ICD-10 Code E04.2 – Nontoxic multinodular goiter (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E04.2 – Nontoxic multinodular goiter
What it is
E04.2 identifies a multinodular enlargement of the thyroid that is not associated with thyrotoxicosis. It means the gland has multiple nodules, but the condition is not toxic.
Clinical signs
Patients may have a visible or palpable enlarged thyroid, often with multiple nodules on exam or imaging. Clinical features vary; refer to documentation.
When to use this code
Use E04.2 when the record clearly documents nontoxic multinodular goiter or multinodular thyroid enlargement without hyperthyroidism. It also fits cases confirmed by imaging or specialist assessment. Check documentation if the chart only says “thyroid nodule” or does not specify multinodular disease.
Do not use for
Do not use this code for toxic multinodular goiter or other thyroid disorders with hyperthyroidism. It is also not the right choice for a single thyroid nodule unless multinodular disease is documented.
Coding tip
Code E04.2 only when the provider documents both multinodular goiter and absence of thyrotoxicosis.
