About D06

D06 is the ICD-10-CM diagnosis code for carcinoma in situ of cervix uteri. It belongs to block D00-D09 (in situ neoplasms) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D06.0 (endocervix), D06.1 (exocervix), D06.7 (cervix) and D06.9 (unspecified).

Don't report D06 together with the conditions in its Excludes1 note: 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) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
