Specific Coding for Dysplasia of cervix uteriOverview

Non-specific codes like N87 require more characters. Use one of these billable codes instead:

  • Use N87.0 for Mild cervical dysplasia

  • Use N87.1 for Moderate cervical dysplasia

  • Use N87.9 for Dysplasia of cervix uteri, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to N87: its own notes plus those printed at Chapter 14. A note printed at a category, block or chapter applies to every code under it.

  • carcinoma in situ of cervix uteri (D06.-)
  • cervical intraepithelial neoplasia III [CIN III] (D06.-)
  • HGSIL of cervix (R87.613)
  • severe dysplasia of cervix uteri (D06.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 14 (N00-N99) Diseases of the genitourinary system applies to 838 codes

  • Uterine Cervical Dysplasia

    abnormal development of immature squamous epithelial cells of the uterine cervix, a term used to describe premalignant cytological changes in the cervical epithelium. these atypical cells do not penetrate the epithelial basement membrane.

Patient EducationClinical

Cervix Disorders

A cervix disorder is a problem with your cervix. The cervix is part of the female reproductive system. It is the lower, narrow end of the uterus (womb), which opens into the vagina (birth canal). The cervix has a small opening that expands during childbirth. It also allows menstrual blood to leave your body.

Questions About N87Overview

What is the ICD-10 code for dysplasia of cervix uteri?

N87 is the ICD-10-CM category for dysplasia of cervix uteri, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is N87 (Dysplasia of cervix uteri) a billable code?

No. This is a category header that groups the codes for dysplasia of cervix uteri, and headers cannot be submitted on claims. Claims for dysplasia of cervix uteri need a more specific code from this category, such as N87.0, N87.1, and N87.9.

Can N87 be reported with a code from R87.61?

Not as a rule. The Excludes1 note on N87 lists "abnormal results from cervical cytologic examination without histologic confirmation (R87.61-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
