Unsp athscl nonbiol bypass of the extremities, right leg

This code signifies the presence of atherosclerosis, a hardening and narrowing of arteries due to plaque buildup, specifically affecting a non-biological (synthetic) bypass graft located in the right leg. The exact type or extent of the atherosclerosis is not specified in the medical record. This condition can lead to reduced blood flow and potential complications in the bypassed limb.

Use this code when documentation indicates atherosclerosis within a synthetic bypass graft in the right lower extremity, but the specific type (e.g., focal, diffuse, occlusive) is not detailed. This applies to patients who have previously undergone bypass surgery in the right leg using a prosthetic graft and are now presenting with signs or symptoms of graft stenosis or occlusion due to atherosclerotic changes. Documentation should clearly state "atherosclerosis of nonbiological bypass graft, right leg" without further specificity.

• Ensure the documentation specifies "nonbiological" or "synthetic" graft; otherwise, a different code for biological grafts would be appropriate.
• Verify the laterality (right leg) is clearly documented. If the laterality is not specified, an unspecified laterality code should be used.
• If the type of atherosclerosis (e.g., with gangrene, with ulceration) is known, a more specific code within the I70.6 series should be selected.
