Personal history of other diseases of the circulatory system

This code indicates a patient's past medical history of a circulatory system condition that is not specifically categorized elsewhere. It signifies that the patient previously experienced a heart or blood vessel disease, but it is no longer active or being treated as a current primary diagnosis. This history can still impact current care decisions and risk assessments.

Apply this code when documentation indicates a resolved or inactive circulatory system disease that doesn't have a more specific history code (e.g., history of myocardial infarction). This is appropriate for conditions like a past episode of transient ischemic attack (TIA) when the patient is not currently experiencing symptoms, or a history of peripheral artery disease that is now stable and not requiring active management.

• Do not use this code for active circulatory conditions; instead, code the specific active disease.
• Ensure the documentation clearly states the condition is a history and not a current problem.
• Review for more specific history codes (e.g., personal history of venous thrombosis and embolism) before defaulting to this general code.
