About ICD-9-CM 602.3

602.3 is an ICD-9-CM diagnosis code for dysplasia of prostate. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 4 ICD-10-CM codes, such as N42.30 (Unspecified dysplasia of prostate), N42.31 (Prostatic intraepithelial neoplasia) and N42.32 (Atypical small acinar proliferation of prostate). All of these are approximate matches, so review the record to pick the right one.
