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)

D40.8 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of other specified male genital organs. 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 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 this diagnosis code given the correct histological behavior: Neoplasm, neoplastic cord (true) (vocal) spermatic ; Neoplasm, neoplastic corpus cavernosum ; Neoplasm, neoplastic corpus penis ; Neoplasm, neoplastic ejaculatory duct ; Neoplasm, neoplastic epididymis ; Neoplasm, neoplastic foreskin ; Neoplasm, neoplastic genital organ or tract male NEC specified site NEC ; etc

Approximate Synonyms

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

  • Neoplasm of prepuce
  • Neoplasm of uncertain behavior of body of penis
  • Neoplasm of uncertain behavior of epididymis
  • Neoplasm of uncertain behavior of glans penis
  • Neoplasm of uncertain behavior of penis
  • Neoplasm of uncertain behavior of prepuce
  • Neoplasm of uncertain behavior of scrotum
  • Neoplasm of uncertain behavior of spermatic cord
  • Neoplasm of uncertain behavior of vas deferens
  • Neoplasm of vas deferens
  • Penile intraepithelial neoplasia

Clinical Classification

Clinical Information

  • Epididymis

    the convoluted cordlike structure attached to the posterior of the testis. epididymis consists of the head (caput), the body (corpus), and the tail (cauda). a network of ducts leaving the testis joins into a common epididymal tubule proper which provides the transport, storage, and maturation of spermatozoa.
  • Foreskin

    the double-layered skin fold that covers the glans penis, the head of the penis.
  • Spermatic Cord

    either of a pair of tubular structures formed by ductus deferens; arteries; veins; lymphatic vessels; and nerves. the spermatic cord extends from the deep inguinal ring through the inguinal canal to the testis in the scrotum.
  • Spermatic Cord Torsion

    the twisting of the spermatic cord due to an anatomical abnormality that left the testis mobile and dangling in the scrotum. the initial effect of testicular torsion is obstruction of venous return. depending on the duration and degree of cord rotation, testicular symptoms range from edema to interrupted arterial flow and testicular pain. if blood flow to testis is absent for 4 to 6 h, spermatogenesis may be permanently lost.
  • Sterilization Reversal

    procedures to reverse the effect of reproductive sterilization and to regain fertility. reversal procedures include those used to restore the flow in the fallopian tube or the vas deferens.
  • Vas Deferens

    the excretory duct of the testes that carries spermatozoa. it rises from the scrotum and joins the seminal vesicles to form the ejaculatory duct.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Neoplasm of uncertain behavior of skin of male genital organs

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 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 .

Convert D40.8 to ICD-9-CM

  • ICD-9-CM Code: 236.6 - Unc behav neo male NEC
    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

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


Penis Disorders

Problems with the penis can cause pain and affect a man's sexual function and fertility. Penis disorders include:

  • Erectile dysfunction - inability to get or keep an erection
  • Priapism - a painful erection that does not go away
  • Peyronie's disease - bending of the penis during an erection due to a hard lump called a plaque
  • Balanitis - inflammation of the skin covering the head of the penis, most often in men and boys who have not been circumcised
  • Penile cancer - a rare form of cancer, highly curable when caught early

Testicular Cancer

What is testicular cancer?

Testicular cancer is a cancer that develops in the tissues of one or both testicles. The testicles, or testes, are part of the male reproductive system. They make male hormones and sperm. They are two egg-shaped glands inside the scrotum, a sac of loose skin that lies below the penis. You can get cancer in one or both testicles.

Who is most likely to develop testicular cancer?

Testicular cancer is very rare. You can get it at any age, but it is most common in men between the ages of 20 and 39. It is also more common in those who:

  • Have had abnormal testicle development
  • Have had an undescended testicle, a condition in which one or both testicles fail to move into the scrotum before birth
  • Have had testicle cancer before
  • Have a family history of the cancer
  • Are White

What are the symptoms of testicular cancer?

The symptoms of testicular cancer may include:

  • A painless lump or swelling in either testicle
  • A change in how the testicle feels
  • A dull ache in the lower abdomen (belly) or the groin (the area where the thigh meets the abdomen)
  • A sudden build-up of fluid in the scrotum
  • Pain or discomfort in a testicle or in the scrotum

How is testicular cancer diagnosed?

To find out if you have testicular cancer, your health care provider may use:

  • A physical exam.
  • Blood tests.
  • An ultrasound of the testicles.
  • An inguinal orchiectomy, which is a procedure to remove the entire testicle. A tissue sample from the testicle is viewed under a microscope to check for cancer cells.

What are the treatments for testicular cancer?

Testicular cancer can usually be cured.The treatment options include:

  • Surgery (if the testicle has not already been removed during diagnosis).
  • Radiation therapy.
  • Chemotherapy.
  • High-dose chemotherapy with stem cell transplant.
  • Surveillance, which might be done after surgery. It means that your provider will closely follow your condition with regular exams and tests. You won't get any further treatment unless there are changes in your test results.

Some of the treatments may also cause infertility. If you may want to have children later on, you should consider sperm banking before treatment.

After you have finished your treatment, you will need regular follow-up testing to make sure that the cancer has not come back. If you have had cancer in one testicle, you have a higher risk of getting cancer in the other testicle. So it's important to check the other testicle regularly and let your provider know if you notice any changes or unusual symptoms.

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.
