  • Postcatheterization urethral stricture

Other codes that can never be billed with N99.1

These codes carry an Excludes1 note pointing at N99.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N99.1 alone.

  • N35Urethral stricture
  • N35.0Post-traumatic urethral stricture
  • N35.8Other urethral stricture

Risk adjustment

N99.1 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.
