Q11

Q11 — Anophthalmos, microphthalmos and macrophthalmos

Non-billable headerICD-10-CM

Q11 is a non-billable header ICD-10-CM code for anophthalmos, microphthalmos and macrophthalmos. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q11

These codes carry an Excludes1 note pointing at Q11. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q11 alone.

Q10Congenital malformations of eyelid, lacrimal apparatus and orbit

Risk adjustment

Q11 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead Q11

4 child codes. Green means billable.
