About D49.5

D49.5 is the ICD-10-CM diagnosis code for neoplasm of unspecified behavior of other genitourinary organs. It belongs to category D49 (neoplasms of unspecified behavior), block D49 (neoplasms of unspecified behavior) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within D49, choose D49.5 (other genitourinary organs) only when documentation doesn't support a more specific option: digestive system (D49.0), respiratory system (D49.1), bone, soft tissue, and skin (D49.2), breast (D49.3), bladder (D49.4), brain (D49.6), endocrine glands and other parts of nervous system (D49.7), other specified sites (D49.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: D49.51 (kidney) and D49.59 (organ).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
