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.
