Bitten by orca, subsequent encounter

This code indicates a patient presenting for follow-up care or treatment of injuries sustained from an orca bite. It signifies that the initial encounter for the injury has already been coded, and the current visit addresses ongoing management, complications, or healing of the bite wound.

Apply this code when a patient returns to a healthcare provider for a subsequent visit related to an orca bite. This includes scenarios such as wound checks, dressing changes, antibiotic management for infection, or evaluation of residual pain or functional limitations after the initial injury.

• Always pair this code with an external cause code (e.g., Y92.830 for ocean as place of occurrence).
• Ensure the initial encounter for the orca bite (W56.21XA) has been previously reported.
• Do not use for initial treatment; reserve for follow-up care.
