Athscl unsp type bypass of extrm w intrmt claud, right leg

This code signifies atherosclerosis affecting a bypass graft in the right leg, specifically when the patient experiences intermittent claudication. It indicates a narrowing or hardening of a previously placed vascular graft in the lower extremity, leading to pain or cramping during exercise that resolves with rest.

Use this code for patients presenting with symptoms of intermittent claudication due to atherosclerotic disease within a bypass graft of the right leg. Documentation should clearly state the presence of a bypass graft, its location in the right leg, and the diagnosis of atherosclerosis with associated intermittent claudication.

• Ensure documentation specifies "unspecified type" of bypass graft if the graft type (e.g., femoropopliteal, aortofemoral) is not explicitly stated.
• Confirm the laterality is clearly documented as "right leg" to avoid incorrect limb assignment.
• Do not use this code if the atherosclerosis is in a native vessel; use codes from the I70.2- or I70.4- series instead.
