Poisoning by skeletal muscle relaxants, undetermined, init

This code signifies an adverse event resulting from exposure to skeletal muscle relaxants, specifically neuromuscular blocking agents, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The "initial encounter" indicates that the patient is receiving active treatment for the poisoning.

This code is appropriate when a patient presents with signs and symptoms of poisoning from a neuromuscular blocking agent, and the circumstances surrounding the exposure are unclear or undocumented. It should be used for the initial hospitalization or outpatient visit where the poisoning is first evaluated and treated.

• Always assign an additional code for the specific manifestation(s) of the poisoning.
• Do not use this code if the intent of the poisoning is known (e.g., accidental, intentional self-harm); instead, select the appropriate intent code.
• Ensure documentation clearly supports the "undetermined" intent and the "initial encounter" for active treatment.
