Find comprehensive information on the diagnosis history of NSTEMI (Non-ST-Elevation Myocardial Infarction). Learn about clinical documentation requirements, medical coding guidelines for NSTEMI, and best practices for healthcare professionals. Explore resources covering NSTEMI diagnosis criteria, troponin levels, ECG changes, and risk stratification. Improve your understanding of NSTEMI management, treatment options, and long-term prognosis. This resource offers valuable insights for physicians, nurses, coders, and other healthcare providers involved in the care of patients with NSTEMI.
Also known as
Old myocardial infarction
Previous non-ST elevation myocardial infarction (NSTEMI).
Acute myocardial infarction
Includes codes for current NSTEMI if documented as old.
Personal history of MI
Indicates past myocardial infarction, including NSTEMI.
Chronic ischemic heart disease
May be applicable if NSTEMI led to chronic heart issues.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the NSTEMI currently acute?
Yes
Do NOT code history of NSTEMI. Code the current acute NSTEMI (e.g., I21.4).
No
Is there documented evidence of prior NSTEMI?

Description |
---|
NSTEMI - Non-ST Elevation Myocardial Infarction |
Unstable Angina |
Myocardial Infarction, unspecified |
Insufficient documentation to distinguish between unstable angina and NSTEMI, leading to inaccurate coding (I20.0 vs I21.4).
Incorrect documentation of symptom duration and relief, affecting accurate NSTEMI diagnosis coding and potential DRG assignment.
Misinterpretation or inadequate documentation of troponin levels, crucial for differentiating NSTEMI from unstable angina, impacting coding accuracy.
Patient presents with a history of non-ST-elevation myocardial infarction (NSTEMI). The prior NSTEMI event occurred on [Date of Infarction] and was confirmed by elevated cardiac troponin levels in the setting of ischemic symptoms. Symptoms at the time of the prior event included [List symptoms e.g., chest pain, shortness of breath, nausea, diaphoresis]. Electrocardiogram (ECG) at that time showed [ECG findings, e.g., ST-segment depression, T-wave inversion] without ST-segment elevation. The patient was treated with [Medications and interventions e.g., aspirin, clopidogrel, heparin, nitrates, beta-blockers, coronary angiography with percutaneous coronary intervention (PCI) or medical management]. Current presenting symptoms are [List current symptoms]. Current medications include [List current medications]. Cardiac risk factors include [List risk factors e.g., hypertension, hyperlipidemia, diabetes mellitus, smoking, family history of coronary artery disease]. Physical examination reveals [Record pertinent findings e.g., heart rate, rhythm, blood pressure, lung sounds]. Assessment: History of NSTEMI, currently presenting with [Current symptoms diagnosis, e.g., stable angina, unstable angina, recurrent chest pain]. Plan: [Outline the plan, e.g., Obtain ECG, cardiac biomarkers, assess for recurrent ischemia, adjust medications as needed, consider stress testing, referral to cardiology].
