Inclusion terms
Alternative wording in documentation that is classified to N89.0.
- Vaginal intraepithelial neoplasia [VAIN], grade I
Excludes1 — never code together — inherited from N89
The conditions below can never be reported together with N89.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- 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 — inherited from Chapter 14
The conditions below are not part of N89.0, but a patient may have both at the same time. When documentation supports it, N89.0 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Excludes2 — not included here — inherited from N89
The conditions below are not part of N89.0, but a patient may have both at the same time. When documentation supports it, N89.0 and the excluded code may both be reported.
- senile (atrophic) vaginitis (N95.2)
How long has N89.0 existed?
N89.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with N89.0?
ICD-10-CM declares these codes mutually exclusive with N89.0 — exactly one of each pair can be correct for a given encounter.
