ICD-10 Code C84.7B – Anaplastic large cell lymphoma, ALK-negative, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C84.7B – Anaplastic large cell lymphoma, ALK-negative, in remission
What it is
This code identifies a history of ALK-negative anaplastic large cell lymphoma that is currently in remission. Use it when the lymphoma is no longer active, but the diagnosis remains clinically relevant.
Clinical signs
Clinical features vary; refer to documentation. Prior records may show nodal or extranodal lymphoma with abnormal T-cell findings and ALK-negative pathology, but remission means there is no current active disease noted.
When to use this code
Use this code when the provider documents ALK-negative anaplastic large cell lymphoma as being in remission, including follow-up visits after treatment. It supports coding of ongoing surveillance or survivorship care when active lymphoma is not present. Check documentation if remission status is unclear.
Do not use for
Do not use this code for active lymphoma, suspected recurrence, or unspecified remission status. If the record does not clearly state ALK-negative disease in remission, check documentation.
Coding tip
Code remission only when the provider explicitly documents it, and verify that ALK-negative status is also stated.
