What cardiomyopathy ICD codes can I use?
If you’re looking for cardiomyopathy ICD codes, you’ll be spoiled for choice because there are many of them. Given this, we’ve picked seven examples of cardiomyopathy-related ICD-10 codes so you know how diverse the ICD-10 codes are for this type of condition. Here they are:
- I42.9 - Cardiomyopathy, unspecified: This ICD-10 code is meant to be used on a patient confirmed to have Cardiomyopathy; however, the type of Cardiomyopathy they have is unknown. Only use this if the specific Cardiomyopathy hasn’t been confirmed. If you already confirmed the patient's specific type, please use a more specific ICD-10 code like the one following this item.
- A36.81 - Diphtheritic cardiomyopathy: This ICD-10 code is meant to be used on a patient confirmed to have Diphtheritic Cardiomyopathy. This type of Cardiomyopathy is caused by Diphtheria, a bacterial infection that inflames the mucosa.
- B33.24 - Viral cardiomyopathy: This ICD-10 code is meant to be used on a patient confirmed to have Viral Cardiomyopathy. This type of Cardiomyopathy is caused by viral infections that cause myocarditis.
- I25.5 - Ischemic cardiomyopathy: This ICD-10 code is meant to be used on a patient confirmed to have. This type of Cardiomyopathy is caused by the myocardium sustaining ischemic damage.
- I42.0 - Dilated cardiomyopathy: This ICD-10 code is meant to be used on a patient confirmed to have Dilated Cardiomyopathy. This type of Cardiomyopathy is caused by the enlargement of heart chambers, which, given the enlargement, have difficulty or lose the ability to contract.
- I42.1 - Obstructive hypertrophic cardiomyopathy: This ICD-10 code is meant to be used on a patient confirmed to have Obstructive Hypertrophic Cardiomyopathy. The thickening of the septum between the left and right ventricles causes this type of Cardiomyopathy.
- I42.6 - Alcoholic cardiomyopathy: This ICD-10 code is meant to be used on a patient confirmed to have Alcoholic Cardiomyopathy. This type of Cardiomyopathy is caused by constant and excessive alcohol consumption.
Are these cardiomyopathy ICD codes billable?
Yes. All the aforementioned cardiomyopathy-related ICD-10 codes are valid and billable.
Clinical information about cardiomyopathy:
Cardiomyopathy is a type of heart disease characterized by the heart's enlargement, stiffening, or thickening. When the heart becomes enlarged, stiff, or thick, scar tissue will form, and the presence of scar tissue will prevent the heart from pumping enough blood throughout the body. If this heart disease is left unchecked and untreated, it will ultimately enfeeble the heart until it becomes more susceptible to cardiac arrest or heart failure.
A person with cardiomyopathy will likely have the following symptoms:
- They will start having abnormal heart rates
- They will be prone to palpitations
- They will feel pain in the chest area
- They will have shortness of breath
- They will feel fatigued and become prone to fainting
- In some cases, their legs might become swollen.
Synonyms include:
- Cardiomyopathy co-occurrent with human immunodeficiency virus infection
- Cardiomyopathy due to neuromuscular disorder
- Cirrhotic cardiomyopathy
- Congestive heart failure due to cardiomyopathy
- Cardiomyopathy due to diphtheria
- Dilated cardiomyopathy due to infectious disease
- Dilated cardiomyopathy due to viral myocarditis
- Ischemic congestive cardiomyopathy
- Cardiomyopathy due to connective tissue disease
- Cardiomyopathy due to mucopolysaccharidosis
- Cardiomyopathy caused by drug
- Cardiomyopathy due to viral infection
- Dilated cardiomyopathy secondary to alcohol
Commonly asked questions
Yes. There are a lot more than what was listed above. The seven we showed you are just examples of specific ICD-10 codes for particular types of cardiomyopathy.
Several tests can be conducted to detect/diagnose cardiomyopathy. These include blood tests, cardiac CTs, electrocardiograms, and myocardial biopsies, to mention a few.
It depends on how severe it is and what’s causing it, but treatment may include lifestyle changes that are focused on improving the heart; taking certain medications such as corticosteroids, anti-coagulants, anti-hypertensives, and antiarrhythmics; using blood flow-improving devices; using arrhythmia correctors; going through procedures like a heart transplant, septal myectomy, and ablations.
