D68.6: Other thrombophilia

Thrombophilia, coded as D68.6 in the ICD-10 WHO 2016 classification, is a medical condition where the blood has an increased tendency to form harmful clots. It's not a disease, but a disorder of the clotting system which can raise your risk of developing clots in veins or arteries. These blood clots can interfere with the regular blood flow and potentially lead to serious medical situations such as pulmonary embolism, deep vein thrombosis, or stroke. While everyone's blood can clot, those with thrombophilia clot excessively. This condition can be inherited or acquired, meaning that it can be passed along in families, or it can result from another disease or condition. Symptoms may vary widely and can include pain or swelling in one leg from deep vein thrombosis or shortness of breath and chest pain from pulmonary embolism. However, some people with thrombophilia don't experience any symptoms until they develop a clot.
