Code Classification

  • Neoplasms
    (C00–D49)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes
      (D37-D48)
      • Neoplasm of uncertain behavior of male genital organs
        (D40)

D40.1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of neoplasm of uncertain behavior of testis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

The following anatomical sites found in the Table of Neoplasms reference this 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

Specific Coding Applicable to Neoplasm of uncertain behavior of testis

Non-specific codes like D40.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for neoplasm of uncertain behavior of testis:

  • Use D40.10 for Neoplasm of uncertain behavior of unspecified testis - BILLABLE CODE

  • Use D40.11 for Neoplasm of uncertain behavior of right testis - BILLABLE CODE

  • Use D40.12 for Neoplasm of uncertain behavior of left testis - BILLABLE CODE

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Table of Neoplasms

This 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 Disorders

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. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.
