About BH01ZZZ
BH01ZZZ is the ICD-10-PCS code for a plain radiography procedure on the left breast using a none 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 Xerography of breast and other mammography, the ICD-9-CM procedure titles it maps to (87.36 and 87.37).
For a different body part, codes include BH00ZZZ (right breast), BH02ZZZ (bilateral breasts), BH03ZZZ (right single mammary duct), BH04ZZZ (left single mammary duct), BH05ZZZ (right multiple mammary ducts) and BH06ZZZ (left multiple mammary ducts).
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.
