Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to D07.0: its own notes plus those printed at D07, block D00-D09, and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Notes
General instructions on how these codes are used.
- 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).

Clinical InformationClinical
Serous Endometrial Intraepithelial Carcinoma
a precursor of endometrial serous adenocarcinoma characterized by the replacement of the normal endometrial cells by malignant glandular cells that resemble the malignant cells of invasive serous adenocarcinoma. the endometrial neoplastic process is non-invasive. it may coexist with invasive endometrial adenocarcinoma or can be associated with metastases outside the uterus, in the absence of invasive endometrial carcinoma.

Questions About D07.0Overview
What is the ICD-10 code for carcinoma in situ of endometrium?
The ICD-10-CM code for carcinoma in situ of endometrium is D07.0 (sometimes written as D070). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D07.0 (Carcinoma in situ of other and unspecified genital organs) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report carcinoma in situ of endometrium on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D07.0 group to?
When carcinoma in situ of endometrium is the principal diagnosis on an inpatient stay, it groups to MS-DRG 732, 755, 756, 754, 733, 731, with relative weights from 0.8583 to 3.5462 depending on complications. Higher weights mean higher Medicare reimbursement.
Can D07.0 be reported with D03.5?
Not as a rule. The Excludes1 note at D07, which applies to D07.0, lists "melanoma in situ of trunk (D03.5)". 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).
What is the ICD-9 equivalent of D07.0?
Under the General Equivalence Mappings, carcinoma in situ of endometrium converts to ICD-9-CM 233.2 (ca in situ uterus NEC). The mapping is approximate, so confirm the match fits the documentation.
