About R89

R89 is the ICD-10-CM diagnosis code for abnormal findings in specimens from other organs, systems and tissues. It belongs to block R83-R89 (abnormal findings on examination of other body fluids, substances and tissues, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R89.0 (tissues), R89.1 (tissues), R89.2 (tissues), R89.3 (tissues), R89.4 (tissues), R89.5 (tissues), R89.6 (tissues), R89.7 (tissues) and 2 more.

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