About B50B1ZZ

B50B1ZZ is the ICD-10-PCS code for a plain radiography procedure on the right lower extremity veins using a low osmolar approach with none (qualifier: none). In ICD-10-PCS, plain radiography means planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate.

In plain terms, this corresponds to phlebography of femoral and other lower extremity veins using contrast material, the ICD-9-CM procedure title it maps to (88.66).

For a different body part, codes include B5001ZZ (epidural veins), B5011ZZ (cerebral and cerebellar veins), B5021ZZ (intracranial sinuses), B5031ZZ (right jugular veins), B5041ZZ (left jugular veins), B5051ZZ (bilateral jugular veins) and 21 more.

The same procedure with a different approach is coded B50B0ZZ (high osmolar) and B50BYZZ (other contrast).

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.
