About BL40ZZZ
BL40ZZZ is the ICD-10-PCS code for a ultrasonography procedure on the connective tissue, upper extremity 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 BL41ZZZ (connective tissue, lower extremity), BL42ZZZ (tendons, upper extremity) and BL43ZZZ (tendons, lower extremity).
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.
