Kaposi's sarcoma of other sites

This code identifies Kaposi's sarcoma affecting anatomical sites not specifically categorized elsewhere, such as the gastrointestinal tract, lungs, or lymph nodes. It represents a multifocal vascular tumor often associated with human herpesvirus 8 (HHV-8) infection, particularly in immunocompromised individuals.

Assign this code when documentation specifies Kaposi's sarcoma in locations like the liver, spleen, pancreas, or adrenal glands. It is appropriate when the primary site is clearly identified as "other" and not covered by more specific C46 subcategories. Documentation should clearly state the affected "other" site.

• Do not use this code for cutaneous, soft tissue, palatal, or lymph node Kaposi's sarcoma, as those have more specific codes.
• Always code the underlying cause, such as HIV infection (B20), if present, as a secondary diagnosis.
• Ensure the medical record explicitly identifies the "other" site to justify using this less specific code.
