Poisoning by antirheumatics, NEC, self-harm, sequela

This code indicates a long-term consequence or residual effect stemming from a deliberate overdose or self-poisoning with an antirheumatic medication that is not classified elsewhere. The initial acute poisoning event has resolved, but the patient continues to experience related health problems.

Apply this code when documenting a patient presenting with chronic organ damage, neurological deficits, or other persistent health issues directly attributable to a past intentional self-harm event involving an antirheumatic drug. This is appropriate for follow-up encounters after the acute poisoning has been treated.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Confirm the intent was self-harm; if accidental, a different intent character would be used.
• Ensure the antirheumatic agent is not more specifically classified elsewhere in the T39 category.
