Excludes1 — never code together — inherited from H02
The conditions below can never be reported together with H02.51 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital malformations of eyelid (Q10.0-Q10.3)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H02.51, but a patient may have both at the same time. When documentation supports it, H02.51 and the excluded code may both be reported.
