How the VA Rates Cancer for Disability Compensation

For veterans diagnosed with cancer, one of the most common questions is also one of the most misunderstood: how does the Department of Veterans Affairs decide what a cancer is "worth" in disability compensation? The short answer is that the VA generally treats an active, service-connected cancer very differently from a cancer that has been treated and is in remission. Understanding that distinction helps explain why a rating that starts at the maximum can later change, and why that change is usually not a sign that anything has gone wrong.

Active cancer is generally rated at 100 percent

When a service-connected cancer is active, the VA generally assigns a total, or 100 percent, disability rating while the veteran is under active treatment and for a defined period afterward. This is written directly into the rating schedule. For genitourinary cancers, for example, 38 CFR 4.115b, diagnostic code 7528 assigns a 100 percent rating during active malignancy and for six months following the cessation of surgical, X-ray, antineoplastic chemotherapy, or other therapeutic treatment. Similar 100 percent provisions appear for respiratory cancers under 38 CFR 4.97, diagnostic code 6819, and for digestive cancers under 38 CFR 4.114, diagnostic code 7343. The principle is consistent across body systems, even though the exact diagnostic code differs depending on where the cancer is located.

The six-month re-examination and the shift to residuals

The 100 percent rating for active cancer is generally not permanent. The rating schedule typically calls for a mandatory VA re-examination roughly six months after treatment ends. At that exam, the VA looks at whether there has been any local recurrence or metastasis. If the cancer has recurred or spread, the 100 percent rating may continue. If, in most cases, there has been no recurrence or metastasis, the VA stops rating the cancer itself and instead rates the residuals, meaning the lasting damage the cancer and its treatment left behind in the affected body system.

This shift is the part that surprises many veterans. A rating may drop from 100 percent to something lower not because the VA doubts the diagnosis, but because the law directs it to compensate the remaining functional loss rather than a malignancy that is no longer active. The VA must generally follow specific procedures before reducing a rating, and the re-examination is the mechanism the regulations use to make that determination.

How residuals are rated under 38 CFR Part 4

Residuals are rated under the diagnostic code for whatever body system was affected, using the same schedule the VA uses for non-cancer conditions. The genitourinary regulation is a clear example: once a prostate, bladder, or kidney cancer is in remission, 38 CFR 4.115b directs the VA to rate the predominant residual, such as voiding dysfunction or renal (kidney) dysfunction, whichever is the more disabling. Under that framework, voiding dysfunction does not generally rise above a 60 percent evaluation, while renal dysfunction can in some cases support a higher figure. For respiratory cancers, residuals such as reduced breathing capacity are evaluated under the respiratory schedule; for digestive cancers, the residual digestive impairment is rated under 38 CFR 4.114. The exact percentage a veteran receives depends on the specific findings documented at examination, so it is best estimated, not assumed. Our disability calculator can help illustrate how a residual rating might combine with a veteran's other service-connected conditions.

Service connection and the rating percentage are two separate steps

It is worth separating two questions that veterans often blend together. The first is whether a cancer is service connected at all. The second is what percentage it is rated. Presumptive service connection answers only the first question. Under the PACT Act, the VA treats many cancers, including respiratory cancers, reproductive cancers, kidney cancer, pancreatic cancer, and others, as presumptively linked to toxic exposures such as burn pit smoke, so a qualifying veteran does not have to prove the connection from scratch. Similar presumptions apply for Agent Orange and for Camp Lejeune contaminated water exposure, where the VA recognizes a set of presumptive conditions for disability compensation.

Establishing a presumption, however, says nothing about the rating percentage. Once a cancer is service connected, whether by presumption or by direct evidence, it still moves through the same active-then-residual rating process described above. A presumptive cancer is not automatically a permanent 100 percent rating. The claims process for toxic exposure and our presumptive conditions tool can help veterans see which exposures and conditions may apply.

SMC and TDIU, briefly

Two additional pathways can matter when residuals are severe. Special monthly compensation (SMC) is a higher rate the VA pays in certain circumstances, such as the need for aid and attendance from another person or the loss of use of a body part, and some SMC amounts can be added on top of a regular rating. Total disability based on individual unemployability (TDIU) allows the VA to pay at the 100 percent rate when service-connected disabilities prevent a veteran from holding substantially gainful employment, even if the combined schedular rating is below 100 percent. Under 38 CFR 4.16, TDIU generally requires either one disability rated at 60 percent or a combined rating of 70 percent with at least one disability at 40 percent, though cases that fall short can in some instances be considered on an extraschedular basis. These are separate claims and worth raising if cancer residuals limit a veteran's ability to work.

What veterans should do

The practical steps are straightforward. Keep thorough records of treatment, including surgery, chemotherapy, radiation, and follow-up imaging, because those records define both the active period and the residuals. Attend the compensation and pension (C and P) examination, including the six-month re-examination, since a missed exam can affect the rating. Finally, consider working with an accredited Veterans Service Organization (VSO), which can help free of charge with filing, evidence, and any disagreement with a decision. More general guidance is collected on our resources page. None of this is legal or medical advice, and veterans with specific questions should consult the VA or an accredited representative directly.
