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 have a documented history of having an endocrine (hormone-related), nutritional, or metabolic disease in the past. This doesn't mean you currently have an active condition, but rather that you've previously been diagnosed with conditions like diabetes, thyroid disorders, vitamin deficiencies, or other hormone or metabolism-related problems. Healthcare providers use this code to keep track of your medical history, as past conditions can influence current health decisions, treatment plans, and risk assessments for future health issues.

Additional Information

This is a documentation code used for medical record keeping and does not represent a current active disease. The specific past condition should be documented elsewhere in your medical record. This history may influence screening recommendations, medication choices, and overall health management.
