How is R85.611 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to R85.611. They show the wording a clinician may have documented, which often differs from the Tabular description.
- ASC-H › anus (atypical squamous cells cannot exclude high grade squamous intraepithelial lesion on cytologic smear)
- Abnormal, abnormality, abnormalities › cytology › anus › atypical squamous cells cannot exclude high grade squamous intraepithelial lesion
- Abnormal, abnormality, abnormalities › Papanicolaou › anus › atypical squamous cells cannot exclude high grade squamous intraepithelial lesion
Excludes1 — never code together — inherited from R83-R89
The conditions below can never be reported together with R85.611 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

Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R85.611, but a patient may have both at the same time. When documentation supports it, R85.611 and the excluded code may both be reported.
