ICD-10 Code C92.Z – Other myeloid leukemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.Z – Other myeloid leukemia
What it is
C92.Z identifies a myeloid leukemia that does not fit a more specific ICD-10 category. Use it for documented myeloid leukemia when the record names an unspecified or other type.
Clinical signs
Clinical features vary; refer to documentation. Patients with myeloid leukemia may have abnormal blood counts, fatigue, infections, bruising, or bleeding, but you should code based on the documented diagnosis.
When to use this code
Use C92.Z when the clinician documents “other myeloid leukemia” or a comparable diagnosis that is not described by a more specific code. It may also apply when the subtype is known to be myeloid but not otherwise classified in the chart.
If the record later specifies a different leukemia subtype, update the code to match the final documentation. Check documentation carefully when pathology or oncology notes provide a more exact diagnosis.
Do not use for
Do not use this code for acute lymphoblastic leukemia, chronic lymphocytic leukemia, or other non-myeloid leukemias. If the type is unspecified, verify whether a different unspecified leukemia code is more appropriate.
Coding tip
Code only what the provider documents, and query for the exact leukemia subtype if “other myeloid leukemia” is unclear.
