Information for Patients


Kaposi Sarcoma

Also called: KS

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.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
