Q64Other congenital malformations of urinary system

Non-billable headerICD-10-CM

Q64 is a non-billable header ICD-10-CM code for other congenital malformations of urinary system. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q64

These codes carry an Excludes1 note pointing at Q64. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q64 alone.

  • N32.0Bladder-neck obstruction
  • N32.3Diverticulum of bladder
  • N35Urethral stricture
  • N36.8Other specified disorders of urethra
  • Q43.6Congenital fistula of rectum and anus
  • Q54Hypospadias

Risk adjustment

Q64 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead Q64

10 child codes. Green means billable.
