Infectious, Immune, and Nutritional Conditions Rating Guide

Infections, immune disorders, and nutritional conditions look like very different problems, but they share one rating framework under 38 CFR § 4.88. Many are rated 100 percent while the disease is active, then re-rated on what they leave behind once the active phase clears. Learn that two-phase pattern once and you understand how the VA scores this whole group, and where the Gulf War and burn-pit presumptives fit. This guide explains the shared rules, then points you to the detailed guide for your specific condition.

The Rules That Decide These Claims

Infectious diseases, immune disorders, and nutritional deficiencies are rated under 38 CFR § 4.88b and 4.89. Instead of one fixed rating table, this group runs on a pattern: score the disease highly while it is doing active damage, then re-score it on the lasting harm once the active phase ends. A few rules shape how that plays out, and they decide far more of these claims than any single number does.

1. Active disease is often rated 100 percent

Many infectious diseases, for example active tuberculosis and certain other infections, are rated 100 percent while the disease is active. The rating then moves to the disease's residuals once the active phase resolves, usually after a mandatory review examination that confirms the disease is no longer active.

2. When the active phase clears, the rating shifts to residuals

Once the active disease is gone, the rating is based on the lasting damage it caused, for example lung, liver, or kidney residuals. Each residual is rated under the body system it affects, not under the infectious-disease code. A cleared infection that scarred the lungs, for instance, is then rated under the respiratory schedule.

3. Some conditions are rated on ongoing symptoms, not an active-versus-residual split

Not everything in this group follows the active-then-residual pattern. Some conditions are rated on ongoing symptoms and functional loss. Chronic fatigue syndrome (DC 6354), for example, is rated on how often and how severely the symptoms restrict your daily activity, not on whether a disease is "active."

4. Nutritional deficiencies are rated on their effects

Nutritional deficiencies are rated on their measurable effects on the body. The rating follows the damage the deficiency causes, so the objective findings, not the deficiency label alone, drive the level.

5. Several conditions here are Gulf War and burn-pit presumptives

A number of conditions in this group are Gulf War and burn-pit presumptives. For covered veterans with qualifying service, the VA presumes the link to service, so you often do not have to prove the medical connection yourself. See the PACT Act guide and the Gulf War illness guide for who and what qualifies.

Two ratings over time, one condition. With the active-then-residual pattern, one disease can carry a 100 percent rating during its active phase and a different rating on its residuals afterward. When the active phase ends and the 100 percent stops, filing for the residuals is a separate step, the residual damage does not rate itself automatically.

Common Secondary Conditions

Infections and immune disorders rarely stay contained to one system. Because they can damage organs and wear a person down over time, one service-connected condition often opens the door to several secondary claims:

  • Organ residuals. After an infection resolves, the lung, liver, or kidney damage it left behind is rated under its own body system as a separate condition.
  • Chronic fatigue and pain. Lasting fatigue and pain can overlap with a mental-health condition, and each can be claimed in its own right.
  • Conditions from long-term immunosuppression. Treatments that suppress the immune system can lead to further conditions that may be claimed as secondary.
  • Depression secondary to a chronic condition. Living with a chronic infectious or immune condition can drive depression and anxiety, which can be claimed as secondary to the physical condition. See secondary conditions.

Each dedicated guide above shows the live Board grant rates for that condition's most common secondary pairings.

Evidence That Wins

  • Laboratory confirmation of the infection or immune disorder, the objective proof the diagnosis rests on.
  • Records dating the active phase and the residuals, so the file clearly shows when the disease was active and what damage remained afterward.
  • A symptom log for chronic fatigue syndrome, a dated record of how often and how severely symptoms restrict your daily activity, which is what sets the rating.
  • Proof of qualifying Gulf War or burn-pit service for the presumptive path, so the VA can presume the link instead of asking you to prove it.
  • The matching DBQ for the condition, which prompts the examiner to capture the findings the rating depends on. See the DBQ guide.

Common Mistakes

  • Not filing for the residuals. When the active disease resolves and the 100 percent ends, the lasting organ damage does not rate itself. Filing for the residuals is a separate step that is easy to miss.
  • Missing the Gulf War presumptive. An undiagnosed illness or chronic fatigue can qualify under the Gulf War presumptive, so covered veterans should not try to prove a medical link the law already presumes.
  • No symptom log. Without a dated record of how often symptoms flare and how bad they get, the frequency that sets a chronic-fatigue rating is left unproven.
  • Rating organ damage under the wrong schedule. Lung, liver, or kidney residuals belong under the system they actually affect, not under the infectious-disease code.

Frequently Asked Questions

How does the VA rate infectious diseases?
Many are rated in two phases under 38 CFR 4.88. While the disease is active, it is often rated 100 percent. Once the active phase resolves, usually confirmed by a mandatory review examination, the rating moves to the residuals, the lasting lung, liver, kidney, or other damage the disease left behind, each rated under the body system it affects.
What is the Gulf War presumptive?
For veterans with qualifying Gulf War service, the VA presumes that certain conditions, including undiagnosed illnesses and chronic fatigue, are connected to service. That means you often do not have to prove the medical link yourself. The PACT Act and Gulf War illness guides explain who and what qualifies.
How is chronic fatigue syndrome rated?
Chronic fatigue syndrome (DC 6354) is rated on how often and how severely the symptoms restrict your daily activity, rather than on an active-versus-residual split. A dated symptom log showing the frequency and severity of your flare-ups is the evidence that supports the rating.
Do I get 100 percent while an infection is active?
For many infectious diseases, yes, the condition is rated 100 percent while it is active. That 100 percent is tied to the active phase. When the active disease clears, the rating shifts to the residuals, which are rated on the lasting damage under the body system involved. Exact levels are on each condition lookup page.
What happens at the mandatory review exam?
After a period at 100 percent for an active infectious disease, the VA schedules a mandatory review examination to check whether the disease is still active. If it has resolved, the rating is re-evaluated on the residuals, the lasting damage that remains, rather than staying at the active-disease rate.
