
For decades, the VA Adjudication Manual (M21-1) was a wall. Raters were trained to look for a straight line. If you claimed GERD secondary to your NSAID intake for service-connected knee pain, they often looked for a reason to say the link was too weak.
That wall crumbled with the implementation of the Federal Circuit’s decision in Spicer v. McDonough. As of May 2026, the VA is legally required to ask a broader question: "Would this condition be less severe today, or not have occurred, but for the service-connected disability?"
This is a tactical gift for veterans. It shifts the burden of proof from "Direct Causation" to "Secondary Aggravation." Under the new VA secrets of adjudication, your nexus doesn't have to be a single event; it can be a chain of events. If your service-connected back pain (Diagnostic Code 5243) prevents you from exercising, leading to weight gain, which then leads to hypertension, the hypertension is now a "But-For" secondary condition.
2. Decoding the 38 CFR § 3.310 Amendments
The VA doesn't just change rules for fun; they change them because of legal pressure. The January 22, 2026, amendment to 38 CFR § 3.310 specifically targeted veterans with Traumatic Brain Injury (TBI).
If you have a service-connected moderate or severe TBI, the following are now presumed secondary:
- Parkinsonism or Parkinson’s Disease
- Unprovoked Seizures
- Dementias (if manifested within 15 years)
- Depression (if manifested within 3 years of a moderate/severe TBI or 12 months of a mild TBI)
The outrage here is that many veterans are still filing these as "direct" claims and getting denied because they can't find an in-service event for their depression ten years after discharge. GVC4Vets urges you: Stop fighting the uphill battle of direct service connection when the law now gives you the secondary presumption.
3. The Strategy: Bridging the Medical Gap
A successful VA disability increase through secondary claims requires you to stop being a patient and start being a strategist. You must provide your doctor with the "language of the rater."
When you sit down for an evaluation, your medical documentation must be objective.
- Don't say: "My back makes my legs hurt."
- Do say: "The lumbar strain (38 CFR § 4.71a) results in radiculopathy of the sciatic nerve, evidenced by a positive straight-leg raise and decreased sensation in the L5 dermatome."
The rater isn't a doctor; they are a bureaucrat looking for checkboxes. If your nexus letter doesn't explicitly use the phrase "at least as likely as not" and reference the "but-for" standard, it is dead on arrival.
4. Pes Planus vs. Plantar Fasciitis: A Secondary Logic Study
One of the most common points of confusion is the difference between these two foot conditions and how they interact in a secondary claim.
| Feature | Pes Planus (Flat Feet) | Plantar Fasciitis |
|---|---|---|
| Pathology | Structural collapse of the medial longitudinal arch. | Inflammation of the thick band of tissue (fascia) on the bottom of the foot. |
| Objective Data | Calcaneal eversion, "pronation," or "flatness" documented by weight-bearing X-rays. | Point tenderness at the calcaneal attachment; pain most severe during the first steps of the morning. |
| VA Rating Rule | Rated under DC 5276 (0% to 50%). | Rated under DC 5269 (10% to 30%). |
| Secondary Logic | Often the primary cause of secondary knee or hip issues due to altered gait. | Often the secondary result of an altered gait from a service-connected knee or hip injury. |
The "But-For" secret here is Gait Analysis. If you have a service-connected knee injury, your "antalgic gait" (limping) is putting abnormal stress on your fascia. You aren't claiming Plantar Fasciitis happened in the Army; you are claiming it happened but for the way you've had to walk for the last ten years because of your service-connected knee.
5. The 'Treatment Interference' Secret
This is the most powerful weapon in the 2026 arsenal that most "experts" ignore. Under the new M21-1 updates, a condition can be secondary if the primary condition interfered with its treatment.
Example: You have a non-service-connected heart condition. You also have service-connected severe PTSD. If your PTSD symptoms (anxiety, agoraphobia) prevent you from attending cardiac rehab or taking necessary heart medications, the worsening of your heart condition is now a secondary service connection.
You must document:
- The recommended treatment for the non-service-connected condition.
- Specific instances where your service-connected disability prevented that treatment.
- The medical outcome (worsening) of that missed treatment.
6. Veteran Action Checklist: Mission Prep
Before you hit "submit" on your next claim, verify these four tactical points:
- Confirm "But-For" Language: Does your medical nexus state that the secondary condition would be less severe but for the primary condition?
- Verify Diagnostic Codes: Are you using the correct codes (e.g., Diagnostic Code 6522 for Sleep Apnea or 38 CFR § 4.97 for respiratory) to ensure the rater knows exactly where to look?
- Identify Treatment Interference: Have you documented how your service-connected pain or mental health has "impeded" your recovery for other issues?
- Bridge the Gap with Data: Ensure your DBQs contain objective measurements (Range of Motion, X-ray findings, Lab results) rather than just "subjective" reports of pain.
FAQ: Critical Intelligence for 2026 Claims
Q: Did the VA eliminate secondary claims in 2026?
A: No. In fact, they expanded them. While some rumors suggested "tightening," the implementation of Spicer v. McDonough actually makes it easier to link conditions through "aggravation" and "treatment interference."
Q: What is the "at least as likely as not" standard?
A: This is the legal threshold for VA claims. It means there is at least a 50% probability that your condition is linked to service. The "But-For" standard fits within this, proving that the secondary condition’s current severity is 50% or more likely due to the primary disability.
Q: Can I claim a secondary condition if I'm already at 100%?
A: Yes. This is often done for Special Monthly Compensation (SMC) or to ensure that survivors are eligible for DIC (Dependency and Indemnity Compensation) if the veteran passes away from a service-connected cause.
Q: How many doctors does GVC4Vets work with to help with these claims?
A: GVC4Vets connects veterans with a network of over 800 independent, licensed physicians who understand the specific requirements of VA-compliant medical documentation and the "But-For" standard.
Q: What if my C&P examiner ignores the new 2026 rules?
A: This is common. If a C&P examiner uses the old "direct cause" logic, you must challenge the exam. Use your own Independent Medical Evaluation (IME) that cites the Spicer decision and the updated M21-1 manual to force a Higher-Level Review (HLR).
