Questions About Q10Overview

What is the ICD-10 code for congenital malformations of eyelid, lacrimal apparatus and orbit?

Q10 is the ICD-10-CM category for congenital malformations of eyelid, lacrimal apparatus and orbit, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is Q10 a billable code?

No. This is a category header that groups the codes for congenital malformations of eyelid, lacrimal apparatus and orbit, and headers cannot be submitted on claims. Claims for congenital malformations of eyelid, lacrimal apparatus and orbit need a more specific code from this category, such as Q10.0, Q10.1, and Q10.2.

Can Q10 be reported with Q11.2?

Not as a rule. The Excludes1 note on Q10 lists "cryptophthalmos NOS (Q11.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
