Exposure to other electric current, subsequent encounter

This code signifies a follow-up encounter for a patient who has previously sustained an injury due to contact with an electric current other than a power line or domestic wiring. It indicates that the patient is receiving ongoing care, evaluation, or treatment for the sequelae of such an exposure.

Apply this code when a patient presents for a subsequent visit related to an injury from an electric current source like a faulty appliance, industrial machinery, or a lightning strike (if not otherwise specified as power line/domestic). This includes follow-up appointments for burns, cardiac issues, neurological symptoms, or other complications arising from the initial electrical exposure.

• Always pair this code with an external cause code (e.g., X99.-, Y00.-) to specify the intent of the exposure, if known.
• Ensure a primary diagnosis code for the specific injury (e.g., T75.4XXA for electrocution, T20-T32 for burns) is also reported.
• Confirm the encounter is indeed "subsequent" and not the initial treatment for the injury.
