E041 - A single, non-cancerous lump or growth in the thyroid gland that does not produce excess hormones

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code represents a single nodule (lump or growth) found in the thyroid gland that is nontoxic, meaning it does not produce excessive amounts of thyroid hormones. The thyroid is a butterfly-shaped gland in your neck that helps regulate metabolism. A single nodule means there is one distinct lump rather than multiple nodules. Most thyroid nodules are benign (non-cancerous) and may not cause symptoms, though they can sometimes be felt as a lump in the neck or seen on imaging studies.

Additional Information

Most single thyroid nodules are benign and may only require monitoring. Treatment decisions depend on size, characteristics, and symptoms.
