Athscl native arteries of right leg w ulcer oth prt foot

This diagnosis code signifies the presence of atherosclerosis affecting the native arteries of the right leg, specifically complicated by an ulcer located on a part of the foot other than the heel or midfoot. It indicates a chronic, progressive arterial disease leading to impaired blood flow and tissue breakdown in the right lower extremity.

Apply this code when documentation clearly states atherosclerosis of the right leg's native arteries and an ulceration on the right foot, excluding the heel or midfoot. This is typically seen in patients with peripheral artery disease (PAD) presenting with ischemic foot ulcers. Supporting documentation should include a physician's diagnosis of atherosclerosis, the specific location of the ulcer on the right foot, and its direct association with the arterial disease.

• Ensure the documentation specifies "native arteries" and not a bypass graft.
• Verify the exact location of the ulcer on the right foot to differentiate from other ulcer codes (e.g., heel, midfoot).
• Code any associated gangrene or rest pain separately if documented.
