International Classification of Diseases

Last updated: 10/11/2025

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

Fibroadenosis is a benign (non-cancerous) breast condition characterized by the development of fibrous tissue and small cysts in the breast. This specific code indicates the condition affects the right breast. It's also known as fibrocystic breast disease or fibrocystic changes. The condition can cause breast tenderness, lumpiness, or pain, particularly before menstrual periods. While benign, it may require monitoring and can sometimes make breast cancer screening more challenging.

Additional Information

This is a benign condition that does not increase cancer risk significantly, but may require ongoing monitoring. Symptoms may fluctuate with hormonal changes.
