Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to D39.11: its own notes plus those printed at D39.1, block D37-D48, and Chapter 2. A note printed at a category, block or chapter applies to every code under it.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- neoplasms of unspecified behavior (D49.-)

Add a second code, after this one, to fully describe the condition.
- code to identify any functional activity.
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).

Ovarian Disorders
The ovaries are a pair of female reproductive glands that make eggs and female hormones. Women have one ovary on each side of the uterus (where a fetus grows during pregnancy). Each ovary is about the size and shape of an almond.

What is the ICD-10 code for neoplasm of uncertain behavior of right ovary?
The ICD-10-CM code for neoplasm of uncertain behavior of right ovary is D39.11 (sometimes written as D3911). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D39.11 (Neoplasm of uncertain behavior of ovary) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report neoplasm of uncertain behavior of right ovary on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D39.11 group to?
When neoplasm of uncertain behavior of right ovary 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 D39.11 be reported with a code from D49?
Not as a rule. The Excludes1 note at block D37-D48, which applies to D39.11, lists "neoplasms of unspecified behavior (D49.-)". 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).
