]> M-9140 Note: This scheme cannot be compared to either the Historic Stage or the 1977 Summary Stage schemes. ¬appsizenontnm; CS Extension Note 1: In the United States and Canada, Kaposisarcoma is usually an illness related to Acquired Immunodeficiency Syndrome (AIDS) which affects primarily the skin; however, lesions may also form in the connective tissue, mucosa (e.g. oral cavity) or visceral organs (e.g. lungs). For connective tissue tumors (C49._), use extension codes for skin. Note 2: Choice of CS Extension codes for Kaposi sarcoma depends on number and location of lesions. For example, use code 110 for a single lesion involving skin; use code 210 for multiple lesions involving skin. Use code 250 for any number of lesions involving both skin and viscera.

Note 2: When coding Regional Nodes Positive and Regional Nodes Examined, only include regional nodes. Do not include distant nodes coded in CS Lymph Nodes. If the only information available is for Lymph Nodes, NOS, coded as 800 in CS Lymph Nodes, assume these are regional nodes for coding Regional nodes Positive and Regional Nodes Examined.

Note 3: Assign code 000 if the History and Physical, progress notes, and consultations make no mention of B symptoms. Code Description 000 No B symptoms (asymptomatic) 010 020 Persistent diarrhea lasting longer than two weeks 888 988 999 CS Site-Specific Factor 3 Ulceration and Edema Note 1: Tumor associated edema or ulceration is considered a poor risk. Note 2: Tumor associated edema or ulceration is usually histologically confirmed and documented in the pathology report. If tumor associated edema or ulceration is diagnosed clinically without pathologic confirmation, use code 040. Note 3: If there is no documentation or no mention of ulceration or edema in the pathology report or clinical examination, assume ulceration and edema are not present and use code 000. Code Description 000 No ulceration or edema present 010 Ulceration present 020 Edema present 030 Ulceration and edema present 040 Clinical diagnosis of edema and/or ulceration 888 988 999 CS Site-Specific Factor 4 CD4 Cell Count Note 1: The CD4 cell count is used to monitor how well the immune system is working in a patient who is Human Immunodeficiency Virus (HIV) positive. A blood test measures the number of CD4 T-cells in each microliter (ul) of blood. The measurement may also be in CD4 cells per cubic millimeter of blood. One microliter (ul) is equivalent to 1 cubic millimeter of fluid. A low CD4 count (less than 200) indicates a weakened immune system. For Kaposi Sarcoma patients, a CD4 count lower than 200 is a poor risk factor. Note 2: Record the CD4 count at the time of the Kaposi Sarcoma diagnosis as documented in the patient record. If the CD4+ count is 980 or greater use code 980. If the test is done but the actual value is not available or not stated, use code 997. Note 3: If the patient is HIV negative, use code 987. Note 4: Record the actual value of the CD4 count as documented in the patient record. If the actual CD4+ count is 980 or greater, use code 980.
