ICD-10 Code for Abnormal Echocardiogram

An echocardiogram provides valuable insights into structural abnormalities, valve disorders, and blood flow. When an echocardiogram yields abnormal results, the findings are translated into medical codes for documentation and billing purposes. It is here that ICD-10 codes are used.

This article examines the application of the ICD-10 codes in managing abnormal echocardiogram findings and the appropriate use of general codes.

What is ICD-10-CM 10

Maintained by WHO, ICD-10 is the International Classification of Diseases, 10th Revision, a global system that classifies and codes diseases, injuries, and causes of death. It tracks health trends, analyses mortality data, and supports clinical care.

Healthcare providers use the ICD-10 to code and classify every disease, symptom, and injury. It is then submitted to the insurance claims.

Importance of ICD

ICD-10-CM has approximately 70,000 codes. These codes, when stored in the electronic health record, are sent to insurers.

Insurers pay the doctor to diagnose the patient.

Health authorities, such as the CDC, use this code to help track the number of cases of the disease that occurred in that year.

ICD classification

In the United States, the ICD is classified into the following

  • The International Classification of Diseases (ICD) is a standardized system to code causes of death and data from death certificates.
  • The International Classification of Diseases Clinical Modification (ICD-CM) codes diseases and medical conditions data.
  • The International Classification of Functioning Disability and Health (ICF) is related to functioning and disability.

Interpreting the code 

The first three characters, a letter, and two numbers, represent the disease or the health condition.

After the first three characters is a period.

The next three numbers describe the cause of the disease, how severe it is, and where it is in the body

Each ICD code starts with a capital letter from A to Z, which categorizes the disease

A: Infectious and parasitic diseases

B: Infectious and parasitic diseases

C: Cancer

D: Neoplasm, blood and blood-forming organs

E: Endocrine, nutritional, or metabolic

F: Mental and behavioral disorders

G: Nervous system

H: Eyes, ears, nose, and throat

I: Circulatory system

J: Respiratory system

K: Digestive system

L: SkinM: Musculoskeletal system

N: Genitourinary system

O: Pregnancy and childbirth

P: Perinatal conditions

Q: Congenital and chromosomal abnormalities

R: Abnormal clinical and lab findings

S: Injury, poisoning, and external causes

T: Injury, poisoning, and external causes

U: Used for emergency

V: External causes of morbidity

W: External causes of morbidity

X: External causes of morbidity

Y: External causes of morbidity

Z: Factors influencing health status and contact with health services

Additional numbers and letters help to specify and characterize the condition. For example, E10.9 represents type 1 diabetes, and E11.9 represents type 2 diabetes.

Specifying the code

A normal echo code does not have a single ICD-10 code. The reason for performing the echocardiogram, along with the clinical context, helps determine the code.

If the echocardiogram was for screening heart disease, ICD-10 code Z13.6 may be appropriate. However, if an abnormal finding is present, R93.1 or R94.31 could be used, depending on the specific finding.

Abnormalities in an echocardiogram

An echocardiogram is abnormal if it shows

  • Dilation or hypertrophy of the atria or ventricles
  • Narrowing, stenosis, regurgitation, leakage, or prolapse of the walls of the heart
  • Reduced ejection fraction
  • Which usually occurs after a MI 
  • Accumulation of fluid in the sac around the heart
  • Septal defects in the heart since birth

General code: ICD-10 code R93.1

R93.1 indicates abnormal findings of diagnostic imaging of the heart and coronary circulation

It is appropriate when

  • The echocardiogram shows abnormal results, but no definite diagnosis
  • The finding is accidental, or the clinical significance is still being evaluated
  • The patient is being investigated, and the echo result is the first abnormal finding

For example, a patient experiences mild fatigue and undergoes an echocardiogram, which shows regurgitation without structural abnormalities. The diagnosis is not yet confirmed; it is still being evaluated. Therefore, R93.1 is the code used to document it.

Specific code ICD-10

The specific codes under I00-I99 are for diseases of the circulatory system. Some examples are

*denotes acuity or type of condition

Table 1
Condition

Cardiomegaly I51.7 Enlarged heart chambers on echocardiogram
Heart failure with reduced ejection fraction I50.2x* Ejection fraction <40% systolic dysfunction
Heart failure with preserved ejection fraction I50.3x* Diastolic dysfunction
Regurgitation I34.0 Mitral valve leak on Colour Doppler
Aortic stenosis I35.0 Thickened or calcified aortic valve
Dilated cardiomyopathy I42.0 Left ventricular wall thickening with preserved ejection fraction
Ischaemic heart disease I25.x Regional wall motion abnormalities

Conclusion

The correct ICD code for echocardiogram findings is essential for accurate documentation, reimbursement, and continuity of care. At Gauze, we understand the nuances of the codes, like, the code R93.1 is for unspecified abnormalities, and codes from I00 to I99 are specific to the circulatory system.

The ICD-10-CM is used for reporting in all healthcare settings. It is a standardized classification of diagnosis codes that represent diseases, health-related problems, abnormal findings, signs and symptoms, external causes of injuries, and social circumstances.

The latest version of the International Classification of Diseases is ICD-11. It came into effect on January 1, 2022, and serves as a global health standard for health information, developed by the WHO.

The international version of ICD-10 is used in over 100 countries for reporting causes of death and compiling statistics.

They help code and classify medical diagnoses.

The ICD-10-CM code R93.1 is used for an abnormal echocardiogram. This code falls under the category of abnormal findings and diagnostic imaging. It is used when an abnormality is revealed, but the specific diagnosis has not yet been established.
