Poisoning by local anesthetics, intentional self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of a local anesthetic agent, such as lidocaine or bupivacaine, with the intent to cause harm. The patient is in the initial phase of treatment for this poisoning.

Apply this code when documenting the initial encounter for a patient admitted to the emergency department or hospital due to an overdose of a local anesthetic, where the overdose is explicitly determined to be self-inflicted. This includes cases where the patient explicitly states self-harm intent or when evidence strongly suggests it.

• Always assign an additional code for the specific local anesthetic involved, if known.
• Remember to use an external cause code (e.g., X64.-) to describe the intent and circumstances of the poisoning.
• Ensure documentation clearly supports the "intentional self-harm" and "initial encounter" aspects for accurate code assignment.
