About BF4CZZZ
BF4CZZZ is the ICD-10-PCS code for a ultrasonography procedure on the hepatobiliary system, all 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 digestive system, the ICD-9-CM procedure title it maps to (88.74).
For a different body part, codes include BF40ZZZ (bile ducts), BF42ZZZ (gallbladder), BF43ZZZ (gallbladder and bile ducts), BF45ZZZ (liver), BF46ZZZ (liver and spleen) and BF47ZZZ (pancreas).
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.
