ICD-10 Code E07.8 – Other specified disorders of thyroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E07.8 – Other specified disorders of thyroid
What it is
E07.8 identifies thyroid disorders that do not fit a more specific ICD-10 category. Use it for documented thyroid conditions that are not otherwise classified in the record.
Clinical signs
Clinical features vary; refer to documentation. Patients may have nonspecific thyroid-related findings, but the chart should name the disorder or describe why a more specific code does not apply.
When to use this code
Use E07.8 when the provider documents an unusual or specified thyroid disorder that has no exact matching code. It is appropriate when the diagnosis is clear, but the available ICD-10 options are too limited or do not describe the condition precisely. Check documentation if the note is vague.
Do not use for
Do not use this code for common thyroid disorders with dedicated codes, such as hypothyroidism, hyperthyroidism, thyroiditis, or thyroid nodules. If the condition is unspecified or better described elsewhere, choose the more accurate code.
Coding tip
Before assigning E07.8, confirm the provider’s exact thyroid diagnosis and compare it with the specific thyroid codes already available.
