Poisoning by oth parasympath and spasmolytics, acc, sequela

This code describes a long-term effect or complication resulting from an accidental overdose or toxic exposure to anticholinergic or antimuscarinic medications, or other spasmolytics. It indicates that the initial acute poisoning event has resolved, but the patient continues to experience residual health problems directly attributable to that past poisoning.

Apply this code when documenting a patient presenting with chronic symptoms or conditions (e.g., persistent cognitive deficits, cardiac arrhythmias, or gastrointestinal dysmotility) that are a direct consequence of a previously treated, unintentional poisoning by anticholinergic drugs or spasmolytics. This code is appropriate after the acute phase of the poisoning has passed and the patient is no longer in active toxicological management for the initial event.

• Always use in conjunction with a code describing the specific sequela (e.g., a code for cognitive impairment, cardiac arrhythmia).
• Ensure the documentation clearly links the current condition to a past accidental poisoning by the specified drug class.
• Verify the poisoning was unintentional; do not use for intentional self-harm or assault.
