Question: Can you help me find the correct code for a 6-lead ECG home visit? My cardiologist performs home visits for most of her homebound patients. She carries a portable ECG device with her at all times. She performed the test and interpretation with report and strip, as documented in the patient’s chart. Illinois Subscriber Answer: What your provider is most likely using is what’s called a KardiaMobile device. This device is the first ever FDA-cleared mobile, 6-lead ECG. The patient’s ECG is recorded and then available to be downloaded and interpreted. The advice is to bill 99091 (Collection and interpretation of physiologic data (eg, ECG, blood pressure, glucose monitoring) digitally stored and/or transmitted by the patient and/or caregiver to the physician or other qualified health care professional, qualified by education, training, licensure/regulation (when applicable) requiring a minimum of 30 minutes of time, each 30 days) for this procedure.
