Pupillary abnormality, right eye

This code signifies an abnormal pupil in the right eye, indicating a deviation from normal pupillary size, shape, or reaction to light. It encompasses various conditions affecting the iris or its innervation, leading to a dysfunctional pupil.

Use this code when documentation specifies a pupillary abnormality affecting only the right eye. This includes conditions like anisocoria (unequal pupil size), dyscoria (abnormal pupil shape), or a fixed/dilated/constricted pupil in the right eye.

• Always specify laterality (right, left, bilateral, or unspecified) for pupillary abnormalities.
• Do not use this code for normal physiological anisocoria unless it is clinically significant and documented as an abnormality.
• Code the underlying cause of the pupillary abnormality first, if known and documented.
