Understanding Old Myocardial Infarction diagnosis, documentation, and medical coding? Find information on healed MI, previous MI, history of MI, acute MI vs. old MI, myocardial infarction diagnosis code, ICD-10 code for old MI, I25.2, and clinical indicators of a prior MI for accurate healthcare records and medical coding compliance. Learn about recognizing old myocardial infarction on ECG, EKG interpretation for old MI, and relevant cardiac markers for past MI.
Also known as
Old myocardial infarction
Identifies a past heart attack.
Acute myocardial infarction
Classifies current heart attacks by location.
Atherosclerotic heart disease
Indicates coronary artery disease, a common cause of heart attacks.
Other forms of chronic ischemic heart disease
Includes related heart conditions due to reduced blood flow.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the MI documented as acute?
Yes
Do NOT code as old MI. Code as acute MI (I21.x).
No
Is the MI type specified?
When to use each related code

Insufficient documentation to distinguish between acute MI, healed MI, or age-indeterminate MI impacting code selection (I25.2 vs. I25.9).
Incorrect sequencing of acute MI with subsequent complications or chronic conditions like heart failure, affecting reimbursement.
Lack of physician queries to clarify ambiguous documentation of old MI, leading to coding and DRG assignment errors.
Patient presents with a history of old myocardial infarction. The date of the original MI is documented as [Date of MI] and was confirmed by [Method of Confirmation, e.g., elevated cardiac enzymes, EKG changes]. Current presenting symptoms include [List current symptoms, e.g., atypical chest pain, dyspnea on exertion, fatigue]. The patient denies [List pertinent negatives, e.g., acute chest pain, diaphoresis, nausea]. Physical examination reveals [Document relevant physical exam findings, e.g., regular heart rate and rhythm, no murmurs, clear lung sounds]. Electrocardiogram shows [EKG findings consistent with old MI, e.g., Q waves in [Leads], no ST-segment elevations]. Current medications include [List current medications, e.g., aspirin, beta-blocker, ACE inhibitor, statin]. Assessment: Old myocardial infarction, stable angina (if applicable), [Other relevant diagnoses]. Plan: Continue current medications. Patient education provided on symptom management, importance of medication adherence, and risk factor modification including diet, exercise, and smoking cessation. Follow-up scheduled in [Timeframe] to reassess symptoms and optimize medical management. ICD-10 code: I25.2. Medical necessity for continued medication management and follow-up care established.
