How to File for a VA Rating Increase — and the Honest Math on Whether It's Worth It

Conditions don't sign a contract to stay the way they were rated. The knee that was 10% at separation is a different knee fifteen years later; the mental health rating from a decade ago may not describe this year at all. The VA has a process for exactly this — the claim for increase — and it's straightforward, as long as you go in knowing the evidence rules, the honest risks, and one piece of math most veterans skip.

When an increase claim makes sense

One condition: your service-connected condition has genuinely worsened, and the record can show it. That second half is the whole game. "It's worse" is a sentence; treatment notes documenting more frequent flare-ups, escalating medication, new functional limits, or a changed diagnosis picture are evidence. If the worsening is real but undocumented, the first move isn't filing — it's getting current treatment on the record.

How to file one

1. Intent to File first — same as any claim, it locks your date for up to a year while you build the evidence.
2. Gather the current picture. Recent treatment records are the backbone. A private DBQ measuring the current severity against the rating criteria is one of the strongest additions for an increase — this is precisely the scenario it's built for. A short personal statement documenting what's changed (frequency, severity, what you can no longer do) rounds it out. No new nexus letter needed — the condition is already service-connected; only severity is in question.
3. File VA Form 21-526EZ — the same form as an original claim, with the condition marked as a claim for increase.
4. Attend the new C&P exam. The VA will almost certainly schedule one to measure current severity. Everything in what not to say at a C&P exam applies double, because this exam exists specifically to answer "how bad is it now?"

The effective-date bonus most veterans miss

Increase claims have their own dating rule, and it can work backward in your favor: the effective date is when the VA received your claim or the date the evidence shows the worsening occurred — up to one year before you filed — whichever is earlier. A treatment note from ten months ago documenting the deterioration isn't just support for the higher percentage; it can be ten months of back pay. Date-stamped evidence pays twice.

The honest risk section

Filing an increase puts the condition — and technically the file — in front of a rater again. Three truths, in proportion:

• Reduction is possible but bounded. The VA can't reduce a rating on a whim; it generally needs evidence of sustained material improvement, not one good exam day. If your condition genuinely worsened, the risk is low.
• Time builds armor. Ratings held five years or more can only be reduced on a showing of sustained improvement under the ordinary conditions of life; at ten years the service connection itself is protected; at twenty the percentage has a permanent floor. The protected-ratings guide walks all three rules.
• The real red flag is silence. The scenario that actually produces reductions isn't filing for an increase — it's a file showing no treatment for years, suggesting the condition resolved. Current, ongoing treatment records are both your increase evidence and your protection.

The math check to run before you file

Here's the part the law-firm guides skip: because VA math combines rather than adds, an increase on one condition often moves your combined rating less than you'd expect — each rating only takes a slice of what's left of the whole person, and the higher your combined number, the thinner the slices. A 30%→50% jump might move your combined rating a full tier, or not at all, depending entirely on where your pre-rounding total sits.

So before you spend months on an increase, run both scenarios in the VA Math Calculator: your ratings with the increase, and your ratings with a plausible new claim instead — veterans in the 70–90% range are often surprised which one moves the check more. A documented secondary condition is a fresh bite of the remainder; an increase is a bigger bite of a slice already counted. Sometimes the increase wins. Know before you file.

Bottom line

If your condition is worse and the record shows it, the increase claim is a normal, low-drama process: ITF, current evidence, the same form, a new exam, honest answers. Keep treatment current (that's evidence and armor at once), mine your records for the earliest date the worsening shows, and run the combined-rating math first so you're fighting the battle that actually raises the check.
