In simple words: This code describes a buildup of plaque in the arteries that have been bypassed during a heart surgery, but without chest pain.It helps doctors track the condition of the bypass grafts and monitor for potential future problems.

This ICD-10-CM code classifies atherosclerosis affecting coronary artery bypass grafts, without the presence of angina pectoris.It indicates the presence of atherosclerotic plaque buildup in the grafted vessels but does not include cases where the patient experiences chest pain (angina).Additional codes may be necessary to specify the type of plaque (I25.83 for lipid-rich plaque or I25.84 for calcified lesion) and associated factors like tobacco use.

Example 1: A 65-year-old male patient, three years post coronary artery bypass graft (CABG) surgery, presents for a routine checkup.Cardiac catheterization reveals mild atherosclerosis in one of the bypass grafts, but the patient reports no chest pain or other symptoms.Code I25.810 is assigned., A 70-year-old female patient with a history of CABG undergoes a follow-up angiogram showing significant atherosclerosis in multiple bypass grafts. Despite the severity of the atherosclerosis, the patient remains asymptomatic.Code I25.810 is assigned, along with additional codes to specify the type of plaque (e.g., I25.83, I25.84) and any contributing factors (e.g., tobacco use)., A 58-year-old patient, five years post-CABG, is admitted with acute coronary syndrome.Angiography reveals significant atherosclerosis in a native coronary artery and a bypass graft. The patient is experiencing chest pain. Code I25.810 is used in addition to other codes representing the angina pectoris and location of the atherosclerosis.

Complete medical history, including previous cardiac procedures and current symptoms.Results of cardiac catheterization, angiography, or other relevant diagnostic imaging.Physician's assessment and documentation of the absence of angina pectoris.

** This code should not be used if the patient is experiencing angina pectoris.In such cases, the appropriate code for atherosclerosis of coronary artery bypass grafts with angina should be used.Always refer to the complete ICD-10-CM coding guidelines for clarification and specific instructions.
