2025 ICD-10-CM code I24.0
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Circulatory System Diseases - Ischemic heart diseases Diseases of the circulatory system (I00-I99) Feed
Acute coronary thrombosis without myocardial infarction.
Modifiers may apply depending on the circumstances, such as the place of service and the use of anesthesia. Always refer to the latest CPT and HCPCS guidelines for modifier usage.
Medical necessity is established by the presence of symptoms suggestive of myocardial ischemia (chest pain, shortness of breath, diaphoresis), evidence of coronary artery obstruction via coronary angiography, and absence of myocardial necrosis (elevated cardiac biomarkers).
The clinical responsibility falls on a cardiologist or other physician specializing in cardiovascular disease. This includes diagnosis, monitoring, and management of the patient's condition, and may involve medication management, lifestyle modifications, and possible interventional procedures if the blockage becomes critical.
In simple words: A blood clot has blocked a blood vessel in the heart, but the heart muscle hasn't been harmed.
This code signifies acute coronary thrombosis (blood clot in a coronary artery) that does not result in myocardial infarction (heart muscle damage).It indicates a blockage in a coronary artery, but the heart muscle has not been irreversibly damaged.
Example 1: A 65-year-old male presents to the emergency department with chest pain.ECG and cardiac enzymes are negative, but angiography reveals a significant coronary artery blockage that does not cause ST elevation. I24.0 is assigned., A 72-year-old female with a history of coronary artery disease experiences transient chest discomfort.Cardiac biomarkers are normal, and angiography demonstrates a non-occlusive thrombus in a coronary artery. I24.0 is used., A 58-year-old male is admitted for observation after a coronary angiogram reveals a small, non-obstructive clot in a coronary artery, causing no myocardial damage.The patient is stable with no cardiac enzyme elevations. I24.0 is the appropriate code.
Detailed history and physical examination, ECG findings (preferably serial ECGs demonstrating resolution), cardiac enzyme levels (CK-MB, troponin), and coronary angiography results showing the presence and location of the thrombus and its impact on coronary blood flow.Absence of myocardial necrosis must be documented.
** This code should only be applied when coronary thrombosis is confirmed via angiography or other suitable imaging, and no evidence of myocardial damage is found.The clinical scenario needs to align with the definition of the code.The absence of symptoms alone does not warrant the use of this code. The absence of elevated cardiac biomarkers is key.
