Coding Different Types of Vascular Disease – A Look at the Related ICD-10 Codes

Peripheral vascular diseases are conditions affecting the circulatory system, or system of blood vessels. These range from diseases of the arteries, veins and lymph vessels to blood disorders that affect circulation. These disorders affect blood flow through the arteries and/or the veins, most commonly the legs. However, the location of the pain will depend on the site of the narrowed or clogged artery. Vascular surgeons treating patients with health concerns ranging from life-threatening conditions like abdominal aortic aneurism to minor conditions like varicose veins, have to document all the diagnostic test results and any clinical findings that support the treatments provided. Vascular medical coding involves reporting the condition and treatments provided using the right diagnosis and procedure codes on the medical claims.

Peripheral vascular diseases are caused by blockage of arteries. Key factors that can increase the risk of getting a vascular disease include high blood pressure, gender, family history, genetics, poor physical activity, overweight or obesity, smoking and stress.

Symptoms can vary depending on the type of vascular disease. Common symptoms include leg pain or cramps with activity, high blood pressure, congestive heart failure and abnormal kidney function, leg and foot cramps, numbness, tingling, discoloration, pain in the arms, hands, legs and feet, shortness of breath, chest pain, and dizziness.
