About B244ZZ4
B244ZZ4 is the ICD-10-PCS code for a ultrasonography procedure on the right heart using a none approach with none (qualifier: transesophageal). In ICD-10-PCS, ultrasonography means real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves.
In plain terms, this corresponds to diagnostic ultrasound of heart, the ICD-9-CM procedure title it maps to (88.72).
For a different body part, codes include B240ZZ4 (coronary artery, single), B241ZZ4 (coronary arteries, multiple), B245ZZ4 (left heart), B246ZZ4 (heart, right and left), B24BZZ4 (heart with aorta), B24CZZ4 (pericardium) and 1 more.
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
