Poisoning by unsp psychostimulants, assault, subs encntr

This code signifies a patient presenting for follow-up care or treatment of adverse effects resulting from an intentional overdose or poisoning by an unknown psychostimulant. The poisoning was inflicted by another person with intent to harm.

Use this code when documenting subsequent encounters for complications, ongoing treatment, or recovery from a psychostimulant poisoning that was determined to be an assault. This applies after the initial acute phase of treatment.

• Requires an external cause code (X85-Y09) to fully describe the assault.
• Confirm the "subsequent encounter" designation (D) is appropriate for the patient's visit.
• Ensure the documentation clearly states the poisoning was an assault and the specific substance is unknown but falls under psychostimulants.
