ICD-10 Code C81.2A – Mixed cellularity Hodgkin lymphoma, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.2A – Mixed cellularity Hodgkin lymphoma, in remission
What it is
This code identifies a history of mixed cellularity Hodgkin lymphoma that is currently in remission. Use it when the malignancy is no longer active, but the diagnosis remains clinically relevant.
Clinical signs
Clinical features vary; refer to documentation. Mixed cellularity Hodgkin lymphoma is a subtype of Hodgkin lymphoma, and remission means there is no evidence of active disease at the time of the encounter.
When to use this code
Use this code when the provider documents mixed cellularity Hodgkin lymphoma as in remission, inactive, or without evidence of disease. It may apply during follow-up visits, surveillance care, or when the past lymphoma remains relevant to current management. Check documentation if the remission status is unclear.
Do not use for
Do not use this code for active mixed cellularity Hodgkin lymphoma or for unspecified Hodgkin lymphoma. If the record does not clearly state remission, do not assume it.
Coding tip
Confirm both the lymphoma subtype and remission status in the provider note before assigning C81.2A.
