ICD-10 Code E04.8 – Other specified nontoxic goiter (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E04.8 – Other specified nontoxic goiter
What it is
E04.8 identifies a noncancerous enlargement of the thyroid that is not toxic and does not fit a more specific goiter code. Use it when the documentation names an “other specified” nontoxic goiter.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a visible or palpable thyroid enlargement, often with no hyperthyroid signs. Imaging or exam findings may describe a diffuse or nodular goiter without toxicity.
When to use this code
Use E04.8 when the provider documents a nontoxic goiter that is specifically described as other specified, atypical, or not otherwise classifiable. It also applies when the record distinguishes the goiter from toxic disease, malignancy, or simple diffuse/nodular forms. Check documentation if the exact subtype is unclear.
Do not use for
Do not use this code for toxic goiter, thyroid cancer, or goiter with hyperthyroidism. If the record states simple goiter or a specific nodular or diffuse subtype, code the documented condition instead.
Coding tip
Confirm the provider’s exact wording; E04.8 is a residual code and should be used only when a more specific goiter code is not supported.
