About ICD-9-CM 87.01

87.01 is an ICD-9-CM procedure code for Pneumoencephalogram. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 4 ICD-10-PCS codes, such as B020Y0Z (Computerized Tomography (CT Scan) of Brain using Other Contrast, Unenhanced and Enhanced), B020YZZ (Computerized Tomography (CT Scan) of Brain using Other Contrast) and B029Y0Z (Computerized Tomography (CT Scan) of Sella Turcica/Pituitary Gland using Other Contrast, Unenhanced and Enhanced). All of these are approximate matches, so review the record to pick the right one.
