D06 is a non-billable ICD-10-CM category code for carcinoma in situ of cervix uteri, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D06.0, D06.1, D06.7, and D06.9.

Specific Coding for Carcinoma in situ of cervix uteriOverview

Non-specific codes like D06 require more characters. Use one of these billable codes instead:

  • Use D06.0 for Carcinoma in situ of endocervix

  • Use D06.1 for Carcinoma in situ of exocervix

  • Use D06.7 for Carcinoma in situ of other parts of cervix

  • Use D06.9 for Carcinoma in situ of cervix, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D06: its own notes plus those printed at block D00-D09 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

On D06 itself
  • cervical adenocarcinoma in situ
  • cervical intraepithelial glandular neoplasia
  • cervical intraepithelial neoplasia III [CIN III]
  • severe dysplasia of cervix uteri
From Block D00-D09 In situ neoplasms applies to 106 codes
  • Bowen's disease
  • erythroplasia
  • grade III intraepithelial neoplasia
  • Queyrat's erythroplasia

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • cervical intraepithelial neoplasia II [CIN II] (N87.1)
  • cytologic evidence of malignancy of cervix without histologic confirmation (R87.614)
  • high grade squamous intraepithelial lesion (HGSIL) of cervix (R87.613)
  • melanoma in situ of cervix (D03.5)
  • moderate cervical dysplasia (N87.1)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • Functional activity
  • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
  • Morphology [Histology]
  • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
  • Primary malignant neoplasms overlapping site boundaries
  • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
  • Malignant neoplasm of ectopic tissue
  • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Patient EducationClinical

Cervical Cancer

Cervical cancer is cancer that starts in the cells of the 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).

Questions About D06Overview

What is the ICD-10 code for carcinoma in situ of cervix uteri?

D06 is the ICD-10-CM category for carcinoma in situ of cervix uteri, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D06 (Carcinoma in situ of cervix uteri) a billable code?

No. This is a category header that groups the codes for carcinoma in situ of cervix uteri, and headers cannot be submitted on claims. Claims for carcinoma in situ of cervix uteri need a more specific code from this category, such as D06.0, D06.1, and D06.7.

Can D06 be reported with N87.1?

Not as a rule. The Excludes1 note on D06 lists "cervical intraepithelial neoplasia II [CIN II] (N87.1)". 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).
