Poisoning by antimycobacterial drugs, undetermined, sequela

This code signifies a long-term or residual effect resulting from an indeterminate poisoning by antimycobacterial medications. The original poisoning event's intent (accidental, intentional self-harm, assault) could not be determined. The patient is now presenting with a condition directly attributable to that past poisoning.

Apply this code when documenting a current health problem that is a direct consequence of a previous, unspecified antimycobacterial drug poisoning. This is appropriate for follow-up encounters where the acute phase of the poisoning has resolved, but the patient continues to experience related complications or conditions.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past antimycobacterial drug poisoning.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character "A" or "D".
