38 CFR § 4.119 lists Diagnostic Code 7906 as “Thyroiditis:” With normal thyroid function (euthyroid), the rating is 0. The note says: manifesting as hyperthyroidism, evaluate as hyperthyroidism, including, but not limited to, Graves' disease (DC 7900); manifesting as hypothyroidism, evaluate as hypothyroidism (DC 7903). Appendix B to Part 4 indexes “Thyroiditis” at 7906.

The rating criteria at each level

7906 Thyroiditis

Rating %: 0

Criteria (verbatim). With normal thyroid function (euthyroid)

Rating %: —

Criteria (verbatim). Note: Manifesting as hyperthyroidism, evaluate as hyperthyroidism, including, but not limited to, Graves' disease (DC 7900); manifesting as hypothyroidism, evaluate as hypothyroidism (DC 7903).

Rating %	Criteria (verbatim)
0	With normal thyroid function (euthyroid)
—	Note: Manifesting as hyperthyroidism, evaluate as hyperthyroidism, including, but not limited to, Graves' disease (DC 7900); manifesting as hypothyroidism, evaluate as hypothyroidism (DC 7903).

The 0 percent line is the percentage printed on DC 7906. The note does not print a second percentage. It names DC 7900 and DC 7903.

Section 3.309(a) lists “Endocrinopathies.” That word is not “Thyroiditis.” Section 3.309(d)(2)(ii) lists “Cancer of the thyroid.” That sentence does not assign DC 7906.

DC 7900 is hyperthyroidism, including, but not limited to, Graves' disease. DC 7903 is hypothyroidism. The DC 7906 note is the direction to evaluate under those codes when thyroiditis manifests as one of them. The hypothyroidism guide quotes this note.

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.

What the words mean in your records

Euthyroid is the 0 percent line

The schedule’s words are “With normal thyroid function (euthyroid).” The parentheses are in the row. The rating cell is 0.

Two manifestations, two codes

The note uses a semicolon. Hyperthyroidism, including but not limited to Graves' disease, is DC 7900. Hypothyroidism is DC 7903. The note says “including, but not limited to,” only in the hyperthyroidism clause.

Endocrinopathies stays a family name

Section 3.309(a) lists “Endocrinopathies” without a diagnostic code in that sentence. The presumption registry leaves that row without a code. DC 7906 is the schedule title for thyroiditis. Cancer of the thyroid is a different sentence, in § 3.309(d)(2)(ii).

Evidence that speaks to each level

0 — normal thyroid function

What the rater needs to see. Thyroiditis with normal thyroid function, which is the word euthyroid on the 0 percent line.

Where that usually lives. The thyroid function studies and the diagnosis.

The note’s two codes

What the rater needs to see. If the record shows thyroiditis manifesting as hyperthyroidism, the DC 7900 evaluation. If it shows hypothyroidism, the DC 7903 evaluation.

Where that usually lives. The same records, read against the code the note names.

Level	What the rater needs to see	Where that usually lives
0 — normal thyroid function	Thyroiditis with normal thyroid function, which is the word euthyroid on the 0 percent line.	The thyroid function studies and the diagnosis.
The note’s two codes	If the record shows thyroiditis manifesting as hyperthyroidism, the DC 7900 evaluation. If it shows hypothyroidism, the DC 7903 evaluation.	The same records, read against the code the note names.

VA’s public DBQ list, checked October 5, 2026, names “Thyroid and Parathyroid” under Endocrinological. A separate form, “Endocrine (Other than Thyroid, Parathyroid or Diabetes Mellitus),” is listed beside it. The file for this code’s heading is Thyroid and Parathyroid.

The exam form

DC 7906 prints a 0 percent line and a note naming DC 7900 and DC 7903. This page does not say the form replaces that note.

Related codes and how they interact

Hypothyroidism has its own guide.

DC 7903 is the code the note names for thyroiditis manifesting as hypothyroidism. Its criteria are on that page. They are not reprinted as extra DC 7906 percentages.

Secondary conditions and presumptions

The 2026-10-01 text of 38 CFR § 3.309 contains “Cancer of the thyroid” and “Endocrinopathies.” It does not contain “thyroiditis.” The endocrinopathies row stays without a diagnostic code.

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 thyroiditis?

Under 38 CFR § 4.119, Diagnostic Code 7906 is 0 percent with normal thyroid function (euthyroid). Manifesting as hyperthyroidism, the note says to evaluate as DC 7900. Manifesting as hypothyroidism, it says to evaluate as DC 7903. Education only. VA decides on the evidence.

Does § 3.309 name thyroiditis?

The 2026-10-01 text does not contain “thyroiditis.” It lists endocrinopathies as a chronic-disease name and cancer of the thyroid as a radiation disease.

FAQ

What percentage does DC 7906 print?

With normal thyroid function (euthyroid), thyroiditis is 0 percent. The note evaluates hyperthyroid manifestations under DC 7900 and hypothyroid manifestations under DC 7903. Education only.

Does the note limit hyperthyroidism to Graves' disease?

The note says “including, but not limited to, Graves' disease (DC 7900).” The hypothyroidism clause names DC 7903 and does not use that “including” phrase.

Section 3.309(a) lists “Endocrinopathies” without assigning DC 7906. The 2026-10-01 text does not contain “thyroiditis.” Cancer of the thyroid is § 3.309(d)(2)(ii).
