Exposure to domestic wiring and appliances, sequela

This code indicates a long-term or late-occurring health condition resulting from a past exposure to electrical current from household wiring or appliances. These sequelae can manifest as chronic pain, neurological deficits, scarring, or other persistent issues that arise after the initial injury has healed.

Assign this code when documenting a current health problem that is a direct consequence of an electrical injury from domestic wiring or appliances that occurred in the past. This is appropriate for follow-up visits where the patient is being treated for the lasting effects of such an incident, not the acute injury itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past electrical exposure from domestic sources.
• Do not use for acute electrical burns or injuries; those require codes from the T75.4- or T20-T32 series.
