Poisoning by penicillins, assault, sequela

This code indicates a long-term or residual effect resulting from a poisoning by penicillin, where the poisoning was intentionally inflicted by another person. It signifies that the acute phase of the poisoning has passed, and the patient is now experiencing a chronic condition or complication directly attributable to that event.

This code is appropriate for documenting conditions such as persistent organ damage, neurological deficits, or chronic allergic reactions that developed as a direct consequence of a past penicillin poisoning due to assault. It should be used when the patient is being treated for these lasting effects, not for the initial acute poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past penicillin poisoning by assault.
• Do not use for acute poisoning; refer to the appropriate acute poisoning codes (T36.0X1-T36.0X4) for initial encounters.
