About BQ49ZZZ
BQ49ZZZ is the ICD-10-PCS code for a ultrasonography procedure on the bilateral knees using a none approach with none (qualifier: none). 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 other diagnostic ultrasound, the ICD-9-CM procedure title it maps to (88.79).
For a different body part, codes include BQ40ZZZ (right hip), BQ41ZZZ (left hip), BQ42ZZZ (bilateral hips), BQ47ZZZ (right knee) and BQ48ZZZ (left knee).
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.
