ICD-10 Code C46.7 – Kaposi’s sarcoma of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C46.7 – Kaposi’s sarcoma of other sites
What it is
C46.7 identifies Kaposi’s sarcoma when it arises in sites other than the more specifically listed locations. Use this code for a documented Kaposi’s sarcoma diagnosis involving another anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Kaposi’s sarcoma commonly presents as violaceous or brownish skin or mucosal lesions, nodules, or plaques, but the coded site should match the recorded location.
When to use this code
Use C46.7 when the clinician documents Kaposi’s sarcoma in an “other site” not captured by a more specific code. This may include unusual anatomic locations or site descriptions that do not fit another C46 category. If the record names a more specific site, code that instead.
Do not use for
Do not use this code for Kaposi’s sarcoma at a specifically listed site, or when the diagnosis is only suspected. Check documentation if the site is unclear or if another Kaposi’s sarcoma code applies.
Coding tip
Confirm the exact anatomic site in the note before assigning C46.7.
