About B040ZZZ
B040ZZZ is the ICD-10-PCS code for a ultrasonography procedure on the brain 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 diagnostic ultrasound of head and neck, the ICD-9-CM procedure title it maps to (88.71).
For a different body part, codes include B04BZZZ (spinal cord).
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.
