What This Code Means
This is a kidney infection caused by diphtheria toxin that damages the filtering structures of the kidneys. It represents a serious complication of diphtheria where the bacterial toxin affects the kidney's ability to filter waste from the blood.
Coding Tips
- •This code should only be used when diphtheria has been confirmed and documented as causing kidney damage; verify that the primary diphtheria diagnosis (A36.x) is also coded
- •This is a manifestation code that represents a complication of diphtheria, so ensure the underlying diphtheria infection is coded first as the principal diagnosis
