Gonococcal infection of kidney and ureter

This diagnosis code signifies a bacterial infection of the kidney and/or ureter caused by Neisseria gonorrhoeae. It represents a specific manifestation of disseminated gonococcal infection affecting the upper urinary tract.

Apply this code when documentation clearly indicates a gonococcal etiology for pyelonephritis or ureteritis. This typically requires laboratory confirmation of N. gonorrhoeae from urine culture, kidney biopsy, or other relevant specimens, alongside clinical signs and symptoms of upper urinary tract infection.

• Ensure documentation explicitly states "gonococcal" to differentiate from other bacterial etiologies of kidney/ureter infection.
• Do not confuse this with non-gonococcal pyelonephritis (N10) or other sexually transmitted infections affecting the genitourinary system.
• Code any associated systemic manifestations of disseminated gonococcal infection, such as arthritis or dermatitis, with their respective codes.
