2025 ICD-10-CM code I21.0
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Ischemic heart diseases - Acute myocardial infarction Diseases of the circulatory system (I00-I99) Feed
ST-segment elevation myocardial infarction (STEMI) of the anterior wall.
Modifiers may apply depending on the circumstances, such as the place of service or the type of procedure performed.Consult the official modifier guidelines for details.
Medical necessity for coding I21.0 is established by the presence of clinical findings consistent with STEMI, including characteristic chest pain, ECG changes, and elevated cardiac biomarkers.The treatment rendered should be medically appropriate given the patient's condition and in accordance with established clinical guidelines.
The clinical responsibility includes diagnosing the STEMI through history taking, physical examination, ECG interpretation, and cardiac biomarker analysis.Treatment may involve administering thrombolytic therapy (e.g., tPA), performing percutaneous coronary intervention (PCI), or providing supportive care. Ongoing monitoring and post-acute management are crucial.
In simple words: This code describes a serious type of heart attack where a major artery in the heart is completely blocked, causing damage to the front part of the heart muscle. This is diagnosed with an EKG and blood tests.
This code signifies an acute transmural myocardial infarction (heart attack) specifically affecting the anterior wall of the left ventricle.It's characterized by ST-segment elevation on an electrocardiogram (ECG), indicating complete blockage of a coronary artery. The diagnosis requires confirmation through ECG findings, cardiac biomarkers (such as troponin), and clinical presentation.
Example 1: A 65-year-old male presents to the emergency department with crushing chest pain radiating to his left arm.ECG reveals ST-segment elevation in the anterior leads. Cardiac biomarkers are elevated, confirming the diagnosis of STEMI of the anterior wall. The patient undergoes immediate PCI., A 72-year-old female experiences sudden onset of shortness of breath and chest pain.ECG shows ST-segment elevation in the anterior leads, consistent with STEMI. Due to contraindications for PCI, thrombolytic therapy is administered., A 58-year-old male with a history of hypertension presents to the hospital with chest discomfort.His ECG demonstrates ST-segment elevation in leads V1-V4.Cardiac enzyme levels are elevated, and he is diagnosed with a STEMI of the anterior wall. He undergoes coronary angiography followed by PCI.
Comprehensive documentation is needed, including the patient's history (risk factors, symptoms), physical examination findings, ECG reports demonstrating ST-segment elevation, cardiac biomarker results (troponin levels), details of any interventions (PCI, thrombolytic therapy), and post-procedure course.
** Accurate coding necessitates a thorough review of the patient's clinical record, including ECG interpretation and cardiac biomarker analysis.Consider the potential for complications and their appropriate coding.
