Abnormal EKG ICD-10-CM Codes

What ICD-10 code is used for abnormal EKG? 

An electrocardiogram (EKG or ECG) is a test that records the electrical activity of the heart to help detect any potential problems. It’s usually performed when a patient experiences symptoms like chest pain, dizziness, palpitations, or shortness of breath. Doctors may also order it as part of a routine checkup, especially for people with a history of heart issues.

When an EKG is labeled as abnormal, it means the results show patterns that differ from what’s considered typical, such as irregular rhythms, unusual wave patterns, or timing issues. These abnormalities can point to conditions like arrhythmias, signs of a past heart attack, or other underlying cardiac problems.

To document this, healthcare providers use the ICD-10 code R94.31: Abnormal electrocardiogram [ECG] [EKG]. This code falls under the R90-R94 category abnormal findings on diagnostic imaging and in function studies, specifically under R94 which refers to abnormal results of function studies. It’s important to note that this code excludes certain specific conditions. Long QT syndrome, for example, is not included in Type 1 and is instead coded as I45.81. Using the right code helps ensure accurate diagnosis, treatment planning, and medical recordkeeping.

Clinical information

• An abnormal EKG reading can mean several things. It may be a normal variation of one's heart rhythm or a medical issue one has to be concerned with, like a heart attack, cardiomyopathy, and arrhythmia.  
• More specifically, if a practitioner detects an abnormal result, the patient may have heart rate/rhythm abnormalities, heart attack, electrolyte imbalances, defects/abnormalities in the heart, high blood pressure, or any heart medication side effects. 
• Patients are encouraged to get an EKG reading if they feel chest pain, rapid pulse, shortness of breath, heart palpitations, or are diagnosed with heart disease. 
• Treatment for those whose EKG has an abnormal result may vary depending on the cause. But some common treatments include a pacemaker, medication, cardiac catheterization, and fluids. 

Synonyms include

• Abnormal finding on EKG
• Electrocardiogram abnormal
• Inverted T wave
• T wave inversion in EKG
