2025 ICD-10-CM code I70.709
(Active) Effective Date: N/A Diseases of the circulatory system - Diseases of arteries, arterioles and capillaries IX Feed
Unspecified atherosclerosis of other type of bypass graft(s) of the extremities, unspecified extremity.
Medical necessity for interventions related to this diagnosis depends on the severity of the atherosclerosis and its impact on the patient's health and quality of life. Factors to consider include the presence of claudication, rest pain, ulceration, or gangrene. The medical record must clearly document the clinical rationale for any procedures or treatments performed.
Diagnosis and management of atherosclerosis in bypass grafts falls under the purview of vascular specialists, cardiologists, or general surgeons, depending on the specific clinical context and the expertise available.
In simple words: This refers to hardening and narrowing of arteries in a bypass graft of an extremity, where the exact location and graft type aren't specified.
Unspecified atherosclerosis of other type of bypass graft(s) of the extremities, unspecified extremity. This code signifies the presence of atherosclerosis in a bypass graft in an extremity, where the specific type of graft and the affected extremity are not specified.
Example 1: A patient presents with leg pain and reduced blood flow following a bypass graft procedure using an unspecified type of graft. Angiography confirms the presence of atherosclerosis within the graft. The I70.709 code is used due to the lack of further specificity about the graft type or extremity., A patient with a history of peripheral artery disease and a previous lower extremity bypass graft procedure of an unspecified nature experiences recurring symptoms. Diagnostic imaging shows atherosclerosis in the graft, but the type of graft and laterality are unknown, making I70.709 the appropriate code., During a follow-up examination for a patient who has undergone a bypass graft surgery in an unspecified extremity with an unknown graft type, the physician notes signs of reduced circulation. Further tests reveal atherosclerotic changes within the graft. As the affected extremity and type of graft are not documented, I70.709 is applied.
Documentation should include details of the patient's symptoms, medical history (including prior bypass surgery), diagnostic findings (e.g., angiography, ultrasound), and the physician's assessment. If possible, the type of bypass graft and the affected extremity should be specified for more accurate coding. If the information is not available, this should be explicitly stated in the documentation.
