Poisoning by local anesthetics, intentional self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from a deliberate overdose or misuse of a local anesthetic, such as lidocaine or bupivacaine, with the intent to cause self-harm. The poisoning event has already occurred, and the patient is now receiving ongoing management.

Apply this code when documenting subsequent encounters for patients who previously attempted suicide or intentionally harmed themselves by ingesting or administering an excessive amount of a local anesthetic. This includes visits for ongoing medical management, psychiatric evaluation, or treatment of residual effects after the initial acute poisoning.

• Always assign an additional code for the specific local anesthetic involved, if known (e.g., T41.3X1- for lidocaine).
• Remember to also code any associated mental health diagnoses, such as major depressive disorder or suicidal ideation.
• Ensure the "D" seventh character is appropriate for subsequent care; "A" is for initial encounters and "S" for sequelae.
