N30.0

N30.0 — Acute cystitis

Non-billable headerICD-10-CM

Excludes1 — never code together

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

irradiation cystitis (N30.4-)
trigonitis (N30.3-)

Other codes that can never be billed with N30.0

These codes carry an Excludes1 note pointing at N30.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N30.0 alone.

N02Recurrent and persistent hematuria
R31Hematuria

Risk adjustment

N30.0 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 N30.0

2 child codes. Green means billable.
