Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the Q10 Code Range
These conditions affect the eyelid, tear system, or eye socket and are present at birth.
The subdivisions first separate eyelid conditions: Q10.0 describes a drooping eyelid, Q10.1 an outward-turning eyelid, and Q10.2 an inward-turning eyelid. Q10.3 covers other eyelid malformations.
The tear-system subdivisions distinguish absent structures in Q10.4, a narrowed tear duct in Q10.5, and other malformations in Q10.6. Q10.7 covers malformations of the orbit, the eye socket.
