Reportability: Is positive urine cytology (ex: malignant cells interpreted as carcinoma) by itself reportable? If so, is the case coded to bladder by default or is is coded to C689, urinary system, NOS?
Urine cytology positive for malignancy is reportable. Code the primary site to C689 in the absence of any other information.
However, if a subsequent biopsy of a urinary site is negative, do not report the case.
For 2013 diagnoses and forward, report these cases when they are encountered. Do not implement new/additional casefinding methods to capture these cases.
As always, do not report cytology cases with ambiguous terminology.
