Other anomalies of pupillary function

This code represents various congenital or acquired abnormalities affecting the pupil's normal function, excluding specific conditions like anisocoria, miosis, or mydriasis. It encompasses a range of pupillary dysfunctions that are not otherwise classified, impacting light reflex, accommodation, or other pupillary responses.

Use this code when documentation indicates an anomaly of pupillary function that doesn't fit more specific ICD-10-CM codes. This could include conditions like Adie's tonic pupil (when not specified as unilateral/bilateral), Argyll Robertson pupil (when not due to syphilis), or other ill-defined pupillary abnormalities. Documentation should clearly state the presence of a pupillary anomaly and rule out more specific diagnoses.

• Ensure the medical record explicitly states "other" or "unspecified" pupillary anomaly if a more precise diagnosis isn't available.
• Do not use this code for anisocoria (H57.01-), miosis (H57.02), or mydriasis (H57.03), as these have their own specific codes.
• Always sequence this code after the underlying cause if known and documented (e.g., neurological condition leading to pupillary dysfunction).
