ICD-10 Code D73.8 – Other diseases of spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73.8 – Other diseases of spleen
What it is
D73.8 identifies spleen disorders that do not fit a more specific ICD-10-CM code. Use it for documented splenic conditions when the record names an “other” spleen disease without a better category.
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 noted on imaging or exam.
When to use this code
Use D73.8 when the provider documents a spleen disorder that is not otherwise classified and no more specific code applies. It is appropriate for nonspecific splenic disease descriptions, unusual structural abnormalities, or other documented spleen conditions. If the record supports a different spleen diagnosis, code that condition instead.
Do not use for
Do not use D73.8 when the diagnosis is a specific spleen disorder with its own code, such as splenic rupture or infarction. Check documentation if the chart only states splenomegaly, hypersplenism, or another named condition.
Coding tip
Query the provider when the spleen diagnosis is vague, because a more specific code may be available.
