R85.9 — Unspecified abnormal finding in specimens from digestive organs and abdominal cavity
Is R85.9 billable?
Yes, but R85.9 is an unspecified code. R85.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, R85.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting R85.9 — the more specific alternatives are listed below.

How is R85.9 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to R85.9. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Abnormal, abnormality, abnormalities › specimen › digestive organs
Excludes1 — never code together — inherited from R83-R89
The conditions below can never be reported together with R85.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- abnormal findings on antenatal screening of mother (O28.-)
- diagnostic abnormal findings classified elsewhere - see Alphabetical Index
Excludes1 — never code together — inherited from R85
The conditions below can never be reported together with R85.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R85.9, but a patient may have both at the same time. When documentation supports it, R85.9 and the excluded code may both be reported.
