Poisn by antiparkns drug/centr musc-tone depr, slf-hrm, sqla

This code signifies a long-term consequence or residual effect stemming from an intentional self-harm poisoning involving antiparkinsonism medications or other central muscle-tone depressants. These sequelae can manifest as chronic organ damage, neurological deficits, or persistent psychological issues directly attributable to the original overdose.

Apply this code when documenting conditions that are a direct result of a past intentional self-harm poisoning by the specified drug classes, and these conditions are no longer acute. Examples include chronic kidney failure from a previous overdose, persistent cognitive impairment, or ongoing psychiatric conditions directly linked to the poisoning event.

• Always sequence this sequela code after the code for the specific manifestation or condition being treated.
• Ensure documentation clearly links the current condition to a past intentional self-harm poisoning by antiparkinsonism drugs or other central muscle-tone depressants.
• Do not use for acute poisoning events; this code is exclusively for residual effects.
