Is N34.0 a billable ICD-10-CM code?

Yes. N34.0 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does N34.0 sit in the tabular list?

Diseases of the genitourinary system (N00-N99), in the block Other diseases of the urinary system (N30-N39).

What cannot be coded together with N34.0?

N34.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

N34.0

N34.0 — Urethral abscess

Billable / specific codeICD-10-CM

N34.0 is a billable, specific ICD-10-CM code for urethral abscess. 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.

urethral caruncle (N36.2)

Inclusion terms

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

Abscess (of) Cowper's gland
Abscess (of) Littré's gland
Abscess (of) urethral (gland)
Periurethral abscess

Excludes2 inherited from the categories above N34.0

Also inherited, and the opposite of Excludes1: these conditions are not part of N34.0, but a patient can have both, so you may code both.

Written on N34 — Urethritis and urethral syndrome

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

Other codes that can never be billed with N34.0

These codes carry an Excludes1 note pointing at N34.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N34.0 alone.

N39.0Urinary tract infection, site not specified

Risk adjustment

N34.0 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.

How N34.0 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to N34.0.

Abscess›bulbourethral gland
Abscess›Cowper's gland
Abscess›lacunar
Abscess›Littre's gland
