ICD-10 Code C95.91 – Leukemia, unspecified, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C95.91 – Leukemia, unspecified, in remission
What it is
This code identifies a history of leukemia that is currently in remission, but the specific leukemia type is not documented. Use it when the record states remission without naming the leukemia subtype.
Clinical signs
Clinical features vary; refer to documentation. In remission, active leukemia findings are typically absent or improved, and the chart should support prior leukemia with current remission status.
When to use this code
Use C95.91 when the provider documents “leukemia, unspecified, in remission” or similar wording. It fits follow-up visits, surveillance, or problem-list entries when the exact leukemia type is not available in the note.
If the record later identifies a specific leukemia, code that condition instead. Check documentation for whether remission is complete, active disease has returned, or the diagnosis is only historical.
Do not use for
Do not use this code for active leukemia, relapse, or remission of a specified leukemia subtype. Do not assign it when the chart only says “history of leukemia” without current remission status.
Coding tip
Confirm both “unspecified” and “in remission” are documented before assigning C95.91.
