ICD-10 Code C46.2 – Kaposi’s Sarcoma of Palate (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C46.2 – Kaposi’s sarcoma of palate
What it is
C46.2 identifies Kaposi’s sarcoma involving the palate, a vascular tumor that appears in the mouth. Use it when documentation specifically states palatal Kaposi’s sarcoma.
Clinical signs
Typical findings include a violaceous, red, or brownish oral lesion on the palate that may be flat, raised, or nodular. Clinical features vary; refer to documentation.
When to use this code
Use C46.2 when the provider documents Kaposi’s sarcoma limited to the palate or names the palate as the site. You may also use it when pathology or specialist notes confirm palatal involvement. If the site is not stated, check documentation before coding.
Do not use for
Do not use this code for Kaposi’s sarcoma at another oral site, skin, or internal organ. Do not assign it when the record only says “oral lesion” without palatal confirmation.
Coding tip
Code the documented anatomic site exactly; when the palate is not clearly identified, query the provider.
