38 CFR § 4.88b lists Diagnostic Code 6316 as “Brucellosis.” The code says to evaluate under the General Rating Formula for Infectious Diseases. Note 1 says culture, serologic testing, or both must confirm the initial diagnosis and recurrence of active infection. Note 2 rates residuals and names meningitis, liver, spleen and musculoskeletal conditions. Section 3.317(c)(2)(i) lists “Brucellosis.”

The rating criteria at each level

General Rating Formula for Infectious Diseases — DC 6316 says to evaluate under this formula

Rating %: 100

Criteria (verbatim). For active disease

Rating %: —

Criteria (verbatim). After active disease has resolved, rate at 0 percent for infection. Rate any residual disability of infection within the appropriate body system.

Rating %	Criteria (verbatim)
100	For active disease
—	After active disease has resolved, rate at 0 percent for infection. Rate any residual disability of infection within the appropriate body system.

Note 1: Culture, serologic testing, or both must confirm the initial diagnosis and recurrence of active infection.

Note 2: Rate under the appropriate body system any residual disability of infection, which includes, but is not limited to, meningitis, liver, spleen and musculoskeletal conditions.

DC 6316’s own row does not print a percentage. It says: “Evaluate under the General Rating Formula.” The second line of the General Rating Formula does not print a number in the rating column. The words “rate at 0 percent” are inside the criteria cell. The cell also says to rate any residual disability of infection within the appropriate body system. 38 CFR § 4.7 assigns the higher rating when the disability picture more nearly approximates the criteria required for that rating. Otherwise, the lower rating will be assigned. 38 CFR § 4.6 requires each element affecting the evidence to be studied so that decisions will be equitable and just.

The opening note of § 4.88b says to rate any residual disability of infection within the appropriate body system as indicated by the notes in the evaluation criteria. It then says, as applicable, to consider the long-term health effects potentially associated with infectious diseases as listed in § 3.317(d), specifically Brucellosis, Campylobacter jejuni, Coxiella burnetii (Q fever), Malaria, Mycobacterium Tuberculosis, Nontyphoid Salmonella, Shigella, Visceral Leishmaniasis, and West Nile virus. The opening note also names Mycobacterium Tuberculosis. DC 6316 is not that name. DC 6311 is “Tuberculosis, miliary.” The 2026-10-01 schedule titles tuberculosis under more than one code, so § 3.317(c)(2)(v) is not assigned here.

What the words mean in your records

Active disease, then the resolved-infection line

The formula’s 100 percent line is “For active disease.” The next line has no number in the rating column. It says to rate at 0 percent for the infection after active disease has resolved, and to rate any residual disability of infection within the appropriate body system.

The schedule title and the § 3.317 name

Section 3.317(c)(2)(i) says “Brucellosis.” The schedule title at DC 6316 is “Brucellosis.”

The note and the table do not use the same words

Note 2’s examples are “meningitis, liver, spleen and musculoskeletal conditions.” The phrase has no comma before “and.” The column B list under Brucellosis is a different list. It includes “Chronic meningitis and meningoencephalitis” and does not print Note 2’s phrase “liver, spleen and musculoskeletal conditions.” The note says “including, but is not limited to.” The table is the paragraph (d) list. It is not the rating note.

Evidence that speaks to each level

100 — for active disease

What the rater needs to see. Active disease. That is the formula’s 100 percent line. The line says “For active disease.”

Where that usually lives. The record that describes active disease, including the confirmation the note requires when it requires one.

After active disease has resolved

What the rater needs to see. The unnumbered formula line: rate at 0 percent for the infection, and rate any residual disability of infection within the appropriate body system. The DC 6316 note states the residual examples printed under that code.

Where that usually lives. The examination of the body system used for the residual.

Level	What the rater needs to see	Where that usually lives
100 — for active disease	Active disease. That is the formula’s 100 percent line. The line says “For active disease.”	The record that describes active disease, including the confirmation the note requires when it requires one.

VA’s public DBQ list, checked October 5, 2026, names “Infectious Diseases (other than HIV-related illness chronic fatigue syndrome and tuberculosis)” under Infectious Diseases, and, separately, “Persian Gulf/Afghanistan Infectious Diseases.” The files are Infectious Diseases (other than HIV-related illness chronic fatigue syndrome and tuberculosis) and Persian Gulf/Afghanistan Infectious Diseases. The public list prints the infectious-disease title without commas between “HIV-related illness,” “chronic fatigue syndrome,” and “tuberculosis.”

The exam form

DC 6316 says to evaluate under the General Rating Formula and prints the note under that code. This page does not say either form replaces those lines.

Related codes and how they interact

The formula is shared. The note is not.

Several codes in § 4.88b say to evaluate under the same formula. The residual examples under DC 6316 are the ones printed on that code. DC 6304 names liver or splenic damage and central nervous system conditions. That list is not this note. 38 CFR § 4.14 says the evaluation of the same disability under various diagnoses is to be avoided, and that the evaluation of the same manifestation under different diagnoses is to be avoided.

Secondary conditions and presumptions

38 CFR § 3.317(c)(2)(i) lists “Brucellosis.” Paragraph (c)(1) says a disease listed in paragraph (c)(2) will be service connected if it becomes manifest in a veteran with a qualifying period of service, provided paragraph (c)(3) is also satisfied, except as paragraph (c)(4) provides.

38 CFR § 3.317(c)(3)(i) says, with three exceptions, the disease must have become manifest to a degree of 10 percent or more within 1 year from the date of separation from a qualifying period of service as specified in paragraph (c)(3)(ii). The same paragraph then says malaria must have become manifest to a degree of 10 percent or more within 1 year from that separation, or at a time when standard or accepted treatises indicate that the incubation period commenced during a qualifying period of service. It then says there is no time limit for visceral leishmaniasis or tuberculosis to have become manifest to a degree of 10 percent or more. Paragraph (c)(3)(ii) defines a qualifying period of service as a period meeting paragraph (e), or active military, naval, or air service on or after September 19, 2001, in Afghanistan. Paragraph (c)(4) says a listed disease shall not be presumed service connected if there is affirmative evidence that it was not incurred during a qualifying period of service, that a supervening condition or event caused it between the most recent departure from that service and the onset of the disease, or that it is the result of the veteran’s own willful misconduct or the abuse of alcohol or drugs. Brucellosis is not malaria, visceral leishmaniasis, or tuberculosis. The one-year sentence is the general rule in that paragraph. The no-time-limit sentence names visceral leishmaniasis and tuberculosis. DC 6301 is visceral leishmaniasis. DC 6304 is malaria.

The table to § 3.317, column B under Brucellosis, prints: Arthritis; Cardiovascular, nervous, and respiratory system infections; Chronic meningitis and meningoencephalitis; Deafness; Demyelinating meningovascular syndromes; Episcleritis; Fatigue, inattention, amnesia, and depression; Guillain-Barré syndrome; Hepatic abnormalities, including granulomatous hepatitis; Multifocal choroiditis; Myelitis-radiculoneuritis; Nummular keratitis; Papilledema; Optic neuritis; Orchioepididymitis and infections of the genitourinary system; Sensorineural hearing loss; Spondylitis; and Uveitis. 38 CFR § 3.317(d)(2) says that if a veteran presumed service connected for one of the diseases listed in paragraph (c)(2) is diagnosed with one of the diseases listed in column B of the table to § 3.317, within the time period specified for that disease in the table if a time period is specified, or otherwise at any time, VA will request a medical opinion as to whether it is at least as likely as not that the column B condition was caused by the veteran having had the associated disease in column A. That paragraph is not a rating percentage.

The 2026-10-01 text of 38 CFR § 3.309(a) does not name Brucellosis. 38 CFR § 3.309(b) does not name Brucellosis. 38 CFR § 3.309(c) does not name Brucellosis. 38 CFR § 3.309(e) does not name Brucellosis. 38 CFR § 3.309(f) does not name Brucellosis. 38 CFR § 3.316 does not name Brucellosis. 38 CFR § 3.320 does not name Brucellosis. 38 CFR § 3.320a does not name Brucellosis. 38 CFR § 3.320b does not name Brucellosis. 38 CFR § 3.309(b) lists “Malaria.” It does not list “Brucellosis.”

A separate question, when a presumption does not decide it, is a medical question on the facts under 38 CFR § 3.310. Paragraph (a) covers disability proximately due to or the result of a service-connected disease or injury. Paragraph (b) covers increase in severity and requires a medical baseline.

Short answers

What is the VA rating for DC 6316?

Under 38 CFR § 4.88b, Brucellosis is evaluated under the General Rating Formula for Infectious Diseases: 100 percent for active disease, then 0 percent for the infection after active disease has resolved, with residuals rated under the appropriate body system. Education only. VA decides on the evidence.

Is Brucellosis a chronic disease under § 3.309(a)?

Section 3.309(a) does not name Brucellosis. Section 3.317(c)(2)(i) does, for a qualifying period of service under that section.

FAQ

How does VA rate DC 6316?

The code says to evaluate under the General Rating Formula for Infectious Diseases. Active disease is 100 percent. After active disease has resolved, the formula says to rate at 0 percent for the infection and to rate residuals under the appropriate body system. The note under DC 6316 prints the residual examples for this code. Education only.

Which presumption names Brucellosis?

Section 3.317(c)(2)(i) lists it for a qualifying period of service, with the time rule in paragraph (c)(3)(i). Brucellosis is not malaria, visceral leishmaniasis, or tuberculosis. The one-year sentence is the general rule in that paragraph. The no-time-limit sentence names visceral leishmaniasis and tuberculosis. DC 6301 is visceral leishmaniasis. DC 6304 is malaria. Section 3.309(a), (b), (c), (e), and (f) do not name it.

Does the § 3.317 table assign a percentage?

No. Paragraph (d)(2) says VA will request a medical opinion on whether a column B condition was caused by the infectious disease. The rating instruction for residuals is the note under DC 6316 and the second line of the General Rating Formula.
