ICD-10 Code D73.9 – Disease of spleen, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73.9 – Disease of spleen, unspecified
What it is
D73.9 is used for a spleen disorder when the record identifies splenic disease but does not specify the exact condition. It signals an abnormality of the spleen without naming a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include splenic enlargement, pain or fullness in the left upper abdomen, or an incidental abnormal spleen finding on imaging.
When to use this code
Use D73.9 when the provider documents a spleen disease but does not define it further, such as “spleen disorder” or “unspecified splenic disease.” It also fits when imaging or examination shows a spleen abnormality and no clearer diagnosis is recorded. Check documentation before assigning a more specific code.
Do not use for
Do not use this code when the chart gives a specific splenic diagnosis, such as splenomegaly, infarction, or rupture. Avoid it for postoperative or traumatic spleen conditions unless the provider documents an unspecified disease.
Coding tip
Query for specificity whenever the spleen problem is described vaguely, because a more exact code may be available.
