About Q10

Q10 is the ICD-10-CM diagnosis code for congenital malformations of eyelid, lacrimal apparatus and orbit. It belongs to block Q10-Q18 (congenital malformations of eye, ear, face and neck) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q10.0 (ptosis), Q10.1 (ectropion), Q10.2 (entropion), Q10.3 (eyelid), Q10.4 (apparatus), Q10.5 (duct), Q10.6 (apparatus) and Q10.7 (orbit).

Don't report Q10 together with the conditions in its Excludes1 note: cryptophthalmos NOS (Q11.2) and cryptophthalmos syndrome (Q87.0).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
