Poisoning by antimycobac drugs, accidental, sequela

This code signifies a long-term complication or residual effect stemming from an accidental overdose or unintended exposure to antimycobacterial medications. These sequelae are the lasting health problems that persist after the acute phase of the poisoning has resolved. Examples include chronic organ damage, neurological deficits, or persistent metabolic disturbances.

Apply this code when documenting a patient presenting with a current condition that is a direct and lasting consequence of a past, unintentional poisoning by an antimycobacterial drug. This is appropriate for follow-up encounters where the focus is on managing these chronic effects, rather than the acute poisoning event itself.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., chronic hepatitis, peripheral neuropathy).
• Ensure documentation clearly links the current condition to the past antimycobacterial drug poisoning.
• Do not use for acute poisoning events; those require codes from the initial encounter for poisoning.
