Excludes2 — not included here
The conditions below are not part of N64.5, but a patient may have both at the same time. When documentation supports it, N64.5 and the excluded code may both be reported.
- abnormal findings on diagnostic imaging of breast (R92.-)
Excludes1 — never code together — inherited from N60-N65
The conditions below can never be reported together with N64.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- disorders of breast associated with childbirth (O91-O92)
