ICD-10 Code D75.89 – Other specified diseases of blood and blood-forming organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D75.89 – Other specified diseases of blood and blood-forming organs
What it is
This code covers blood or blood-forming organ disorders that do not fit a more specific ICD-10 category. Use it when the record names a defined condition but no exact code is available.
Clinical signs
Clinical features vary; refer to documentation. Records may describe abnormal blood cell findings, marrow-related disorders, or other hematologic abnormalities without a more specific diagnosis.
When to use this code
Use D75.89 when the clinician documents a specified disorder of blood or blood-forming organs and no narrower code applies. It is appropriate when the diagnosis is clear, but the chart does not support a more specific hematology code. Check documentation for the exact condition named.
Do not use for
Do not use this code when the record supports a specific blood disorder with its own ICD-10 code. Also avoid it for nonspecific abnormal laboratory findings alone unless the provider documents a qualifying diagnosis.
Coding tip
Match the code to the provider’s exact wording and confirm that a more specific hematologic diagnosis is not documented elsewhere.
