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

This code signifies a long-term complication or residual effect resulting from an intentional overdose or poisoning by antiparkinsonism medications or other central muscle relaxants, inflicted by another person. The initial acute poisoning event has resolved, but the patient continues to experience health problems directly attributable to that assault.

This code is used when documenting chronic conditions, disabilities, or persistent symptoms that are a direct consequence of a past assault involving antiparkinsonism drugs or central muscle-tone depressants. Examples include lasting neurological deficits, organ damage, or psychological sequelae directly linked to the poisoning. It should be assigned after the acute phase of the poisoning has passed.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., G83.9 for paralysis, I69.39 for other sequelae of cerebral infarction).
• Ensure documentation clearly links the current condition to a past assault by the specified drug classes.
• Do not use this code for the initial acute poisoning event; that would require an acute poisoning code.
