About B546ZZA

B546ZZA is the ICD-10-PCS code for a ultrasonography procedure on the right subclavian vein using a none approach with none (qualifier: guidance). 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 intravascular imaging, other specified vessel(s), the ICD-9-CM procedure title it maps to (00.28).

For a different body part, codes include B543ZZA (right jugular veins), B544ZZA (left jugular veins), B547ZZA (left subclavian vein), B548ZZA (superior vena cava), B549ZZA (inferior vena cava), B54BZZA (right lower extremity veins) and 9 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.
