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 2026, 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.

About the R85 Code Range
The ICD-10 code section R85 covers various abnormal findings in specimens taken from digestive organs and the abdominal cavity. These codes are used when unusual laboratory or cytological results are found but without a specific diagnosis yet established.
This section includes codes such as R85.0 for abnormal enzyme levels in digestive specimens, reflecting issues like elevated pancreatic lipase or low fecal trypsin. For infections or microbiological abnormalities, R85.5 identifies abnormal microbiological findings, including the presence of parasites like Cryptosporidium or Helicobacter pylori in stool samples. Cytological abnormalities in anal smears are detailed in the R85.6 series, covering findings from atypical squamous cells of undetermined significance (ASC-US, R85.610) to high-grade lesions (R85.613) and evidence of malignancy on anal smears (R85.614). Positive tests for high-risk and low-risk human papillomavirus (HPV) DNA in anal specimens are coded as R85.81 and R85.82, respectively. Other abnormal histological and miscellaneous findings from digestive tract specimens fall under R85.7 and R85.8, while R85.9 is used for unspecified abnormal findings. These codes provide detailed options for documenting abnormal test results detected during digestive and abdominal examinations without a definitive diagnosis.
