Athscl nonbiol bypass of right leg w ulcer oth prt low leg

This code signifies the presence of atherosclerosis affecting a nonbiological (synthetic) bypass graft located in the right leg, specifically complicated by an ulceration on a different part of the lower leg. This indicates a chronic, progressive hardening and narrowing of the synthetic graft, leading to impaired blood flow and subsequent tissue breakdown.

Apply this code when documentation confirms a patient has a history of a nonbiological bypass graft in the right leg that is now stenosed or occluded due to atherosclerosis, and there is an active ulceration on the lower leg (excluding the foot or ankle) attributed to this vascular insufficiency. Supporting documentation should include imaging reports confirming graft atherosclerosis and physician notes detailing the ulcer's location and its relation to the graft's compromised patency.

• Ensure the documentation specifies "nonbiological" graft; biological grafts use different codes.
• Verify the ulceration is on the "other part of lower leg" and not the foot or ankle, as specific codes exist for those locations.
• Sequence this code after any underlying conditions contributing to the atherosclerosis, if applicable, and consider additional codes for the specific type of ulcer.
