About R85
R85 is the ICD-10-CM diagnosis code for abnormal findings in specimens from digestive organs and abdominal cavity. 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: R85.0 (cavity), R85.1 (cavity), R85.2 (cavity), R85.3 (cavity), R85.4 (cavity), R85.5 (cavity), R85.6 (cavity), R85.7 (cavity) and 2 more.
Don't report R85 together with the conditions in its Excludes1 note: cloudy peritoneal dialysis effluent (R88.0) and fecal abnormalities (R19.5).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
