Poisoning by tetracyclines, intentional self-harm, subs

This code signifies a diagnosis of poisoning due to tetracycline antibiotics, where the patient deliberately ingested the substance with the intent to harm themselves. This specific code is used when the patient is receiving follow-up care for the sequelae of the initial poisoning event, after active treatment for the acute phase has concluded.

Apply this code when a patient presents for ongoing management of complications (e.g., organ damage, psychological follow-up) resulting from a self-inflicted tetracycline overdose. It is appropriate for visits occurring after the patient has been discharged from acute care for the poisoning and is in a recovery or rehabilitation phase.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is for follow-up care.
• Always code the specific tetracycline if known (e.g., doxycycline, minocycline) using a more precise code if available and applicable.
• Do not use this code for the initial acute poisoning encounter; a different 7th character (A) would be appropriate for that phase.
