Three distinct federal protections govern when and how the VA can reduce your disability rating. The 5-year rule limits reductions on stabilized ratings. The 10-year rule protects service connection itself from being severed. The 20-year rule creates a permanent floor on combined ratings held long-term. Understanding these rules — and how to invoke them — can mean the difference between keeping your benefits and losing thousands of dollars per year.
For most veterans, their VA disability rating is their most important financial asset — producing monthly tax-free income that in many cases exceeds $30,000 per year. The VA retains the legal authority to reduce ratings when service-connected conditions improve. But this authority is not unlimited. Congress and the courts have established a tiered system of protections that grow stronger over time, making ratings harder to reduce the longer they have been in place.
The three primary protections are: the 5-year rule (requiring evidence of sustained material improvement for any reduction after five years); the 10-year rule (preventing the VA from severing service connection itself after a decade); and the 20-year rule (creating an unbreakable floor on a rating held for twenty or more years). Beyond these statutory and regulatory protections, veterans with Permanent and Total (P&T) designations receive additional safeguards against routine re-examination.
Veterans who receive a VA rating reduction notice — or who are scheduled for a re-examination that could lead to one — need to understand these protections before responding. Invoking the wrong rule, missing a deadline, or failing to submit the right evidence can result in a reduction that is otherwise preventable. This guide covers every protection in precise detail so you know exactly where you stand and what to do.
Rating held 5+ years cannot be reduced without clear evidence of sustained material improvement under ordinary conditions of life.
Service connection in place 10+ years cannot be severed — the underlying connection to military service is permanent (absent fraud).
Combined rating held 20+ years at a specific level cannot fall below that level. A permanent minimum floor is established.
VA has determined no improvement is expected — future C&P exams should not be scheduled. Strongest routine protection.
The 5-year rule is established under 38 CFR 3.951(b), which governs the "stabilization" of disability ratings. Under this regulation, a disability that has been continuously rated at a particular level for five or more years is considered a "stabilized" rating. For stabilized ratings, the VA is not permitted to reduce the rating unless it can demonstrate through a preponderance of the evidence that the veteran's condition has shown sustained material improvement under ordinary conditions of life.
The phrase "sustained material improvement under ordinary conditions of life" has specific legal meaning developed through decades of Board of Veterans' Appeals (BVA) and federal court decisions. "Sustained" means the improvement is not temporary or episodic — a good day or a good week does not qualify. "Material" means the improvement is significant enough to warrant a lower rating under the diagnostic criteria in the rating schedule. And "under ordinary conditions of life" means the improvement must be evident in the veteran's daily living and work environment, not just during a clinical examination at a VA facility.
In practice, the 5-year rule means that a single favorable C&P examination is generally not sufficient to reduce a stabilized rating. The VA examiner who finds improvement on a single examination has produced only one data point. If the veteran's treating physicians, employment records, family statements, and daily life activities all show continued significant limitation, the VA's own exam finding alone typically cannot clear the "sustained material improvement" bar.
When you receive a proposed rating reduction notice and your rating has been in place for five or more years, explicitly cite 38 CFR 3.951(b) in your response. State: "This rating was assigned on [date] and has been continuously in effect for [X] years, qualifying it as a stabilized rating under 38 CFR 3.951(b). The VA must demonstrate sustained material improvement under ordinary conditions of life — not improvement shown only on examination — before this rating may be reduced." Then provide evidence that no such sustained improvement has occurred: treating physician letters describing ongoing functional limitations, your own statement about daily difficulties, employer accommodations, activities you can no longer perform, and any hospitalizations or treatment changes showing progression rather than improvement.
The 5-year period is measured from the date the rating was first assigned, not from the date of the most recent rating decision. If you received a 70% rating in 2018 and the VA re-examined you and kept it at 70% in 2022, the clock runs from 2018 — so by 2023 you already had 5 years of continuous 70% rating protection. The VA's re-examination in 2022 did not restart the clock.
The 10-year rule is found in 38 CFR 3.957, which addresses the "severance" of service connection. Under this regulation, once a service-connected disability has been continuously recognized as service-connected for 10 or more years, the VA cannot sever — i.e., terminate — that service connection unless there is clear and unmistakable evidence that the original grant of service connection was the result of fraud. No other basis is sufficient to sever a 10-year-old service connection.
The 10-year rule is fundamentally different from the 5-year rule in what it protects. The 5-year rule protects the rating level from reduction. The 10-year rule protects the fact of service connection itself. Even after the 10-year mark, the VA can reduce the rating percentage if genuine improvement occurs — it just cannot cut you off entirely from that condition being service-connected. This is an enormously important protection: service connection, once established for 10 years, is effectively permanent.
Consider the practical significance: a veteran with a 30% PTSD rating that has been service-connected since 2014 cannot have that PTSD severed from service connection in 2026 regardless of what any future C&P exam finds. The VA might try to reduce the rating from 30% to 10% based on a favorable exam, and that attempt must still satisfy the 5-year rule — but they cannot eliminate the service connection entirely and cut the veteran off from any PTSD compensation whatsoever.
The only circumstance where the VA can sever service connection after 10 years is "clear and unmistakable evidence" that the original grant was procured through fraud. This is an extremely high evidentiary standard — ordinary dispute about whether service connection was correctly granted is not fraud. The VA must show deliberate misrepresentation, fabrication of evidence, or other affirmative fraudulent conduct. Honest mistakes, differences in medical opinion, or subsequent contrary medical evidence do not constitute fraud sufficient to sever service connection after 10 years. Veterans facing an attempted severance after 10 years should seek immediate legal representation, as such actions are legally extraordinary and often improper.
The 20-year rule is the strongest of the three time-based protections. It is codified in 38 USC 1159 and reinforced by 38 CFR 3.951(b). Under this rule, if a combined disability rating has been continuously held at a certain level for 20 or more years, that level becomes an absolute floor — the VA cannot reduce the combined rating below it. Ever. Regardless of what future examinations show about individual conditions.
The mechanics of the 20-year rule work at the combined rating level. If a veteran has been combined-rated at 70% since 2003, by 2023 the 20-year rule has locked in a 70% floor. The VA can re-examine individual conditions and even reduce some of them — a 30% PTSD might be reduced to 10% if genuine improvement is documented — but as long as the combined total would fall below 70%, the VA cannot finalize the reduction. The combined rating must remain at or above 70% permanently.
One nuance: the 20-year clock runs on the combined rating level continuously held, not on any individual condition. If the combined rating fluctuated — for example, it was 70% from 2000 to 2010, then increased to 80% in 2010, then dropped back to 70% in 2015, then held at 70% through 2026 — the question is whether a specific level was held continuously for 20 years. The 70% floor is established by the longest continuous 20-year run at that level, not by total cumulative time.
The 20-year protection under 38 USC 1159 applies to the combined rating continuously held for 20 years — not to individual condition percentages. The VA can still reduce individual conditions, but the combined total cannot fall below the 20-year floor. Veterans approaching the 20-year mark should carefully track their continuous rating history to ensure they can document the qualifying period.
A Permanent and Total (P&T) designation is the administrative recognition that a veteran's combined 100% rating reflects permanent conditions that are unlikely to improve. P&T is not a separate rating percentage — it is a designation applied to a 100% combined rating. Veterans receive P&T status when the VA determines that their service-connected conditions are static, stabilized, or by their nature cannot be expected to improve.
The legal significance of P&T is that the VA should not schedule future Compensation and Pension (C&P) examinations to reassess the veteran's conditions. Under 38 CFR 3.327, routine re-examinations are not required when they are "not likely to result in a change of rating." P&T veterans fall squarely within this exception — re-examining permanent conditions would be pointless and costly.
P&T designation triggers additional benefit eligibility: CHAMPVA health coverage for dependents, Dependents' Educational Assistance (DEA) under 38 USC Chapter 35, Commissary and Exchange access on military bases, and an expedited Social Security Disability determination pathway. See our dependents benefits guide for full details on CHAMPVA and DEA.
Veterans who hold 100% ratings that are not yet designated P&T can and should request a P&T review if their conditions are clearly permanent in nature. File a written request with your regional office citing the stability of your conditions and asking for a permanent determination. Attach updated medical evidence supporting the permanency of your conditions, including treating physician letters stating no improvement is expected. If denied, appeal through the standard process — the VA must articulate a specific basis for finding that improvement is possible before denying P&T status.
| Protection | What It Covers | Legal Basis | VA Can Still Do | VA Cannot Do |
|---|---|---|---|---|
| 5-Year Rule | Rating level (percentage) | 38 CFR 3.951(b) | Reduce with clear sustained improvement evidence | Reduce based on single exam finding alone |
| 10-Year Rule | Service connection itself | 38 CFR 3.957 | Reduce rating percentage | Sever service connection (absent fraud) |
| 20-Year Rule | Combined rating floor | 38 USC 1159 | Adjust individual condition percentages | Drop combined rating below 20-year floor |
| P&T Designation | Re-examination scheduling | 38 CFR 3.327 | Reduce if clear evidence of improvement | Routinely schedule future C&P exams |
Before the VA can finalize any rating reduction, it is legally required to follow a specific procedural process established under 38 CFR 3.105(e). This process gives the veteran advance notice of the proposed reduction and a meaningful opportunity to challenge it. Skipping or shortcutting this process is a legal error that makes the reduction defective and subject to reversal on appeal.
The required notice must include: (1) the specific rating decision being proposed for reduction; (2) the factual and legal basis for the proposal; (3) the veteran's right to submit evidence within 60 days of the notice; and (4) the veteran's right to request a predetermination hearing within 30 days of the notice. The VA cannot finalize the reduction until the notice and response period have fully elapsed. A reduction issued before the notice period expires, or without adequate notice being given, is procedurally deficient and can be challenged on appeal.
The predetermination hearing right is particularly important and underused. A predetermination hearing is an informal proceeding before a local VA official where the veteran can present evidence and arguments against the proposed reduction. Unlike a formal Board of Veterans' Appeals hearing, the predetermination hearing is relatively quick to schedule and allows you to make your case before the reduction becomes final. Even if you don't ultimately prevail at the predetermination hearing, the hearing creates a record and forces the VA to engage with your evidence before finalizing the reduction.
Receiving a proposed rating reduction notice is alarming, but it is not a final decision. You have clear procedural rights and substantive defenses available. Here's the step-by-step approach to fighting a proposed reduction effectively:
Facing a proposed rating reduction?
Rating reductions are time-sensitive. A VA-accredited attorney can identify which protections apply, gather the right evidence, and file your response within the critical 60-day window. Don't face this alone.

If the VA improperly reduced your rating in the past — years ago, before you knew about these protections — you may be able to challenge that decision through a Clear and Unmistakable Error (CUE) claim. CUE is a special legal doctrine that allows veterans to attack final VA decisions that were wrong at the time they were made, based on a clear misapplication of the law or regulations as they existed at the time of the decision.
Under 38 CFR 3.105(a), a CUE claim can be filed at any time — there is no statute of limitations. If the VA reduced your rating 15 years ago in violation of the 5-year rule (e.g., they reduced a stabilized rating without adequate evidence of sustained improvement), a successful CUE claim would restore your original rating retroactively to the date of the improper reduction. This can mean enormous back pay — potentially decades of compensation at the higher rate. See our CUE claim guide for the full legal standard and how to file.
CUE claims have strict requirements: the alleged error must be undebatable (not just a difference of opinion), it must be based on law and regulations as they existed at the time of the decision, and it must have been outcome-determinative (the correct outcome would have been different if the error hadn't occurred). CUE cannot be used to argue that the VA weighed evidence incorrectly — it requires a clear legal violation. Rating reductions that violated the procedural notice requirements of 38 CFR 3.105(e), or that applied the wrong standard of improvement under 38 CFR 3.951(b), are strong candidates for CUE.
Understanding what triggers a VA re-examination — and therefore a potential reduction — allows veterans to anticipate and prepare. Here are the most common triggers:
Many original rating decisions include language like "A future examination will be scheduled in [timeframe]." This is the VA explicitly building in a re-examination. If you see this language in your rating decision, note the approximate date and begin preparing counter-evidence in advance. The VA's scheduler will typically contact you with an exam notice — but the process is imperfect and notices can be missed, resulting in a missed exam and potential negative consequences.
Some rating categories are specifically temporary — meaning they are designed to be re-evaluated after the acute phase of a condition resolves. These include ratings assigned following surgery (typically re-evaluated 12 months post-operation), ratings for hospitalization (reviewed 6–12 months after discharge), and ratings under certain minimum evaluation rules. When you receive a temporary rating, plan on a re-examination. Having updated evidence ready before the exam is scheduled dramatically improves outcomes.
If a veteran tells the VA — in any context — that their condition has improved, this can trigger a re-examination. This sounds obvious, but veterans sometimes mention improvements casually during unrelated VA appointments or in written communications, not realizing the VA may use this as a basis to schedule a re-evaluation. Always frame treatment progress in terms of functional limitations — "I'm doing well enough to participate in my physical therapy goals" is not the same as "my back is much better now."
After certain medical procedures — particularly surgeries, major medical treatments, or significant medication changes — the VA may schedule a C&P exam to evaluate whether the treatment has improved the service-connected condition. These exams are procedurally authorized and may occur even for veterans with 5-year-protected ratings. Prepare for these exams by thoroughly documenting residual limitations even after treatment success.
Whatever the trigger, the most important thing veterans can do is take C&P examinations seriously. Review the diagnostic criteria in the rating schedule for your conditions before any exam. Bring documentation of your worst days and functional limitations, not just your good-day presentation. See our C&P exam preparation guide for the full strategy.
REE Medical: Build Your Evidence Before Your Next C&P Exam
The best defense against a rating reduction is strong, consistent medical documentation of your ongoing functional limitations. REE Medical's physicians prepare comprehensive evaluations that speak directly to the VA's rating criteria — the same criteria that determine whether a reduction is warranted.

The 5-year rule applies to each individual condition's rating level. A specific condition rated at 30% for 5+ years has its 30% stabilized. If you have five rated conditions, each condition's rating is individually protected once it has been at that level for five years. The VA would need to demonstrate sustained material improvement in that specific condition to justify reducing it, even if other conditions are unprotected. When fighting a proposed reduction, focus your evidence on the specific condition being targeted, not just your overall health picture.
Yes, if the improvement is genuine, sustained, and documented under ordinary conditions of life — not just at a C&P exam. For a rating in place 5+ years, the VA must meet the elevated 38 CFR 3.951(b) standard. If treatment has genuinely resolved or significantly improved your condition, and this is consistently reflected in your daily life and medical records over time, the VA may have valid grounds to reduce. This is why it's important to always document the ongoing functional limitations that persist even when treatment provides some benefit — partial improvement does not justify full reduction.
A rating reduction changes the percentage of your disability rating downward — for example, from 50% to 30%. Your condition remains service-connected, you still receive compensation, just at a lower rate. A rating severance terminates service connection entirely — the VA removes the condition from your record and you receive no compensation for it. The 10-year rule specifically prevents severance (not just reduction) after a decade of continuous service connection. Severance attempts after 10 years are legally extraordinary and almost always improper outside of fraud allegations.
The 20-year protection under 38 USC 1159 creates a floor on the combined rating level continuously held for 20 years. If you voluntarily applied for a reduced rating (a rare circumstance), the continuity might be broken for purposes of the 20-year rule, depending on the circumstances. In practice, veterans almost never seek voluntary rating reductions, so this is largely theoretical. If you are approaching the 20-year mark on a particular combined rating level, do nothing to disrupt the continuity of that rating — no voluntary changes, no waivers — to preserve the protection.
Your original rating decision letter is the primary document. It will state the effective date of the rating — this is the date from which the 5-year, 10-year, and 20-year clocks run. If you don't have your original rating letter, request your claims file (C-file) through a FOIA request to your VA regional office. The C-file contains every rating decision ever issued on your record. You can also access rating history through VA.gov under "Disability compensation" in your profile. Your VSO can help obtain this history if you don't have access to VA.gov.
