Toxic effect of strychnine and its salts, undetermined, init

This code signifies a poisoning or adverse reaction due to strychnine or its derivatives, where the intent (accidental, intentional self-harm, assault) cannot be determined from the available documentation. Strychnine is a highly toxic substance that can cause severe neurological symptoms, including muscle spasms, convulsions, and respiratory arrest.

This code is appropriate when a patient presents with symptoms consistent with strychnine poisoning, and the medical record does not specify whether the exposure was accidental, intentional, or due to assault. It should be used for the initial encounter for treatment of the acute toxic effects.

• Always strive to clarify the intent of the poisoning if possible, as this code indicates "undetermined."
• Ensure documentation supports the "initial encounter" designation for the acute phase of treatment.
• Code any associated signs, symptoms, or complications of strychnine toxicity in addition to this code.
