Injury of oculomotor nerve, unspecified side, subs encntr

This code signifies a subsequent encounter for an injury to the oculomotor nerve (cranial nerve III), where the specific side of the injury (left or right) is not documented. The oculomotor nerve controls most eye movements, pupil constriction, and eyelid elevation.

Apply this code for follow-up care, healing, or sequelae of an oculomotor nerve injury when the laterality is not specified. This includes situations like ongoing physical therapy, medication management for residual symptoms, or monitoring for complications after the initial injury has been treated. Documentation should clearly indicate a subsequent encounter for an unspecified oculomotor nerve injury.

• Ensure the documentation explicitly states "subsequent encounter" or indicates ongoing care for the injury.
• If the laterality (left or right) is specified in the medical record, use the more specific codes S04.11XD (right) or S04.12XD (left).
• This code should be used as a secondary diagnosis when the primary reason for the encounter is related to the ongoing management of the injury.
