About ICD-9-CM 233.9
233.9 is an ICD-9-CM diagnosis code for carcinoma in situ of other and unspecified urinary organs. 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 2 ICD-10-CM codes, such as D09.10 (Carcinoma in situ of unspecified urinary organ) and D09.19 (Carcinoma in situ of other urinary organs). All of these are approximate matches, so review the record to pick the right one.
