ICD-10 Code C84.60 – Anaplastic large cell lymphoma, ALK-positive, unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C84.60 – Anaplastic large cell lymphoma, ALK-positive, unspecified site
What it is
C84.60 identifies anaplastic large cell lymphoma that is ALK-positive when the site is not specified. Use it for a documented ALK-positive T-cell lymphoma diagnosis without a more exact anatomic location.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe a lymphoma with enlarged lymph nodes or other involved tissue, and pathology confirming anaplastic large cell lymphoma with ALK positivity.
When to use this code
Use this code when the provider documents ALK-positive anaplastic large cell lymphoma and does not specify the primary or involved site. It also fits when the chart confirms the diagnosis but location details are unavailable. If a more specific site is later documented, code that instead.
Do not use for
Do not use this code for ALK-negative anaplastic large cell lymphoma or for other lymphoma subtypes. If the documentation names a specific site, check whether a more precise code applies.
Coding tip
Confirm both ALK status and site in the pathology or oncology note before assigning C84.60.
