About D41

D41 is the ICD-10-CM diagnosis code for neoplasm of uncertain behavior of urinary organs. It belongs to block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D41.0 (kidney), D41.1 (pelvis), D41.2 (ureter), D41.3 (urethra), D41.4 (bladder), D41.8 (organs) and D41.9 (organ).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
