Intent-to-File, Secondaries, and Presumptives
An Intent to File freezes your effective date in place for a year while you build the rest of the claim. One page. Costs nothing. The month you skip it is the month the clock starts running against you instead of for you.
Run the math. One month of compensation for a 70% rated veteran with a spouse comes to roughly $1,900 in 2026. Miss a full year of back pay because no ITF was on file when you started, and that's twenty-three grand you will never see again. Gone behind a form you could have submitted in four minutes.
Then come the secondaries, where the VA has already done half your work for you and almost nobody collects. And the presumptives, where Congress signed off on your nexus before you walked in the door. Last lesson you built the Condition Strategy Map. This one loads the two categories at the bottom of it and bolts down the dates on all of it.
The ITF: a one-page form that pays
An Intent to File tells the VA you mean to file a disability claim within the next year. Once it's logged, it holds your effective date for up to twelve months while you gather evidence and build the actual claim.
Why that matters: when your claim gets granted, your compensation backdates to the effective date, not to the day the VA stamped the grant. For a new condition, the effective date is the day you filed the claim. Unless you have a live ITF and file the real claim inside a year, in which case it's the day you submitted the ITF.
That gap is months of back pay. Sometimes a year of it. The grant can crawl eight months, ten, fourteen, and every one of those months pays out retroactive to the date you locked with the ITF.
File the ITF first, before anything else
The minute you decide you might pursue a claim, file the ITF. Before the evidence. Before the statements. Before you've finished mapping your conditions. The form holds up to twelve months of back pay and costs nothing to send.
Online is fastest. Log in at VA.gov with your ID.me or Login.gov credentials, search "Intent to File," pick disability compensation as the benefit type, submit. A confirmation number lands on the spot. Save it. Screenshot it. The ITF runs twelve months from that submission date.
The paper fallback is VA Form 21-0966. Download it, fill it out, mail it or hand it to a VSO. The online route is faster and spits back an immediate confirmation, so take it unless something forces the paper.
To cash in that protected date, you have to submit a complete claim on VA Form 21-526EZ or through the VA.gov online tool within twelve months of the ITF date. Do that, and anything granted backdates to the ITF date. Let the twelve months bleed out, the ITF lapses. You can file a fresh one any day.
Some vets keep one running without a break. File the ITF, file a claim around month eleven, then file a new ITF the same afternoon to crack open a fresh twelve-month window for the next round. That keeps effective-date protection breathing across multiple claim cycles, which is what you want when you're filing in batches.
What the ITF does not do
The ITF only shields new claims you file inside its window. It does nothing for claims already filed. If you submitted a claim six months ago with no ITF in place, that claim's effective date is the day you filed it. No earlier date existed to protect, so nothing backdates.
That's the whole reason the ITF leads any claim cycle. File it, build the evidence, submit the claim. That order, every time. Your system prompt already tells the analyst to ask about ITF status early in any filing discussion. If your answer is "I don't have one," then before another keystroke, you go file it.
Secondaries: the highest-leverage play on the board
A secondary condition is a disability caused or aggravated by a condition you're already service-connected for. Under 38 CFR 3.310, if condition B was caused or worsened by your service-connected condition A, then B rides in service-connected too.
Read what that skips. No deployment records. No in-service event. No presumptive list. The nexus you owe is between two conditions, not between a condition and your time in uniform. The thread back to service is already tied off, because the primary is already granted.
That's why secondaries are the highest-leverage claims on the board. Service connection sits half-finished before you start. And almost nobody touches them. Most vets never file a single one. The ones who do file the obvious pair, radiculopathy off the back, tinnitus off the hearing loss, and walk past the rest of the map. The map is where the money lives.
The magic phrase and the high-value map
The standard you're proving is "at least as likely as not," meaning 50 percent probability or greater. That exact phrase is the bar the VA measures against. A nexus letter that says "possibly" or "could be" reads soft and hands the rater an excuse to drop it below the line. If your doctor writes the letter, the words "at least as likely as not" go in it.
What follows is a pattern library, not a ruling on your eligibility. These are the connections the analyst goes hunting for in your records.
Off a musculoskeletal primary, the back or knee or hip or shoulder or neck: radiculopathy, altered-gait stress that chews up the other joints, depression or anxiety bred by chronic pain, sleep disturbance, opioid dependency if they prescribed for the pain, ED off the pain meds.
Off a mental health primary, PTSD or depression or anxiety: sleep apnea, hypertension, GERD, migraines, IBS, ED, substance use, the bruxism that wears your teeth flat and the TMJ behind it.
Off diabetes type 2: peripheral neuropathy, retinopathy, coronary artery disease, kidney dysfunction, ED. Off sleep apnea: hypertension, cardiovascular disease, depression, cognitive fog. Off TBI: migraines, tinnitus, cognitive impairment, mental health conditions, sleep disorders, the endocrine system gone sideways.
The one most vets leave lying on the table is sleep apnea secondary to mental health. High-value, badly underfiled. Sleep apnea rated at 50% requires CPAP use, and 50% is the common landing spot for the vets who need the machine. 100% requires documented chronic respiratory failure. If you're service-connected for PTSD, anxiety, or depression and you carry a sleep apnea diagnosis, even years downstream, that claim walks on real legs.
Feed the analyst your service-connected conditions and tell it to map every plausible secondary with the nexus logic, the likely rating range, and the evidence each one needs. It runs your records against these patterns and hands you a list. Then you verify. It drafts a nexus template and a personal statement, but a brilliant intern with a reading addiction still hands you wrong things, so you check every claim against the actual conditions in your file before a page of it goes in.
Presumptives: the closest thing to free money
Presumptive service connection needs no nexus letter at all. Meet the service criteria, carry a diagnosis of a listed condition, file, get granted. The presumption does the nexus work for you, because Congress decided that proving causation one veteran at a time was unreasonable for certain cohorts. This is where you open a claim portfolio.
The PACT Act, the Honoring Our Promise to Address Comprehensive Toxics Act of 2022, is the biggest expansion of VA presumptives in a generation. The burn-pit provisions cover service in Iraq, Afghanistan, Kuwait, Saudi Arabia, Qatar, UAE, Bahrain, Oman, Jordan, Egypt, Syria, Yemen, Djibouti, or Uzbekistan during the Gulf War or post-9/11 periods. There's also Agent Orange for Vietnam-era vets, Gulf War Illness for Southwest Asia theater service, and radiation exposure for atomic vets and certain nuclear cohorts.
Camp Lejeune is its own door. Stationed at Camp Lejeune or MCAS New River between August 1953 and December 1987 for at least 30 days, and you carry presumptive coverage for conditions including kidney cancer, liver cancer, non-Hodgkin lymphoma, adult leukemia, multiple myeloma, Parkinson's, and aplastic anemia.
Screen yourself with one prompt: based on your service dates, locations, and cohort, have the analyst audit every presumptive list you might qualify for, then flag any conditions already sitting diagnosed in your records. The lists shift and the analyst can lag a step behind them, so confirm every match against the current list on VA.gov before you file. Presumptives move faster than contested direct claims and carry significantly higher grant rates in the VA's own data, so they go first in your filing order.
The front and back of your effective dates are nailed down now, and the two easiest categories on the map sit loaded. Mark this one done. Next we walk into the exam room. The C&P. The single highest-leverage hour of your whole claim, and the day you stop letting it happen to you.
