A VA disability rating is not carved in stone. Hundreds of thousands of veterans receive ratings that are too low — either because their conditions have worsened, because related conditions were never claimed, or because VA made errors in the original decision. This guide walks through seven CFR-backed strategies that can legally and legitimately increase your rating and your monthly compensation. Each strategy includes the specific regulation, the right form to file, a realistic timeline, and the dollar impact based on 2025 pay rates.
Before diving into the strategies, here is what a rating increase actually means in dollars. These are the 2025 monthly compensation rates for a veteran with no dependents:
| Combined Rating | Monthly Payment (No Dependents) | Annual Payment |
|---|---|---|
| 10% | $175.51 | $2,106 |
| 20% | $346.95 | $4,163 |
| 30% | $537.42 | $6,449 |
| 40% | $774.16 | $9,290 |
| 50% | $1,102.04 | $13,224 |
| 60% | $1,395.93 | $16,751 |
| 70% | $1,716.28 | $20,595 |
| 80% | $1,995.01 | $23,940 |
| 90% | $2,241.91 | $26,903 |
| 100% | $3,737.85 | $44,854 |
| TDIU (100% rate) | $3,737.85 | $44,854 |
The jump from 60% to 70% is worth $320 per month — $3,840 per year. The jump to 100% or TDIU is the largest single increase in the VA system. Use our VA rating estimator to model what your combined rating would be after adding conditions.
If a service-connected condition has gotten worse since your last rating decision, you have the right to file a claim for increase. VA is required by law to assign a higher rating if your current symptoms meet the criteria for a higher evaluation under the applicable diagnostic code.
Under 38 CFR 3.105(e), VA must reduce a rating only with due process protections — and the same framework requires an increase when evidence of worsening is presented. When you file a claim for increase, VA schedules a Compensation and Pension (C&P) examination to evaluate your current severity.
This is critical to understand: your effective date for a claim for increase is generally the date VA receives your claim. However, under 38 CFR 3.400(o)(2), if the evidence shows your condition was at the higher severity level for up to one year before you filed, VA must assign an effective date going back to the earliest point within that one-year period when the worsening was present. This means medical records from your private doctor in the year before you file can dramatically increase your retroactive pay.
VA's average processing time for claims for increase in 2025 is 103–145 days. After the C&P exam, you typically receive a rating decision within 30–60 days.
A veteran rated 40% for knee limitation of motion whose symptoms now meet 60% criteria would increase from $774/mo to $1,396/mo — a gain of $622 per month, plus back pay to the date of claim or earlier if evidence supports it.
One of the most powerful and underused strategies is secondary service connection. Under 38 CFR 3.310, a condition caused or aggravated by an already service-connected disability is itself service-connected — and rated separately. Secondary conditions stack on top of your existing rating through VA's combined ratings formula.
Secondary service connection requires a nexus letter — a medical opinion stating that the secondary condition is "at least as likely as not" caused or aggravated by the service-connected primary condition. The letter must be from a licensed medical provider and address the medical relationship specifically. Use VA Form 21-526EZ to file, attaching the nexus letter and all supporting records.
Under 38 CFR 3.310(b), a secondary condition does not have to be caused by the service-connected condition — it just needs to be aggravated beyond its natural progression. This is a lower bar, and many veterans miss benefits because they do not realize their pre-existing conditions can qualify.
Secondary claims are processed like any new claim — generally 103–145 days. Each successfully connected secondary condition adds to your combined rating. A veteran at 50% who adds bilateral radiculopathy (10% each leg) moves to approximately 64% combined, which rounds to 60% — and then to 70% combined with an additional 10% condition.
Many veterans have conditions that were treated during service — documented in their service treatment records — but were never formally claimed. These conditions can still be service-connected years or decades later using the doctrine of continuity of symptomatology.
Under 38 CFR 3.303(b), for certain chronic diseases listed in 38 CFR 3.309 (including arthritis, hypertension, diabetes, and several others), if the condition was shown in service and has continued since separation, service connection is warranted even without a direct nexus opinion. For non-listed conditions, continuity of symptomatology requires showing symptoms from service to the present, even if not continuously documented.
File a new claim on VA Form 21-526EZ, listing each unrated condition separately. Attach service treatment records showing in-service treatment, and a nexus letter or statement linking service to current diagnosis. For chronic diseases under 38 CFR 3.309, the records themselves may be sufficient without a separate nexus opinion.
A Vietnam veteran treated for back pain and hypertension during service, but who only filed for PTSD at separation, can file new claims for both. If both are granted, his combined rating increases from 70% to potentially 85–90%, adding $500–$525 per month.
Total Disability Individual Unemployability (TDIU) allows veterans to receive compensation at the 100% rate ($3,737.85/mo in 2025) even if their combined rating is below 100%. This is one of the most significant benefit increases available in the VA system.
Under 38 CFR 4.16, a veteran qualifies for TDIU if:
TDIU requires showing that service-connected disabilities prevent you from securing and following "substantially gainful employment" — meaning competitive employment paying above the federal poverty level. Marginal employment (below poverty line) does not disqualify you. Sheltered employment (supervised workshops, heavily accommodated settings) does not disqualify you either.
File VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Unemployability). You will need:
TDIU claims take 4–6 months on average. If VA denies TDIU but you believe you qualify, an appeal is strongly warranted — use our denial analyzer to evaluate the grounds for appeal.
Veterans often do not realize they can proactively request a new C&P examination when their service-connected condition worsens significantly. This is especially valuable when a condition previously rated at a moderate level has progressed to severe.
Under 38 CFR 3.327, VA may schedule periodic re-examinations when it is warranted by the nature of the disability, the need for a current evaluation, or changes in law. Veterans can request a re-examination by submitting a claim for increase, supported by current medical evidence showing the progression.
File a claim for increase on VA Form 21-526EZ with current medical records. A letter from your treating physician describing the worsening and requesting re-evaluation carries significant weight. Avoid going to a C&P exam without documentation — the examiner relies heavily on your current medical records.
When you request re-examination, VA may find your condition has improved as well as worsened. Before requesting a reexam, ensure you have current medical records that clearly document the deterioration. Do not request reexam on a stable condition if you cannot prove worsening.
A rating decision that seems too low often is too low. VA examiners make errors — wrong diagnostic codes, inadequate C&P exams, failure to apply favorable rules. Understanding the specific error is the first step to a successful appeal.
VA rates each condition under a specific diagnostic code in 38 CFR Part 4. If the examiner used the wrong code — for example, rating a knee condition under a less favorable code that ignores instability — the rating may be significantly undervalued. Pull your rating decision and compare the assigned diagnostic code to the full schedule in 38 CFR Part 4.
Under 38 CFR 4.2, VA must ensure the examination is thorough enough to rate the disability. If the examiner spent only minutes with you, did not test range of motion under repetition, or failed to document findings that match your symptoms, the exam is legally inadequate and can be challenged. A report that is "not adequate for rating purposes" is grounds for a new exam.
Under 38 CFR 4.59, where painful motion is the basis of the disability, VA must assign a rating even when range of motion measurements technically fall in a lower bracket, because pain limits functional motion. This rule is systematically under-applied. If your C&P exam measured your range of motion but the examiner did not document pain on motion or functional limitation, cite 38 CFR 4.59 in your appeal.
Use our denial analyzer to identify the specific error in your decision and the best appeal lane for your situation.
A Clear and Unmistakable Error (CUE) claim is unlike any other VA motion. It has no time limit — you can challenge a decision from 1975 or 1985 — and if granted, VA must pay you as if the correct decision had been made on the original date. For veterans whose ratings were significantly undervalued decades ago, a successful CUE claim can result in six figures of back pay.
CUE is a high legal standard. Under the regulatory framework established in Russell v. Principi and Fugo v. Brown, a CUE exists when:
CUE is not a second chance to disagree with a judgment call — it must be a clear legal or factual error, not a mere difference of opinion about how evidence was weighed.
CUE motions are filed with the agency of original jurisdiction (the VA Regional Office that issued the decision) or with the Board of Veterans' Appeals for a BVA decision. There is no specific form — file a detailed written motion citing:
CUE motions are among the most legally demanding VA filings. The standard is strict and most pro se CUE motions fail on procedural grounds. An accredited VA attorney who works on contingency can evaluate whether a CUE exists without any upfront cost to you.
These seven strategies are not mutually exclusive — many veterans pursue two or three simultaneously. A typical increase path might look like this:
