ICD-10 Code C88.01 – Waldenström Macroglobulinemia, in Remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C88.01 – Waldenström macroglobulinemia, in remission
What it is
C88.01 identifies Waldenström macroglobulinemia that is documented as being in remission. Use it when the underlying lymphoplasmacytic lymphoma has responded and the record states remission status.
Clinical signs
Clinical features vary; refer to documentation. Waldenström macroglobulinemia is typically associated with an IgM-producing lymphoplasmacytic disorder, and remission means the active disease is no longer clinically evident.
When to use this code
Use this code when the provider explicitly documents Waldenström macroglobulinemia in remission, including partial or complete remission if stated in the record. It is appropriate for follow-up visits, surveillance, or history review when the condition remains relevant but inactive. Check documentation if remission status is unclear.
Do not use for
Do not use C88.01 if the chart does not clearly state remission, or if the disease is active, relapsed, or refractory. If the diagnosis is uncertain, check documentation and code the confirmed condition only.
Coding tip
Always link the code to explicit remission wording in the provider note; do not infer remission from stable labs or routine follow-up alone.
