D6851 - A blood clotting disorder that increases the risk of developing blood clots

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

Activated Protein C Resistance is a genetic condition where your blood doesn't respond properly to a natural protein (Protein C) that helps prevent blood clots. This means your blood has a higher tendency to form clots than normal. The most common cause is a genetic variation called Factor V Leiden. People with this condition have an increased risk of developing blood clots in their veins, particularly in the legs (deep vein thrombosis) or lungs (pulmonary embolism). The condition is usually discovered through blood tests, often after someone has had a blood clot or during screening if there's a family history of clotting disorders.

Additional Information

This is typically a lifelong condition that requires ongoing management. Treatment focuses on preventing blood clots rather than curing the condition. Risk factors like prolonged sitting, surgery, pregnancy, or certain medications may require special precautions.
