38 CFR § 4.88b lists Diagnostic Code 6313 as “Avitaminosis.” The percentage lines are 100, 60, 40, 20, and 10. The code does not say to evaluate under the General Rating Formula for Infectious Diseases. Section 3.309(c)(2) lists “Avitaminosis” for a former prisoner of war interned or detained for not less than 30 days. Section 3.309(c)(1) does not list it. DC 6315, pellagra, prints the same five percentage lines.

The rating criteria at each level

Avitaminosis — DC 6313

Rating %: 100

Criteria (verbatim). Marked mental changes, moist dermatitis, inability to retain adequate nourishment, exhaustion, and cachexia

Rating %: 60

Criteria (verbatim). With all of the symptoms listed below, plus mental symptoms and impaired bodily vigor

Rating %: 40

Criteria (verbatim). With stomatitis, diarrhea, and symmetrical dermatitis

Rating %: 20

Criteria (verbatim). With stomatitis, or achlorhydria, or diarrhea

Rating %: 10

Criteria (verbatim). Confirmed diagnosis with nonspecific symptoms such as: decreased appetite, weight loss, abdominal discomfort, weakness, inability to concentrate and irritability

Rating %	Criteria (verbatim)
100	Marked mental changes, moist dermatitis, inability to retain adequate nourishment, exhaustion, and cachexia
60	With all of the symptoms listed below, plus mental symptoms and impaired bodily vigor
40	With stomatitis, diarrhea, and symmetrical dermatitis
20	With stomatitis, or achlorhydria, or diarrhea
10	Confirmed diagnosis with nonspecific symptoms such as: decreased appetite, weight loss, abdominal discomfort, weakness, inability to concentrate and irritability

DC 6313 does not print a 0 percent line and does not say to evaluate under the General Rating Formula. 38 CFR § 4.31 says: “In every instance where the schedule does not provide a zero percent evaluation for a diagnostic code, a zero percent evaluation shall be assigned when the requirements for a compensable evaluation are not met.” 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 60 percent line says “with all of the symptoms listed below.” The lines printed under it are the 40, 20, and 10 percent lines. The 100 percent line uses commas and “and” before cachexia. The 40 percent line uses “and” among stomatitis, diarrhea, and symmetrical dermatitis. The 20 percent line uses “or.”

The 10 percent line says “such as:” before decreased appetite, weight loss, abdominal discomfort, weakness, inability to concentrate and irritability. The code does not print a residual note.

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. Avitaminosis is not one of those names.

What the words mean in your records

Five lines, and no formula pointer

The percentages are 100, 60, 40, 20, and 10. DC 6313 does not say “Evaluate under the General Rating Formula.” The formula’s “For active disease” line is for codes that direct the rater there.

The same five lines are printed on DC 6315

DC 6315 is pellagra. The 2026-10-01 text prints the same five criteria sentences and the same five percentages. The titles are different. Section 3.309(c)(2) lists “Avitaminosis” and “Pellagra” as separate names. It also lists “Any other nutritional deficiency” as a separate name.

The 30-day rule is paragraph (c)(2)

Avitaminosis is in § 3.309(c)(2), with the “not less than 30 days” requirement. Paragraph (c)(1) does not list avitaminosis and does not use that 30-day sentence. DC 6314 is beriberi, which is also a paragraph (c)(2) name and uses different percentage lines.

Evidence that speaks to each level

100

What the rater needs to see. Marked mental changes, moist dermatitis, inability to retain adequate nourishment, exhaustion, and cachexia. The line uses “and” before cachexia.

Where that usually lives. The examination that records those findings.

60, 40, or 20

What the rater needs to see. At 60, all of the symptoms listed below, plus mental symptoms and impaired bodily vigor. At 40, stomatitis, diarrhea, and symmetrical dermatitis. At 20, stomatitis, or achlorhydria, or diarrhea.

Where that usually lives. The clinical note that matches the line.

What the rater needs to see. A confirmed diagnosis with nonspecific symptoms such as decreased appetite, weight loss, abdominal discomfort, weakness, inability to concentrate and irritability.

Where that usually lives. The diagnosis and the symptom description.

VA’s public DBQ list, checked October 5, 2026, names “Nutritional Deficiencies.” The file is Nutritional Deficiencies. The section heading of 38 CFR § 4.88b is “Schedule of ratings—infectious diseases, immune disorders and nutritional deficiencies.”

The exam form

DC 6313 prints five percentage lines and does not print a residual note. This page does not say the form replaces those lines.

Related codes and how they interact

Pellagra uses the same percentages

DC 6315 prints the same 100, 60, 40, 20, and 10 percent sentences. The schedule still titles them separately. Section 3.309(c)(2) lists both names, and it lists “Any other nutritional deficiency” as its own item. That item is not assigned to DC 6313.

Secondary conditions and presumptions

38 CFR § 3.309(c)(2) says: “If the veteran: (i) Is a former prisoner of war and; (ii) Was interned or detained for not less than 30 days, the following diseases shall be service connected if manifest to a degree of 10 percent or more at any time after discharge or release from active military, naval, air or space service even though there is no record of such disease during service, provided the rebuttable presumption provisions of § 3.307 are also satisfied.” “Avitaminosis” is in that list.

38 CFR § 3.307(a)(5) says the diseases listed in § 3.309(c) shall have become manifest to a degree of 10 percent or more at any time after discharge or release from active service. 38 CFR § 3.307(a)(1) says any period of service is sufficient for the purpose of establishing the presumptive service connection of a specified disease under the conditions listed in § 3.309(c) and (e). The 90-day sentence in that paragraph is not the sentence for § 3.309(c). Paragraph (c)(2) of § 3.309 is the paragraph that adds the 30-day internment or detention requirement. Paragraph (c)(1) does not list avitaminosis.

Section 3.309(a) does not name avitaminosis. Section 3.309(b) does not name it. The 2026-10-01 text of 38 CFR § 3.309(e) does not name avitaminosis. 38 CFR § 3.309(f) does not name avitaminosis. 38 CFR § 3.309(d) does not name avitaminosis. 38 CFR § 3.320 does not name avitaminosis. 38 CFR § 3.320a does not name avitaminosis. 38 CFR § 3.320b does not name avitaminosis. 38 CFR § 3.316 does not name avitaminosis. 38 CFR § 3.317 does not name avitaminosis.

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
