Contusion of eyeball and orbital tissues, left eye, subs

This code signifies a bruise to the left eye, affecting both the globe and the surrounding soft tissues within the orbit. It indicates that the patient is receiving follow-up care for an injury that occurred previously, rather than the initial treatment.

Use this code for a patient presenting for ongoing management, such as monitoring healing, addressing persistent symptoms, or evaluating complications, of a left eye contusion. Documentation should clearly state "left eye," "contusion," and indicate that this is not the initial encounter for the injury.

• Ensure documentation specifies "left eye" to differentiate from right (S05.11XD) or unspecified (S05.10XD).
• The 7th character "D" (subsequent encounter) is crucial; use "A" for initial treatment of the same injury.
• Always code the underlying cause of the injury (e.g., fall, assault) with an external cause code.
