ICD-10 Code C95.90 – Leukemia, unspecified not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C95.90 – Leukemia, unspecified not having achieved remission
What it is
This code identifies leukemia when the type is not specified and the patient has not achieved remission. Use it for a documented leukemia diagnosis without clearer subtype detail.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include signs of marrow failure, such as anemia, infection, or bleeding, but the exact presentation depends on the leukemia type.
When to use this code
Use C95.90 when the record states leukemia but does not name a specific leukemia subtype. It also applies when the provider documents that the disease has not achieved remission and no more specific code is supported.
If later documentation identifies the exact leukemia type or remission status, you should code that more specific information instead. Check documentation for whether the diagnosis is current, historical, or ruled out.
Do not use for
Do not use this code if the leukemia subtype is documented, such as acute or chronic forms with a specific lineage. Do not use it for remission cases or when the diagnosis is only suspected.
Coding tip
Query for the leukemia subtype and remission status whenever the note says only “leukemia.”
