Abnormal level of substances chiefly nonmedicinal as to source in specimens from digestive organs and abdominal cavity.

- R83-R89, Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis
In simple words: Laboratory tests from your digestive system or abdomen show an unusual level of a substance that is not typically used in medicine.
Abnormal level of substances chiefly nonmedicinal as to source in specimens from digestive organs and abdominal cavity. This includes abnormal findings in peritoneal fluid and saliva.It excludes cloudy peritoneal dialysis effluent (R88.0) and fecal abnormalities (R19.5).
Example 1: A patient undergoing a paracentesis has peritoneal fluid analysis that reveals an elevated level of a non-medicinal substance, potentially indicating exposure to an environmental toxin., Saliva testing reveals abnormal levels of heavy metals, such as lead or mercury, in a patient with unexplained neurological symptoms., A patient presents with abdominal pain and discomfort.Analysis of peritoneal fluid obtained during diagnostic laparoscopy reveals unusual levels of industrial chemicals, suggesting a possible environmental exposure.
Documentation should include the specific substance found, the type of specimen collected (peritoneal fluid, saliva, etc.), the method of analysis, and the quantitative result.Correlation with clinical findings and further investigation should also be documented.
