Abnormal findings in specimens from digestive organs and abdominal cavity (R85) ICD-10-CM
The R85 code range covers abnormal findings in specimens from digestive organs and abdominal cavity with 25 ICD-10-CM diagnosis codes. 21 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- abnormal findings in peritoneal fluid
- abnormal findings in saliva
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Cytologic Evidence of Malignancy on Anal Papanicolaou Smear

About the R85 Code Range
These codes describe abnormal findings in samples from digestive organs or the abdominal cavity when no diagnosis is given.
The subdivisions separate findings by what was examined, including enzymes, hormones, drugs, other substances, immune responses, microbes, cells, and tissue. R85.61 further separates findings from anal cell smears by the reported cell changes or whether the smear was satisfactory. R85.69 covers cell findings from other digestive organs and the abdominal cavity. Under R85.8, positive anal HPV DNA tests split by high or low risk. R85.9 identifies an unspecified abnormal finding.
