About the Q10–Q18 Code Range
These conditions affect the eyes, ears, face, or neck from birth. The categories group them by body part, then by the structure or type of malformation named in each subdivision.
Q10 separates eyelid, tear-system, and eye-socket malformations. Q11 distinguishes cystic eyeballs from absent, small, or large eyeballs. Q12 groups lens malformations, while Q13 and Q14 separate malformations of the front and back parts of the eye. Q15 holds other eye malformations, including congenital glaucoma.
The ear categories distinguish malformations that impair hearing, under Q16, from other ear malformations, under Q17. Q18 groups other malformations of the face and neck.
