ICD-10 Code E04.9 – Nontoxic goiter, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E04.9 – Nontoxic goiter, unspecified
What it is
Nontoxic goiter, unspecified means an enlarged thyroid gland without signs of hyperthyroidism or hypothyroidism. Use this code when the record confirms goiter but does not identify a specific type.
Clinical signs
Clinical features vary; refer to documentation. Common findings include visible or palpable thyroid enlargement, neck fullness, or pressure symptoms, but thyroid hormone excess is not documented.
When to use this code
Use E04.9 when the clinician documents goiter and does not specify diffuse, nodular, or other subtype. It also fits cases where the thyroid enlargement is described as nontoxic and no more precise diagnosis is available. Check documentation if imaging or pathology identifies a specific form.
Do not use for
Do not use this code for toxic goiter, thyrotoxicosis, or a specified thyroid nodule diagnosis. If the chart names a particular goiter type, code that condition instead.
Coding tip
Query for the goiter type when the note only says “thyroid enlargement” or “goiter” and the subtype is unclear.
