Code Classification

  • Neoplasms
    (C00–D49)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes
      (D37-D48)
      • Neoplasm of uncertain behavior of female genital organs
        (D39)

D39.12 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of left ovary. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

This code is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.

The following anatomical sites found in the Table of Neoplasms reference the parent code D39.1 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic corpus or Neoplasm, neoplastic corpus albicans or Neoplasm, neoplastic ovary .

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Bilateral neoplasm of uncertain behavior of ovaries
  • Neoplasm of low malignant potential behavior of left ovary
  • Neoplasm of low malignant potential behavior of ovary
  • Neoplasm of uncertain behavior of left ovary
  • Neoplasm of uncertain behavior of left ovary
  • Neoplasm of uncertain behavior of ovary
  • Neoplasm of uncertain behavior of ovary
  • Neoplasm of uncertain behavior of right ovary

Clinical Classification

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

Convert D39.12 to ICD-9-CM

  • ICD-9-CM Code: 236.2 - Unc behav neo ovary
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The parent code D39.1 of the current diagnosis code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Ovarian Disorders

The ovaries are part of the female reproductive system. Women have two ovaries, one on each side of the uterus. Each ovary is about the size and shape of an almond.

The ovaries produce and store a woman's eggs. During ovulation, an ovary releases an egg. If that egg is fertilized by a sperm, a pregnancy can occur. Ovaries also make the female hormones estrogen and progesterone. When a woman goes through menopause, her ovaries stop making those hormones and releasing eggs.

Problems with the ovaries include:

  • Ovarian cancer
  • Ovarian cysts and polycystic ovary syndrome
  • Primary ovarian insufficiency
  • Ovarian torsion, a twisting of the ovary

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
