Excludes1 — never code together — inherited from H05
The conditions below can never be reported together with H05.4 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 malformation of orbit (Q10.7)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H05.4, but a patient may have both at the same time. When documentation supports it, H05.4 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)
