Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • reflux-associated pyelonephritis (N11.0)

Other codes that can never be billed with N13.7

These codes carry an Excludes1 note pointing at N13.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N13.7 alone.

  • N11.0Nonobstructive reflux-associated chronic pyelonephritis
  • N13.4Hydroureter

Risk adjustment

N13.7 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 N13.7
