CARDIOMYOPATHY

Increased Specificity 

When documenting cardiomyopathy, include the following, where appropriate: 

1. Type e.g. Dilated/congestive, obstructive or nonobstructive hypertrophic, etc. 

2. Location e.g. Endocarditis, right ventricle, etc. 

3. Cause e.g. Congenital, alcohol, etc. 

 List cardiomyopathy seen in other diseases such as gout, amyloidosis, etc.

ICD-10 Code Examples

I42.0 Dilated cardiomyopathy 

I42.1 Obstructive hypertrophic cardiomyopathy 

I42.3 Endomyocardial (eosinophilic) disease

HEART VALVE DISEASE

Increased Specificity 

ICD-10 assumes heart valve diseases are rheumatic; if this is not the case, notate otherwise. 

When documenting heart valve disease, include the following:

1. Cause e.g. Rheumatic or non-rheumatic 

2. Type e.g. Prolapse, insufficiency, regurgitation, incompetence, stenosis, etc. 

3. Location e.g. Mitral valve, aortic valve, etc.

ICD-10 Code Examples

I06.2 Rheumatic aortic stenosis with insufficiency 

I34.1 Nonrheumatic mitral (valve) prolapse

ARRYTHMIAS/DYSRHYTHMIA

Increased Specificity

When documenting arrhythmias, include the following: 

1. Location e.g. Atrial, ventricular, supraventricular, etc. 

2. Rhythm name e.g. Flutter, fibrillation, type 1 atrial flutter, long QT syndrome, sick sinus syndrome, etc. 

3. Acuity e.g. Acute, chronic, etc. 

4. Cause e.g., Hyperkalemia, hypertension, alcohol consumption, digoxin, amiodarone, verapamil HCl

ICD-10 Code Examples

I48.2 Chronic atrial fibrillation 

I49.01 Ventricular fibrillation
