Poisoning by rifampicins, undetermined, sequela

This code indicates a long-term health problem or residual effect resulting from an unconfirmed or unknown cause of rifampicin poisoning. The original poisoning event is no longer acute, but its lasting impact on the patient's health is being addressed.

Apply this code when documenting a chronic condition, disability, or other persistent sequela directly attributable to a past rifampicin poisoning where the intent (accidental, intentional self-harm, assault) could not be determined. This is used for follow-up care long after the initial poisoning has resolved.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., liver damage, neurological deficits).
• Ensure documentation clearly links the current condition to a past rifampicin poisoning of undetermined intent.
• The "S" in the 7th character indicates a sequela, meaning the patient is receiving care for the residual effects of the poisoning.
