Q05.0 vs Q11
Q05.0 (Cervical spina bifida with hydrocephalus) compared with Q11 (Anophthalmos, microphthalmos and macrophthalmos), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?
Yes, when both are documented. Q11 carries an Excludes2 note covering Q05.0: “congenital malformation of cervical spine (Q05.0, Q05.5, Q67.5, Q76.0-Q76.4)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
