Is N89 a billable ICD-10-CM code?

No. N89 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does N89 sit in the tabular list?

Diseases of the genitourinary system (N00-N99), in the block Noninflammatory disorders of female genital tract (N80-N98).

What cannot be coded together with N89?

N89 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

N89 — Other noninflammatory disorders of vagina

Non-billable headerICD-10-CM

N89 is a non-billable header ICD-10-CM code for other noninflammatory disorders of vagina. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

abnormal results from vaginal cytologic examination without histologic confirmation (R87.62-)
carcinoma in situ of vagina (D07.2)
HGSIL of vagina (R87.623)
inflammation of vagina (N76.-)
severe dysplasia of vagina (D07.2)
trichomonal leukorrhea (A59.00)
vaginal intraepithelial neoplasia [VAIN], grade III (D07.2)

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.

senile (atrophic) vaginitis (N95.2)

Other codes that can never be billed with N89

These codes carry an Excludes1 note pointing at N89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N89 alone.

N83.6Hematosalpinx
N85.7Hematometra
R87.62Abnormal cytological findings in specimens from vagina
R87.7Abnormal histological findings in specimens from female genital organs
D07.2Carcinoma in situ of vagina

Risk adjustment

N89 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 N89

9 child codes. Green means billable.
