About coding macrophthalmos
The ICD-10-CM code for macrophthalmos is Q11.3 (Macrophthalmos). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q11.3.
Within Q11 (anophthalmos, microphthalmos and macrophthalmos), Q11.3 is specifically for macrophthalmos. Related codes cover cystic eyeball (Q11.0), other anophthalmos (Q11.1) and microphthalmos (Q11.2).
Don't report Q11.3 together with the conditions in its Excludes1 note: macrophthalmos in congenital glaucoma (Q15.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
