About coding Cryptophthalmos
The ICD-10-CM code for Cryptophthalmos is Q11.2 (Microphthalmos). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q11.2.
Within Q11 (anophthalmos, microphthalmos and macrophthalmos), Q11.2 is specifically for microphthalmos. Related codes cover cystic eyeball (Q11.0), other anophthalmos (Q11.1) and macrophthalmos (Q11.3).
Don't report Q11.2 together with the conditions in its Excludes1 note: cryptophthalmos syndrome (Q87.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
