Also known as
Cardiomyopathy
Covers various types of cardiomyopathy, including nonischemic.
Dilated cardiomyopathy
A common type of NICM characterized by enlarged, weakened heart chambers.
Other cardiomyopathies
Includes less common NICM forms not classified elsewhere.
Alcoholic cardiomyopathy
A specific type of NICM caused by excessive alcohol consumption.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the cardiomyopathy due to a clearly identifiable cause?
Yes
Is it due to alcohol use?
No
Is it hypertrophic?
When to use each related code

| Hypertrophic cardiomyopathy (HCM) |
Using unspecified codes (I42.9) when a more specific NICM subtype is documented leads to inaccurate data and lost revenue.
Failing to capture coexisting conditions like heart failure (I50.x) with NICM impacts risk adjustment and reimbursement.
Insufficient documentation specifying NICM etiology (e.g., dilated, hypertrophic) hinders accurate coding and audit defense.
Patient presents with symptoms suggestive of nonischemic cardiomyopathy (NICM), including [Specific symptoms e.g., dyspnea on exertion, fatigue, peripheral edema, orthopnea, paroxysmal nocturnal dyspnea]. Physical examination reveals [Specific findings e.g., jugular venous distension, S3 gallop, pulmonary rales]. The patient's medical history includes [Relevant medical history e.g., hypertension, diabetes, obesity, family history of cardiomyopathy, alcohol use, chemotherapy exposure, viral infection]. Electrocardiogram (ECG) findings demonstrate [Specific ECG findings e.g., sinus tachycardia, left ventricular hypertrophy, nonspecific ST-T wave changes]. Transthoracic echocardiogram (TTE) reveals [Specific TTE findings e.g., left ventricular dilation, reduced ejection fraction (LVEF), global hypokinesis, regional wall motion abnormalities, diastolic dysfunction]. Cardiac biomarkers [e.g., troponin] are [elevated/within normal limits]. Coronary artery disease (CAD) has been ruled out by [Method of exclusion e.g., negative coronary angiography, normal coronary CT angiography]. The differential diagnosis includes other forms of cardiomyopathy such as hypertrophic cardiomyopathy (HCM) and restrictive cardiomyopathy (RCM), as well as other causes of heart failure. Based on the clinical presentation, diagnostic workup, and exclusion of other etiologies, the diagnosis of nonischemic cardiomyopathy is established. The patient's current LVEF is [Specific LVEF percentage]. Treatment plan includes [Specific treatment plan e.g., guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) including ACE inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRAs), sodium-glucose cotransporter-2 (SGLT2) inhibitors, diuretics as needed for fluid management, cardiac rehabilitation, consideration for implantable cardioverter-defibrillator (ICD) placement for primary prevention of sudden cardiac death (SCD) based on current guidelines]. Patient education provided regarding lifestyle modifications including sodium restriction, fluid restriction, and regular exercise. Follow-up scheduled in [Timeframe] to assess response to therapy and adjust treatment as needed. ICD-10 code I42.0 dilated cardiomyopathy is assigned, pending further specification as needed.
