ICD-10 Code D75.8 – Other specified diseases of blood and blood-forming organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D75.8 – Other specified diseases of blood and blood-forming organs
What it is
D75.8 is used for a blood or blood-forming organ disorder that does not fit a more specific ICD-10-CM category. It is a catch-all code for documented conditions affecting the hematologic system.
Clinical signs
Clinical features vary; refer to documentation. Findings may include unexplained abnormalities involving blood cells, spleen, or related blood-forming tissues, but the exact diagnosis should be stated in the record.
When to use this code
Use D75.8 when the provider documents a specific disorder of blood or blood-forming organs that has no dedicated code. It may apply when the condition is named clearly, but the index or tabular list points to this unspecified category. If the chart only says “blood disorder,” check documentation for a more precise diagnosis.
Do not use for
Do not use this code when a more specific hematologic diagnosis is documented, such as a defined anemia, coagulation disorder, or malignant blood disease. Avoid it for symptoms alone or for unclear notes that need clarification.
Coding tip
Before assigning D75.8, confirm the provider’s exact wording and look for a more specific code first.
