Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R99), in the block Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis (R83-R89).

R85 — Abnormal findings in specimens from digestive organs and abdominal cavity

Non-billable headerICD-10-CM

R85 is a non-billable header ICD-10-CM code for abnormal findings in specimens from digestive organs and abdominal cavity. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

cloudy peritoneal dialysis effluent (R88.0)
fecal abnormalities (R19.5)

Includes

Conditions this code covers.

abnormal findings in peritoneal fluid
abnormal findings in saliva

Other codes that can never be billed with R85

These codes carry an Excludes1 note pointing at R85. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R85 alone.

R85.61Abnormal cytologic smear of anus
K62.82Dysplasia of anus

Risk adjustment

R85 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead R85

10 child codes. Green means billable.
