R768 - Unusual immune system markers found in blood test

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 laboratory tests of your blood serum (the liquid part of blood) have detected abnormal levels or types of immune system components that don't fit into more specific diagnostic categories. Your immune system produces various proteins, antibodies, and other substances that can be measured in blood tests. When these measurements fall outside normal ranges or show unusual patterns that suggest an immune system irregularity, but don't match well-defined conditions, this code is used. This finding typically requires further evaluation by a specialist to determine if there's an underlying immune system disorder, autoimmune condition, or other medical issue that needs treatment. The abnormal findings could be related to infections, autoimmune diseases, allergic reactions, or other conditions affecting your immune system.

Additional Information

This is a non-specific code used when immune system abnormalities are detected but don't fit standard diagnostic patterns. Further testing is typically needed to determine the exact cause and appropriate treatment.
