International Classification of Diseases

Last updated: 3/24/2026

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 is used when blood chemistry tests show abnormal results that don't fit into other specific diagnostic categories. Blood chemistry tests measure various substances in your blood like proteins, enzymes, minerals, and other chemicals. When these tests show unusual values that your doctor needs to document but that don't match other specific diagnostic codes, this general code is used. The abnormal findings could relate to various blood components and may require further testing or monitoring to determine their significance.

Additional Information

This is a non-specific code used for documentation purposes when blood chemistry results are abnormal but don't fit other specific diagnostic categories. The clinical significance varies depending on which specific blood chemistry values are abnormal and by how much.
