Athscl unsp type bypass of extrm w intrmt claud, oth extrm

This code signifies the presence of atherosclerosis affecting a bypass graft in an extremity, leading to symptoms of intermittent claudication. The specific type of bypass graft is not documented, and the affected extremity is not further specified beyond being "other." This condition indicates compromised blood flow through the grafted vessel, causing pain or cramping during exercise that is relieved by rest.

Use this code when documentation confirms atherosclerosis within a bypass graft of an extremity, and the patient experiences intermittent claudication. This applies when the specific type of bypass graft (e.g., femoropopliteal, aortobifemoral) is not specified, and the affected extremity is not clearly identified as right or left. Supporting documentation should include physician notes detailing the diagnosis of graft atherosclerosis and the presence of claudication.

• Ensure documentation explicitly states "atherosclerosis of bypass graft" and "intermittent claudication."
• Do not use this code if the specific type of bypass graft or the laterality of the affected extremity is documented; more specific codes exist (e.g., I70.311-I70.313).
• Code any associated complications or underlying conditions, such as diabetes or hypertension, as additional diagnoses.
