Athscl type of bypass of the right leg w ulcer oth prt foot

This code describes a specific type of peripheral artery disease involving atherosclerosis within a previously placed bypass graft in the right leg. The atherosclerosis has progressed to cause ulceration on a part of the foot, indicating severe compromise of blood flow. This condition signifies graft failure or significant stenosis leading to tissue breakdown.

Use this code when documentation clearly indicates atherosclerosis affecting a bypass graft in the right leg, specifically with an associated ulcer on the foot. This typically applies to patients with a history of peripheral bypass surgery who present with new or worsening foot ulcers. Supporting documentation would include operative reports detailing the bypass, vascular studies confirming graft atherosclerosis, and wound care notes describing the foot ulcer.

• Ensure the documentation specifies "other type" of bypass graft and "other part of foot" to align with the specificity of this code.
• Do not use this code for native vessel atherosclerosis; a bypass graft must be explicitly documented.
• Sequence this code as a primary diagnosis when the ulceration is the primary reason for the encounter, or as a secondary diagnosis when managing other complications of the atherosclerosis.
