Athscl nonaut bio bypass of right leg w ulcer oth prt foot

This code signifies the presence of atherosclerosis affecting a non-autologous biological bypass graft located in the right leg, specifically complicated by an ulceration on a part of the foot other than the heel or midfoot. This indicates a failure or compromise of the graft due to plaque buildup, leading to ischemic tissue damage in the foot.

Use this code when documentation clearly states atherosclerosis of a non-autologous biological bypass graft in the right leg, with a resulting ulceration on the foot (excluding heel/midfoot). This typically applies to patients who have undergone bypass surgery using a synthetic or donor vessel graft and are now experiencing graft failure with ischemic foot ulceration.

• Ensure the documentation specifies "non-autologous biological" graft; differentiate from autologous (native vein) grafts.
• Verify the laterality (right leg) and the specific location of the ulceration on the foot.
• Sequence this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment.
