Definition
Surgeons who can diagnose, treat, and manage children's urinary and genital problems. A pediatric urologist devotes a minimum of 50% of his or her practice to the urologic problems of infants, children, and adolescents. Pediatric urologists generally provide the following services: the evaluation and management of voiding disorders; vesicoureteral reflux, and urinary tract infections that require surgery; surgical reconstruction of the urinary tract (kidneys, ureters, and bladder) including genital abnormalities, hypospadias, and intersex conditions; surgery for groin conditions in childhood and adolescence (undescended testes, hydrocele/hernia, varicocele).

Using 2088P0231X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
