Table of Contents
D40.10 is a billable ICD-10 code used to specify a medical diagnosis of neoplasm of uncertain behavior of unspecified testis. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
This code is applicable to male patients only. It is clinically and virtually impossible to use this code on a non-male patient.
The following anatomical sites found in the Table of Neoplasms reference the parent code D40.1 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic testis, testes ; Neoplasm, neoplastic testis, testes descended ; Neoplasm, neoplastic testis, testes ectopic ; Neoplasm, neoplastic testis, testes retained ; Neoplasm, neoplastic testis, testes scrotal ; Neoplasm, neoplastic testis, testes undescended ; Neoplasm, neoplastic testis, testes unspecified whether descended or undescended ; etc
Unspecified diagnosis codes like D40.10 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Gonadoblastoma
- Gonadoblastoma
- Gonadoblastoma of testis
- Granulosa cell tumor of testis of uncertain behavior
- Leydig cell tumor of testis of uncertain behavior
- Neoplasm of uncertain behavior of testicular sex cord
- Neoplasm of uncertain behavior of testis
- Neoplasm of uncertain behavior of undescended testis
- Neoplasm of undescended testis
- Sertoli cell tumor of testis
- Sex cord stromal tumor of testis
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 Code Edits are applicable to this code:
- Diagnoses for males only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to MALES only .

| 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 D40.1 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
Testicular Cancer
Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. You can get cancer in one or both testicles.
Testicular cancer mainly affects young men between the ages of 20 and 39. It is also more common in men who:
- Have had abnormal testicle development
- Have had an undescended testicle
- Have a family history of the cancer
Symptoms include pain, swelling, or lumps in your testicles or groin area. Doctors use a physical exam, lab tests, imaging tests, and a biopsy to diagnose testicular cancer. Most cases can be treated, especially if found early. Treatment options include surgery, radiation, and/or chemotherapy. Regular exams after treatment are important.
Treatments may also cause infertility. If you may want children later on, you should consider sperm banking before treatment.
