ICD-10 Code C81.9A – Hodgkin lymphoma, unspecified, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.9A – Hodgkin lymphoma, unspecified, in remission
What it is
This code identifies a history of Hodgkin lymphoma that is currently in remission, with the subtype not specified. Use it when the record clearly states remission and does not name a more specific Hodgkin lymphoma type.
Clinical signs
Clinical features vary; refer to documentation. In remission, the chart should support prior Hodgkin lymphoma and indicate no active disease, often based on oncology follow-up, imaging, or pathology review.
When to use this code
Use this code when the provider documents Hodgkin lymphoma, unspecified, as being in remission. It is appropriate for follow-up visits, surveillance care, and problem lists when the condition remains clinically relevant but inactive. Check documentation if the remission status is unclear.
Do not use for
Do not use this code for active Hodgkin lymphoma or when the subtype is specified elsewhere in the record. Do not assign it if the chart only notes a history of lymphoma without stating remission.
Coding tip
Confirm both the lymphoma diagnosis and the remission status in the provider note before coding.
