Specific Coding for Benign neoplasm of ovaryOverview

Non-specific codes like D27 require more characters. Use one of these billable codes instead:

  • Use D27.0 for Benign neoplasm of right ovary

  • Use D27.1 for Benign neoplasm of left ovary

  • Use D27.9 for Benign neoplasm of unspecified ovary

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D27: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

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.

Use Additional Code

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.

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).

Excludes1 2

These codes carry an Excludes1 note naming D27: they are not reported together with it, unless the two conditions are unrelated.

    benign neoplasm of ovary (D27.-)
  • N83.2 Other and unspecified ovarian cysts
    neoplastic ovarian cyst (D27.-)

Clinical InformationClinical

  • Luteoma

    an ovarian neoplasm composed of luteal cells derived from luteinized granulosa cells and theca cells. luteomas respond to gonadotropins, and vary in their hormone production (progesterone; estrogens; or androgens). during pregnancy, a transient type of luteoma may develop due to an exaggerated luteinization of the ovary.

  • Thecoma

    a gonadal stromal neoplasm composed only of theca cells, occurring mostly in the postmenopausal ovary. it is filled with lipid-containing spindle cells and produces estrogens that can lead to endometrial hyperplasia; uterine hemorrhage; or other malignancies in postmenopausal women and sexual precocity in girls. when tumors containing theca cells also contain fibroblasts, they are identified as thecoma-fibroma tumors with less active hormone production.

Patient EducationClinical

Ovarian Cysts

The ovaries are part of the female reproductive system. They produce a woman's eggs and make female hormones. Ovarian cysts are fluid-filled sacs in or on an ovary. They usually form during ovulation, when the ovary releases an egg. They are usually harmless and go away by themselves. Most women have them sometime during their lives.

Questions About D27Overview

What is the ICD-10 code for benign neoplasm of ovary?

D27 is the ICD-10-CM category for benign neoplasm of ovary, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D27 (Benign neoplasm of ovary) a billable code?

No. This is a category header that groups the codes for benign neoplasm of ovary, and headers cannot be submitted on claims. Claims for benign neoplasm of ovary need a more specific code from this category, such as D27.0, D27.1, and D27.9.

Does D27 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code to identify any functional activity.. The additional code is reported after D27.
