Injury of oculomotor nerve, unspecified side, init encntr

This code signifies damage to the third cranial nerve (oculomotor nerve) without specifying which eye is affected. This nerve controls most eye movements, pupillary constriction, and eyelid elevation. Injury can result in symptoms such as ptosis, diplopia, and a dilated pupil.

Use this code for a newly diagnosed or treated injury to the oculomotor nerve when the laterality (left or right eye) is not documented. This applies to initial encounters for conditions like trauma-induced nerve damage, compression from a mass, or ischemic injury affecting the third cranial nerve. Documentation should clearly state an oculomotor nerve injury but lack specific side information.

• Always strive for greater specificity regarding laterality (left or right eye) if documented.
• Distinguish from other cranial nerve palsies; ensure documentation specifically points to the oculomotor nerve.
• Remember the "A" at the end indicates an initial encounter for active treatment of the injury.
