The rating criteria at each level

7901 Thyroid enlargement, toxic

Rating %: —

Criteria (verbatim). Note (1): Evaluate symptoms of hyperthyroidism under DC 7900, hyperthyroidism, including, but not limited to, Graves' disease.

Rating %: —

Criteria (verbatim). Note (2): If disfigurement of the neck is present due to thyroid disease or enlargement, separately evaluate under DC 7800 (burn scar(s) of the head, face, or neck; scar(s) of the head, face, or neck due to other causes; or other disfigurement of the head, face, or neck).

Rating %	Criteria (verbatim)
—	Note (1): Evaluate symptoms of hyperthyroidism under DC 7900, hyperthyroidism, including, but not limited to, Graves' disease.
—	Note (2): If disfigurement of the neck is present due to thyroid disease or enlargement, separately evaluate under DC 7800 (burn scar(s) of the head, face, or neck; scar(s) of the head, face, or neck due to other causes; or other disfigurement of the head, face, or neck).

Both notes end with a period. Note (1) names DC 7900 and Graves' disease. Note (2) repeats the DC 7800 title in parentheses and says to separately evaluate.

DC 7901 does not print a percentage of its own. The percentages, if any, are on the codes the notes name.

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. 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.

DC 7902 is “Thyroid enlargement, nontoxic:”. Its Note (2) is the same disfigurement sentence. Its Note (1) is about pressure on adjacent organs. It does not name DC 7900. The DC 7902 page already records that difference.

The 2026-10-01 text of 38 CFR § 3.309 lists “Endocrinopathies” and, in paragraph (d), “Cancer of the thyroid.” It does not contain “7901” and it does not assign this code. This page does not add DC 7901 to a presumptive row.

What the words mean in your records

Toxic is the title

The schedule word is “toxic.” Nontoxic enlargement is DC 7902. Its first note is not this hyperthyroidism sentence.

Graves' disease is an example

Note (1) says hyperthyroidism, including, but not limited to, Graves' disease. The evaluation it names is under DC 7900.

DC 7800 is named in full

Note (2) repeats the DC 7800 title inside the parentheses. It says “separately evaluate.”

Evidence that speaks to each level

Note (1)

What the rater needs to see. Symptoms of hyperthyroidism, including Graves' disease when that is the diagnosis.

Where that usually lives. The DC 7900 evaluation. DC 7901 does not print the DC 7900 percentages.

Note (2)

What the rater needs to see. Disfigurement of the neck due to thyroid disease or enlargement.

Where that usually lives. The separate DC 7800 evaluation.

Level	What the rater needs to see	Where that usually lives
Note (1)	Symptoms of hyperthyroidism, including Graves' disease when that is the diagnosis.	The DC 7900 evaluation. DC 7901 does not print the DC 7900 percentages.
Note (2)	Disfigurement of the neck due to thyroid disease or enlargement.	The separate DC 7800 evaluation.

VA’s public DBQ list, checked October 5, 2026, names “Thyroid and Parathyroid” under Endocrinological. The file is Thyroid and Parathyroid.

The exam form

DC 7901 prints two notes and no percentage. This page does not say the form replaces those notes.

Related codes and how they interact

Hyperthyroidism is DC 7900

DC 7900 is the code Note (1) names. DC 7800 is the code Note (2) names. DC 7902 is nontoxic thyroid enlargement.

Secondary conditions and presumptions

Section 3.309 lists “Endocrinopathies” and “Cancer of the thyroid.” It does not assign DC 7901. This page does not add DC 7901 to a presumptive row.

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.

Does § 3.309 assign this code to cancer of the thyroid?
