R85.6Abnormal cytological findings in specimens from digestive organs and abdominal cavity

R85.6 is the ICD-10-CM diagnosis code for abnormal cytological findings in specimens from digestive organs and abdominal cavity. It belongs to category R85 (abnormal findings in specimens from digestive organs and abdominal cavity), 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 2 subcodes must be used instead.

Within R85 (abnormal findings in specimens from digestive organs and abdominal cavity), R85.6 is specifically for abnormal cytological findings in specimens from digestive organs and abdominal cavity. Related codes cover abnormal level of enzymes in specimens from digestive organs and abdominal cavity (R85.0), abnormal level of hormones in specimens from digestive organs and abdominal cavity (R85.1), abnormal level of other drugs, medicaments and biological substances in specimens from digestive organs and abdominal cavity (R85.2), abnormal level of substances chiefly nonmedicinal as to source in specimens from digestive organs and abdominal cavity (R85.3), abnormal immunological findings in specimens from digestive organs and abdominal cavity (R85.4), abnormal microbiological findings in specimens from digestive organs and abdominal cavity (R85.5), abnormal histological findings in specimens from digestive organs and abdominal cavity (R85.7), other abnormal findings in specimens from digestive organs and abdominal cavity (R85.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: R85.61 (anus) and R85.69 (cavity).

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