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

This code signifies a patient presenting for follow-up care related to an intentional overdose or self-poisoning with antiparkinsonism medications or other central muscle-tone depressants. The initial acute event has passed, and the patient is now receiving ongoing management for the effects of the poisoning.

Apply this code when documenting subsequent encounters for patients who previously attempted self-harm by ingesting antiparkinsonism drugs or other central muscle-tone depressants. This includes visits for monitoring, management of lingering side effects, or psychiatric follow-up directly related to the self-poisoning event.

• Ensure the documentation clearly indicates the encounter is for follow-up care after the initial poisoning event.
• Verify the specific drug class involved aligns with "antiparkinsonism drugs and other central muscle-tone depressants."
• Always sequence this code after any codes for the specific sequelae or complications resulting from the poisoning.
