N34Urethritis and urethral syndrome

Non-billable headerICD-10-CM

N34 is a non-billable header ICD-10-CM code for urethritis and urethral syndrome. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • Reiter's disease (M02.3-)
  • urethritis in diseases with a predominantly sexual mode of transmission (A50-A64)
  • urethrotrigonitis (N30.3-)

Use additional code

Add a secondary code to capture the detail described below.

  • code (B95-B97), to identify infectious agent.

Other codes that can never be billed with N34

These codes carry an Excludes1 note pointing at N34. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N34 alone.

  • N39.0Urinary tract infection, site not specified

Risk adjustment

N34 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 N34

4 child codes. Green means billable.
