ICD-10 Code D73.89 – Other diseases of spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73.89 – Other diseases of spleen
What it is
D73.89 identifies spleen disorders that do not fit a more specific ICD-10 category. Use it for documented spleen disease when the record names an “other” splenic condition rather than a defined injury, enlargement, or blood disorder.
Clinical signs
Clinical features vary; refer to documentation. Findings may include left upper quadrant discomfort, splenic tenderness, or imaging evidence of an abnormal spleen, but the code is based on the documented diagnosis, not on symptoms alone.
When to use this code
Use D73.89 when the provider documents another specific disease of the spleen and no more precise code is available. It is appropriate for charted splenic abnormalities that are not classified elsewhere in ICD-10-CM. Check documentation carefully if the note only says “splenic lesion,” “spleen disorder,” or similar nonspecific language.
Do not use for
Do not use this code for traumatic spleen injury, splenomegaly, or hematologic conditions with a separate diagnosis code. If the record supports a more specific splenic disorder, code that condition instead.
Coding tip
Query the provider when the spleen diagnosis is vague, because D73.89 is a residual category and should not replace a more specific documented code.
