2024 ICD-10-CM Diagnosis Code D39.10

Approximate Synonyms

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

• Borderline epithelial tumor of ovary
• Gonadoblastoma
• Gonadoblastoma
• Gynandroblastoma of ovary
• Malignant granulosa cell tumor of ovary
• Malignant sex cord tumor of ovary
• Neoplasm of low malignant potential behavior of ovary
• Neoplasm of uncertain behavior of ovary
• Ovarian gonadoblastoma
• Sex cord tumor of ovary of uncertain behavior
• Virilizing ovarian tumor

Clinical Information

• Gonadoblastoma

  a complex neoplasm composed of a mixture of gonadal elements, such as large primordial germ cells, immature sertoli cells or granulosa cells of the sex cord, and gonadal stromal cells. gonadoblastomas are most often associated with gonadal dysgenesis, 46, xy.

• Gonadoblastoma

  a mixed germ cell/sex cord-stromal tumor characterized by the presence of large germ cells which resemble seminoma cells and small cells which resemble sertoli or granulosa cells. it occurs in the testis and the ovary and is identified in children and adults. it is often associated with gonadal dysgenesis and abnormal karyotype.

• Ovarian Gonadoblastoma

  a neoplasm that arises from the ovary and is composed of tissues that resemble dysgerminoma or seminoma and are admixed with sex cord tissues. it is found in children or young adults and usually is associated with secondary sex organs abnormalities. the majority of patients present as phenotypic females with virilization. the minority of patients present as phenotypic males with feminization. it typically affects both gonads. if a malignant germ cell component is present, it may metastasize to other anatomic sites.

• Testicular Gonadoblastoma

  a testicular mixed germ cell-sex cord-stromal tumor. it is usually associated with mixed gonadal dysgenesis and ambiguous genitalia. it is characterized by the presence of nests of large neoplastic germ cells and immature cells that resemble sertoli cells.

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 .

D39.10 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert D39.10 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.

Patient Education

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
