R92 — Abnormal and inconclusive findings on diagnostic imaging of breast
Is R92 billable?
No — R92 is a non-billable header code. R92 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 17 billable codes beneath R92.

Excludes1 — never code together — inherited from R90-R94
The conditions below can never be reported together with R92 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 R92, but a patient may have both at the same time. When documentation supports it, R92 and the excluded code may both be reported.

How long has R92 existed?
R92 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
