Poisoning by oth parasympath and spasmolytics, acc, subs

This code signifies an accidental poisoning due to a medication that blocks the action of acetylcholine, such as anticholinergics, antimuscarinics, or spasmolytics. The patient is in the recovery phase or receiving follow-up care for the initial poisoning event. Symptoms can range from dry mouth and blurred vision to delirium and cardiac arrhythmias.

This code is appropriate when a patient presents for ongoing treatment, monitoring, or evaluation of complications stemming from an unintentional overdose or exposure to an anticholinergic or spasmolytic agent. This includes follow-up appointments after discharge from an acute care setting or subsequent visits to manage persistent side effects.

• Ensure the encounter is for follow-up care, not the initial acute poisoning.
• Verify the specific drug class involved is an anticholinergic, antimuscarinic, or spasmolytic.
• Confirm the poisoning was accidental; intentional poisonings require different codes.
