Atherosclerosis of nonautologous biological bypass graft(s) of other extremity with ulceration
Clinical Classification Guidelines
Use Additional Code
- code to identify severity of ulcer (L98.49)
Medical Intelligence & Overview
Atherosclerosis of nonautologous biological bypass grafts with ulceration (ICD-10 code I70.55) refers to the buildup of fatty deposits inside a graft used to bypass a blocked artery in the extremities, particularly when this is complicated by ulcer formation. This condition can affect individuals who have had surgical procedures to improve blood flow to their limbs, often due to peripheral artery disease. The presence of ulcers indicates tissue damage and compromised blood supply, posing risks for infection and further complications.
Causes & Symptoms
Clinical Causes: Progressive buildup of fatty deposits (atherosclerosis) within the graft material Poor blood circulation leading to plaque formation in the graft Underlying peripheral artery disease advancing over time Inadequate blood flow restoration after bypass surgery Infection or inflammation at the graft site Trauma or injury to the graft or surrounding tissues
Key Symptoms: Ulcers or open sores on the extremities, often near the graft site Pain or tenderness in the affected limb, especially during activity Coolness or discoloration of the skin distal to the graft Weak or absent pulses in the limb Swelling or redness around the affected area Skin that appears shiny, thin, or at risk of breakdown
Diagnostic & Treatment
Diagnosis Path: Diagnosis usually involves a combination of clinical evaluation and imaging studies. Healthcare professionals may perform:
Treatment Protocols: Management typically aims to restore adequate blood flow, promote ulcer healing, and prevent further complications. Approaches may include:
