Infection of kidney following delivery

This code signifies a kidney infection, such as pyelonephritis or other renal infections, that develops as a complication following childbirth. It indicates a postpartum infectious process specifically affecting the renal system.

Assign this code when documentation clearly states a diagnosis of kidney infection occurring after delivery, during the puerperium. This includes conditions like acute pyelonephritis or other specified kidney infections directly linked to the recent delivery.

• Ensure documentation specifies the kidney as the site of infection and its direct relationship to the delivery.
• Do not use for urinary tract infections (UTIs) not explicitly involving the kidney.
• Sequence this code after the primary obstetric code if the infection is a complication of the delivery.
