ICD-10 Code D75 – Other and unspecified diseases of blood and blood-forming organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D75 – Other and unspecified diseases of blood and blood-forming organs
What it is
D75 covers disorders of the blood and blood-forming organs that do not fit a more specific ICD-10 code. Use it for documented conditions in this category when the record does not identify a narrower diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormalities involving blood cell production, blood cell counts, or related hematologic disorders, but the exact presentation depends on the underlying condition.
When to use this code
Use D75 when the provider documents an “other” or unspecified disease of blood or blood-forming organs and no more specific code is available. It is appropriate when the chart confirms a hematologic disorder but does not name a precise subtype. If the diagnosis is incomplete or unclear, check documentation before coding.
Do not use for
Do not use D75 if the record supports a specific blood disorder with its own code, such as a defined anemia, coagulopathy, or malignancy. Do not code it for normal lab variation or an unconfirmed abnormal result.
Coding tip
Look for the provider’s exact hematologic diagnosis first; use D75 only when the documentation truly remains nonspecific.
