ICD-10 Code C84.67 – Anaplastic large cell lymphoma, ALK-positive, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C84.67 – Anaplastic large cell lymphoma, ALK-positive, spleen
What it is
This code identifies anaplastic large cell lymphoma that is ALK-positive and involves the spleen. Use it when the diagnosis specifically documents splenic involvement.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe lymphoma findings such as splenic enlargement, systemic “B” symptoms, or abnormal imaging and pathology consistent with ALK-positive anaplastic large cell lymphoma.
When to use this code
Use C84.67 when the provider documents ALK-positive anaplastic large cell lymphoma with splenic involvement as the site or manifestation. It may appear on pathology, oncology, or discharge documentation. If the spleen is not clearly specified, check documentation before assigning this code.
Do not use for
Do not use this code for ALK-negative disease, other lymphoma subtypes, or nonspecific lymphoma without splenic involvement. Check documentation if the record only states “large cell lymphoma” or “lymphoma of spleen.”
Coding tip
Code the documented histology and ALK status separately from the anatomic site, and confirm that the spleen is explicitly named.
