Poisoning by antirheumatics, NEC, assault, sequela

This code signifies a long-term complication or residual effect resulting from a poisoning event involving an antirheumatic medication, where the poisoning was intentionally inflicted by another person. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to that assault.

Use this code when documenting a chronic condition or permanent injury that is a direct consequence of an intentional overdose or administration of an antirheumatic drug by another individual. This applies to situations where the patient is now being treated for the lasting effects, such as organ damage, neurological deficits, or chronic pain syndromes, that originated from the assault.

• Always ensure documentation clearly links the current sequela to the past poisoning event and specifies the assault as the intent.
• Do not use this code for the initial acute poisoning episode; instead, use the acute poisoning code with the appropriate seventh character for initial encounter.
• Requires an additional code to specify the nature of the sequela (e.g., specific organ damage, neurological condition).
