C46.9 is a billable ICD-10 code used to specify a medical diagnosis of kaposi's sarcoma, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like C46.9 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Endemic Kaposi sarcoma
- Kaposi sarcoma of viscus
- Kaposi's sarcoma
- Kaposi's sarcoma - sporadic
- Kaposi's sarcoma not associated with acquired immunodeficiency syndrome
- Kaposi's sarcoma of multiple organs
- Kaposi's sarcoma with AIDS
- Malignant neoplasm with AIDS
- Malignant neoplastic disease co-occurrent with human immunodeficiency virus infection

Kaposi sarcoma (KS) is a cancer that causes patches of abnormal tissue to grow under the skin, in the lining of the mouth, nose, and throat, in lymph nodes, or in other organs. These patches, or lesions, are usually red or purple. They are made of cancer cells, blood vessels, and blood cells.
KS is caused by infection with human herpesvirus-8 (HHV-8). Most people infected with HHV-8 don't get KS. It usually happens in:
- People with weak immune systems, due to HIV/AIDS, drugs taken after an organ transplant, or another disease
- Older men of Jewish or Mediterranean descent
- Young men in Africa
The skin lesions may not cause symptoms. But they can spread to other parts of the body, especially in people with HIV/AIDS. If they spread to the digestive tract or lungs, they can cause bleeding. Lesions on the lungs can also make it hard to breathe.
Treatment depends on where the lesions are and how bad they are. Options include radiation therapy, surgery, chemotherapy, and biologic therapy. People with HIV/AIDS also take HIV/AIDS medicines.
