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 Q17 Code Range
These ear differences are present at birth and can affect the ear’s size, shape, or position.
The subdivisions distinguish an extra ear structure (Q17.0), a large ear (Q17.1), and a small ear (Q17.2). They also separate other misshapen ears (Q17.3), misplaced ears (Q17.4), and prominent ears (Q17.5). The remaining subdivisions distinguish other specified ear malformations (Q17.8) from an unspecified ear malformation (Q17.9).
