ICD-10 Code E04 – Other nontoxic goiter (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E04 – Other nontoxic goiter
What it is
E04 identifies a noncancerous enlargement of the thyroid gland that is not toxic, meaning it does not cause hyperthyroidism. Use this code when the record documents goiter without a more specific thyroid diagnosis.
Clinical signs
Findings may include a visible or palpable enlarged thyroid, neck fullness, or pressure symptoms such as swallowing discomfort. Clinical features vary; refer to documentation.
When to use this code
Use E04 when the provider documents nontoxic goiter, thyroid enlargement, or goiter NOS and no toxic, nodular, or neoplastic thyroid condition is specified. It may also fit cases noted during exam, imaging, or follow-up when the thyroid is enlarged but function is not described as overactive.
Do not use for
Do not use E04 for toxic goiter, Graves disease, thyroid cancer, or thyroiditis. If the chart specifies multinodular goiter, diffuse goiter, or another defined subtype, code the more specific diagnosis instead.
Coding tip
Check the note for the exact goiter type; specificity often changes the code selection.
