N32.0Bladder-neck obstruction

Billable / specific codeICD-10-CM

N32.0 is a billable, specific ICD-10-CM code for bladder-neck obstruction. It is valid for submission on a claim.

Excludes1 — never code together

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

  • congenital bladder-neck obstruction (Q64.3-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Bladder-neck stenosis (acquired)

Risk adjustment

N32.0 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.

N32.0 is named in 4 Medicare coverage policies 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
