About BP4GZZ1
BP4GZZ1 is the ICD-10-PCS code for a ultrasonography procedure on the right elbow using a none approach with none (qualifier: densitometry). 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 bone mineral density studies, the ICD-9-CM procedure title it maps to (88.98).
For a different body part, codes include BP48ZZ1 (right shoulder), BP49ZZ1 (left shoulder), BP4HZZ1 (left elbow), BP4LZZ1 (right wrist), BP4MZZ1 (left wrist), BP4NZZ1 (right hand) 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.
