The VA rates asthma under 38 CFR § 4.97, Diagnostic Code 6602, at 10%, 30%, 60%, or 100%. Every tier is written with the word "or," which means you only need to meet one criterion at each level, not all of them. That is why your prescription bottle often matters more than your spirometry printout. Daily use of an inhaled anti-inflammatory medication like Symbicort, Advair, or Flovent meets the 30% criteria on its own, even when your breathing test comes back normal. Documented prednisone bursts at least three times a year meet the 60% criteria the same way.

There is no statute of limitations on a 38 U.S.C. § 1151 claim. You can file at any time, even decades after the VA treatment that harmed you. Two other clocks still control how much you are paid and which legal options you keep. Most articles on this topic never mention them. This guide explains how the three timelines work together and why waiting costs money even when it does not cost the claim.

MST markers are the indirect evidence the VA accepts to support a military sexual trauma claim when the event was never officially reported: records from the time, changes in a veteran's service record, and statements from people who knew. Under 38 CFR § 3.304(f)(5), a qualified clinician's written interpretation of the markers can help corroborate that the event occurred. The pattern, explained well, is the evidence.

In February 2026 the VA published a rule that would have rated your disability based on how you function on your medication, then rescinded it days later. The prior standard is back. And here's what trips up most veterans: Ingram v. Collins was never rescinded, only the rule that tried to override it was. That's why your C&P exam still asks about your functioning without medication. This is where things actually stand, and what the evidence needs to show to capture your true severity.

The VA has proposed changing how it rates sleep apnea, and the change would end the automatic 50% rating that veterans now get for using a CPAP. The proposal is not final, there is no start date, and current ratings would be protected. But if you have sleep apnea and are not yet service-connected, this is a “file while the current rules are in effect” moment. Here is what would change, what is still the same, and what to do now.

A C&P examiner who writes "less likely than not" is saying the odds your condition is service-connected are below 50 percent, which usually means a denial. But it is one opinion, not a verdict. Because the VA grants a claim when the evidence is at least evenly balanced (the benefit-of-the-doubt rule), you do not have to prove your case beyond doubt. You only have to bring it to a tie. This guide explains what the phrase means, the five most common flaws in a negative C&P opinion, and how a well-reasoned rebuttal opinion answers it, with the case law that makes it work.

After Spicer v. McDonough, your service-connected condition does not have to cause another condition for you to connect it. If your service-connected condition, or the medicine that treats it, blocked or delayed the treatment of another condition, that may be enough. This is one of the most useful changes in VA law in years, and almost no one explains it in plain English. Here is what it means and how it works.

Garner v. Tran (2021) is the case that defines which "first-links" actually count when obesity stands between a service-connected condition and a new disability. The Court laid out a six-factor, non-exhaustive list of the evidence that can raise the theory—from mobility loss and medication side effects to clinician statements. Because the list is non-exhaustive, the door isn't shut: if your record draws a reasonable association between your weight gain and your service-connected condition, the VA has to consider it. Here's the six-factor test, the three-part Walsh causation standard, and what a defensible nexus letter must show.

PTSD can both cause and worsen migraines, and the VA can grant migraines as secondary to a service-connected PTSD rating. You'll need a current migraine diagnosis, your PTSD rating, and a medical opinion explaining the link — usually the HPA-axis stress pathway. Migraines are rated 0–50% under 38 CFR § 4.124a, DC 8100, based on how often you get prostrating attacks.

The VA frequently denies tinnitus even after conceding both the diagnosis and in-service noise exposure — denying only on the nexus, the medical link. The most common reason given is that the veteran's audiogram is normal, so the noise supposedly caused no injury. That reasoning is contradicted by the science of "hidden hearing loss" (cochlear synaptopathy): loud noise can permanently damage the inner ear's nerve connections while the standard hearing test stays normal. A focused independent medical opinion that explains this mechanism — and addresses what the exam missed — is built to close exactly that gap.

A VA Intent to File (VA Form 21-0966) tells the VA you plan to file a claim and preserves your effective date for up to one year while you gather evidence. You can file it three ways — online at VA.gov, by phone at 1-800-827-1000, or by mailing the paper form. File your complete claim within that year and the VA pays back pay to your Intent to File date. Miss the deadline, and the clock resets.

The difference between being unemployed and being unemployable decides more TDIU claims than any other single factor — and most veterans don’t know it exists. The VA isn’t asking whether you have a job. It’s asking whether you’re capable of doing one.

TDIU pays at the 100% rate when your service-connected conditions stop you from working — but the VA decides it on an occupational question most claims never prove. Here is the evidence that actually wins it

The baseline requirement for secondary aggravation claims came from 38 C.F.R. § 3.310(b). The Federal Circuit struck down that regulation in Spicer v. McDonough. The statute (38 U.S.C. § 1110) says nothing about baselines. But as of May 2026, VA has not formally rewritten the regulation, and C&P exam templates still ask examiners to address baseline. Here's the key: the exam templates themselves say the aggravation question must be answered "regardless of an established baseline." The baseline is a rating tool, not a gatekeeping tool. When it can't be determined, §§ 3.22 and 4.22 mean no deduction — the veteran gets the full current rating.

A strong secondary nexus letter after Spicer v. McDonough includes seven sections: provider qualifications, records reviewed, veteran-specific timeline, diagnosis, a nexus opinion addressing all three pathways (causation, aggravation, treatment interference), medical rationale with peer-reviewed citations, and proper signature. The five most common reasons nexus letters get denied are: no mechanism explained, template language, ignoring aggravation, wrong probability language, and failing to address the C&P examiner's negative opinion.

The Federal Circuit struck down the old proximate-cause standard. The VA updated its adjudication manual. Here's what changed, what stayed the same, and how your nexus letter needs to adapt — explained by clinicians, not attorneys.

Veterans are using ChatGPT and AI tools to generate nexus letters for VA disability claims. The advice is everywhere on Reddit and YouTube. But AI-generated letters fail the VA's competent medical evidence standard — and the VA's 2026 fraud-detection tool was built to catch exactly what these tools produce.

Filing for Aid and Attendance (SMC-L) does not automatically trigger a review or reduction of your existing service-connected ratings. However, the VA may order a new Compensation and Pension (C&P) examination as part of processing the SMC claim, and the results of that examination could theoretically lead to a proposed reduction if the examiner documents improvement in a previously rated condition. Veterans with Permanent and Total (P&T) status, ratings protected under the 5-year, 10-year, or 20-year stabilization rules (38 CFR § 3.344, 38 CFR § 3.951), or ratings that are static by nature face minimal practical risk. Understanding the protections already in your file — and how to document the SMC claim correctly — is the key to filing confidently.

A 38 U.S.C. § 1151 claim is a VA disability benefits claim that compensates veterans who suffered additional disability caused by VA hospital care, medical treatment, surgical treatment, or examination. Unlike standard service connection, it does not require a link to military service. The veteran must prove VA care caused the injury and that VA was at fault or the outcome was not reasonably foreseeable. If granted, benefits are paid as if the disability were service-connected.

The VA denies hearing loss claims when audiometric test results do not meet the requirements under 38 CFR §3.385. Even if hearing loss is real and service-related, the VA requires specific thresholds or Maryland CNC scores below 94% to approve the claim.

Not every claim needs a nexus letter. Not every claim needs a private DBQ. We'll tell you that honestly — because the goal is to help you file a claim that's ready, not to sell you services you don't need. That's the foundation of every Claim Readiness Review we conduct.

A nexus letter can be the single document that turns a VA denial into a monthly benefit for life. But most letters submitted to the VA are too weak to do the job. Here is what the evidence actually needs to show - and why - from the clinicians who write them.

A complete 2026 guide to Aid and Attendance vs. Housebound benefits, covering eligibility requirements, ADLs, SMC vs. pension pathways, monthly payment rates, and VA Form 21-2680 documentation. Includes common denial reasons and how to strengthen your claim.

Permanent and Total (P&T) means the VA has determined your service-connected disabilities are rated at 100% and are not expected to improve. P&T is not just a rating — it's a gateway to additional benefits including CHAMPVA for dependents, Chapter 35 education benefits, property tax exemptions, and eligibility for Aid and Attendance (SMC-L) and higher levels of Special Monthly Compensation. Many P&T veterans are undercompensated because they don't know about the benefits P&T unlocks or don't realize their conditions have progressed to the point of qualifying for SMC.

The VA gives the most probative weight to nexus letters written by board-certified specialists whose specialty matches the claimed condition. A psychiatrist for PTSD. A cardiologist for heart disease. An internal medicine MD for most routine claims like hypertension, diabetes, and GERD. A chiropractor only for musculoskeletal claims within their scope. Choosing the wrong specialty is the single most common reason well-documented nexus letters get assigned minimal weight and claims still get denied.

This guide explains how veterans can win a PTSD VA disability claim by meeting three requirements: a formal PTSD diagnosis, a documented in‑service stressor, and a clear medical nexus opinion using the “at least as likely as not” (≥50%) standard. It covers claim readiness, the top denial reasons, when and why to get a nexus letter/IMO, who should write it, and what makes it strong. The article also lists common secondary conditions (like sleep apnea, hypertension, depression, anxiety, IBS, migraines, GERD, cardiovascular disease, type 2 diabetes) that can increase overall VA disability ratings.

Crohn's disease can be service-connected as secondary to PTSD. The medical link between chronic PTSD and inflammatory bowel disease is well-documented in peer-reviewed research. But most of these claims get denied not because the connection isn't real, but because the nexus letter didn't prove it the way VA raters are required to accept. The fix is a properly structured medical opinion that covers causation, aggravation, and the specific gut-brain mechanisms linking PTSD to Crohn's.

Filing a VA disability claim on your own is entirely possible - and many veterans do it successfully. But "filing" and "filing correctly" are two very different things. A Claim Readiness Review exists to bridge that gap before it costs you time, money, or the benefits you've earned

If the VA denied your pre-existing condition claim, you may still qualify for service connection through aggravation beyond natural progression. Learn how to strengthen your case and rebuild your medical argument.

Obesity is not a VA-ratable disability, but it can serve as an intermediate cause for secondary conditions like Hypertension, Type 2 diabetes, Obstructive Sleep Apnea, and GERD.
