About BH040ZZ
BH040ZZ is the ICD-10-PCS code for a plain radiography procedure on the left single mammary duct using a high 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 contrast radiogram of mammary ducts, the ICD-9-CM procedure title it maps to (87.35).
For a different body part, codes include BH030ZZ (right single mammary duct), BH050ZZ (right multiple mammary ducts) and BH060ZZ (left multiple mammary ducts).
The same procedure with a different approach is coded BH041ZZ (low osmolar), BH04YZZ (other contrast) and BH04ZZZ (none).
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.
