Q11.2 vs Q87.0
Q11.2 (Microphthalmos) compared with Q87.0 (Congenital malformation syndromes predominantly affecting facial appearance), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Q11.2 carries an Excludes1 note covering Q87.0: “cryptophthalmos syndrome (Q87.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
