Adverse effect of rifampicins, sequela

This code signifies a patient experiencing an undesirable or harmful reaction to a rifampicin-class antibiotic, where the reaction is a long-term consequence or complication of the initial adverse event. It indicates that the adverse effect is no longer acute but has resulted in a persistent condition or sequela.

This code is appropriate when documenting a chronic or residual condition directly resulting from a past adverse reaction to rifampicin. Examples include permanent organ damage, persistent neurological deficits, or chronic dermatological issues that developed after an acute rifampicin adverse effect. It should be used when the patient is being treated for the lasting impact of the drug reaction, not the acute reaction itself.

• Always sequence this code after the code for the specific sequela (e.g., chronic hepatitis, peripheral neuropathy).
• Ensure documentation clearly links the current sequela to a past adverse effect of rifampicin.
• Verify that the adverse effect is indeed a sequela and not an ongoing acute reaction, which would require a different code.
