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 indicates that you are currently taking hormone replacement therapy on a long-term basis. Hormone replacement therapy involves taking medications that contain hormones to replace those that your body no longer produces adequately. This is commonly prescribed for conditions like menopause, where estrogen and progesterone levels drop, or for other hormonal deficiencies. The code is used to document your ongoing HRT treatment in your medical records, which helps healthcare providers coordinate your care and be aware of potential interactions with other medications or treatments.

Additional Information

This is a documentation code used to track ongoing hormone therapy. The actual cost depends on the specific hormones prescribed, dosage, and insurance coverage. Regular monitoring is important to ensure safe and effective treatment.
