Advrs effect of antimalari/drugs acting on bld protzoa, sqla

This code signifies a long-term or residual health problem that has resulted from a previous adverse reaction to medications used to treat malaria or other blood protozoal infections. The initial acute adverse effect has resolved, but its lasting consequences are still present.

Use this code when documenting conditions such as chronic kidney disease following an acute kidney injury caused by an antimalarial, or persistent neurological deficits after a severe neurotoxic reaction to a drug for babesiosis. It is appropriate when the adverse effect is no longer active but has left a permanent or chronic sequela.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past adverse drug event involving an antimalarial or antiprotozoal.
• This "S" seventh character indicates a sequela and should only be used for conditions that are the late effects of the adverse reaction.
