Poisn by oth parasympath and spasmolytics, slf-hrm, sequela

This code signifies a long-term consequence or complication arising from an intentional self-harm event involving an overdose or misuse of anticholinergic or antimuscarinic medications, or other spasmolytics. It indicates that the acute poisoning has resolved, but the patient is now experiencing residual effects directly attributable to that past event.

Use this code when documenting a patient presenting with chronic neurological, gastrointestinal, cardiac, or other systemic sequelae (e.g., persistent cognitive deficits, chronic constipation, dysrhythmias) that are directly linked to a prior, intentional self-poisoning with anticholinergic or spasmolytic drugs. This code is appropriate for follow-up encounters addressing these lasting effects, not the initial acute poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional self-harm poisoning.
• Do not use for acute poisoning events; those require codes from the 'A' or 'D' seventh character categories.
