Poisoning by antirheumatics, NEC, assault, subs

This code signifies a patient presenting for follow-up care after experiencing poisoning due to antirheumatic medications, excluding those specified elsewhere, where the poisoning was intentionally inflicted by another person. The patient is no longer in the acute phase of treatment but requires ongoing management related to the poisoning event.

This code is appropriate for documenting subsequent visits for patients who were victims of an assault involving antirheumatic drug overdose. Examples include follow-up appointments for organ damage assessment, psychological counseling, or medication adjustments stemming from the initial poisoning. It should be used after the initial acute treatment has concluded.

• Ensure documentation clearly specifies the poisoning was an assault and that this is a subsequent encounter.
• Always code the specific antirheumatic drug if known, using a more precise code if available (e.g., T39.0X3D for aspirin).
• Pair with external cause codes (V00-Y99) to fully describe the circumstances of the assault.
