Oth athscl native arteries of extremities, right leg

This code signifies the presence of atherosclerosis, a hardening and narrowing of the arteries due to plaque buildup, affecting the native (non-grafted) arteries of the right lower extremity. This condition restricts blood flow to the right leg, potentially leading to symptoms like claudication, rest pain, or non-healing ulcers.

Use this code when documentation specifies atherosclerosis in the native arteries of the right leg, and the condition is not further specified as a specific type (e.g., with gangrene, with ulceration). This code is appropriate for peripheral artery disease (PAD) affecting the right leg without more severe complications.

• Ensure documentation clearly specifies "right leg" and "native arteries" to support this code.
• Distinguish from atherosclerosis of bypass graft(s) of the extremities, which have different code categories.
• If the atherosclerosis is accompanied by gangrene or ulceration, a more specific code from the I70.2- series should be used.
