Toxic effect of strychnine and salts

This code signifies the adverse systemic effects resulting from exposure to strychnine or its various salt compounds. It encompasses the physiological responses, such as seizures, muscle spasms, and respiratory distress, that occur due to the toxic properties of this substance.

Assign this code when documentation clearly indicates a patient's signs and symptoms are directly attributable to strychnine poisoning, whether from accidental ingestion, intentional overdose, or occupational exposure. Supporting documentation should detail the exposure event, the substance involved, and the resulting clinical manifestations.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Do not confuse this with codes for adverse effects of therapeutic drugs, as strychnine is not typically used therapeutically.
• Look for specific mention of "strychnine" or "strychnine salts" in the toxicology report or physician's notes.
