ICD-10 Code C84.76 – Anaplastic large cell lymphoma, ALK-negative, intrapelvic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C84.76 – Anaplastic large cell lymphoma, ALK-negative, intrapelvic lymph nodes
What it is
This code identifies anaplastic large cell lymphoma that is ALK-negative and involves the intrapelvic lymph nodes. Use it when documentation specifies this lymphoma subtype and pelvic nodal site.
Clinical signs
Clinical features vary; refer to documentation. Typical lymphoma findings may include enlarged lymph nodes, systemic “B” symptoms, or mass effect related to pelvic nodal disease.
When to use this code
Use this code when the provider documents ALK-negative anaplastic large cell lymphoma with involvement of intrapelvic lymph nodes. It may also apply when pathology or oncology notes clearly localize the disease to pelvic nodes. If the site or ALK status is not stated, check documentation before coding.
Do not use for
Do not use this code for ALK-positive anaplastic large cell lymphoma or for lymphoma in other nodal regions. If the record only says “lymphoma” without subtype and site, do not assume C84.76.
Coding tip
Verify both the ALK-negative status and the intrapelvic lymph node location in the final diagnostic statement.
