Toxic effect of strychnine and its salts, accidental, subs

This code signifies an adverse health effect resulting from unintentional exposure to strychnine or its derivatives. The patient is in the recovery phase, receiving follow-up care for complications or sequelae of the initial poisoning. Symptoms can range from muscle spasms and convulsions to respiratory failure, depending on the dose and individual sensitivity.

Apply this code when documenting subsequent encounters for patients who have experienced accidental strychnine poisoning. This includes follow-up visits for ongoing management of neurological symptoms, organ damage, or other lingering effects after the acute phase has passed. It is appropriate for situations where the patient is still under active treatment or monitoring related to the toxic exposure.

• Always use in conjunction with codes for the specific manifestations or complications of the strychnine poisoning.
• Ensure documentation clearly states the accidental nature of the exposure and that this is a subsequent encounter.
• Distinguish carefully from initial encounters (A) or sequela encounters (S) for the same condition.
