ICD-10 Code D75.9 – Disease of blood and blood-forming organs, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D75.9 – Disease of blood and blood-forming organs, unspecified
What it is
D75.9 is used for a blood or blood-forming organ disorder when the provider documents the condition without a more specific diagnosis. It is a nonspecific code for hematologic disease.
Clinical signs
Clinical features vary; refer to documentation. Patients may have nonspecific hematologic abnormalities, but the record must support a disorder of blood or blood-forming organs rather than a symptom alone.
When to use this code
Use D75.9 when the chart clearly identifies a disease of the blood or blood-forming organs, but the exact type is not stated. It can also apply when the condition is documented as unspecified after evaluation. Do not guess a more specific code.
Do not use for
Do not use this code for isolated symptoms, abnormal test results, or conditions with a documented specific hematologic diagnosis. Check documentation if the provider names a more precise disorder.
Coding tip
Code D75.9 only after confirming the provider has documented an unspecified blood or blood-forming organ disease.
