Athscl nonbiol bypass of the extrm w intrmt claud, bi legs

This code describes the hardening and narrowing of a synthetic or artificial bypass graft in both lower extremities, leading to pain, cramping, or tiredness in the legs that occurs with exercise and is relieved by rest. This condition is a form of peripheral artery disease affecting previously implanted nonbiological grafts.

Use this code when documentation specifies atherosclerosis affecting nonbiological bypass grafts in both legs, and the patient experiences intermittent claudication as a symptom. This code requires clear documentation of the graft type (nonbiological), the affected extremities (bilateral legs), and the presence of claudication.

• Ensure the documentation specifies "nonbiological" bypass graft; do not use for autologous or biological grafts.
• Verify that claudication is explicitly documented as "intermittent" and affects "bilateral legs."
• Consider additional codes for underlying atherosclerosis of native vessels if also present and documented.
