2025 ICD-10-CM code I25.82
(Active) Effective Date: N/A Diseases of the circulatory system - Chronic ischemic heart disease IX Feed
Chronic total occlusion of a coronary artery.
Medical necessity for interventions related to chronic total occlusion of a coronary artery must be supported by documentation demonstrating the impact of the occlusion on the patient's health, such as angina, reduced heart function, or other symptoms. The chosen treatment approach should be justified based on the patient's overall clinical picture and established guidelines.
Diagnosis and management of patients with chronic total occlusion of coronary artery often falls under the purview of cardiologists and related specialists. They are responsible for assessing the patient's condition, determining the best course of treatment, and monitoring the patient's progress.
In simple words: This code signifies a long-term blockage of a coronary artery, the blood vessel supplying the heart muscle.
Complete occlusion of a coronary artery. Total occlusion of a coronary artery.
Example 1: A 65-year-old male patient presents with a history of angina and undergoes an angiogram, which reveals a chronic total occlusion of the left anterior descending artery., A 50-year-old female with a history of diabetes and hypertension experiences recurring chest pain. Diagnostic imaging confirms a chronic total occlusion of the right coronary artery., A 70-year-old patient with prior coronary artery bypass surgery is found to have a chronic total occlusion in a native coronary artery during a follow-up angiogram.
Documentation should include details of the diagnostic studies confirming the occlusion (e.g., angiography, cardiac CT), the location of the occlusion, the presence or absence of symptoms, and any associated conditions such as angina, heart failure, or prior interventions.
** This code represents a chronic condition and should not be used for acute occlusions. Always code the underlying coronary atherosclerosis first, followed by I25.82.
