Deficiency of vitamin K

This code signifies an inadequate level of vitamin K in the body, which is essential for blood coagulation. This deficiency can lead to impaired clotting, increasing the risk of bleeding and hemorrhage.

Assign this code when documentation indicates a diagnosed vitamin K deficiency, often evidenced by abnormal coagulation studies (e.g., prolonged PT/INR) or clinical signs of bleeding. It is appropriate for conditions like hemorrhagic disease of the newborn, malabsorption syndromes affecting fat-soluble vitamins, or anticoagulant-induced vitamin K deficiency.

• Ensure the documentation explicitly states "deficiency of vitamin K" or a clinically equivalent diagnosis.
• Distinguish from conditions where vitamin K is administered for therapeutic purposes without a diagnosed deficiency.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity impacting patient care.
