ICD-10 Code D73 – Diseases of spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73 – Diseases of spleen
What it is
D73 is the ICD-10-CM category for disorders of the spleen. Use it when the record documents a spleen condition, but no more specific code is available.
Clinical signs
Clinical features vary; refer to documentation. Spleen disorders may be noted with splenomegaly, pain or fullness in the left upper abdomen, or abnormal findings on exam or imaging.
When to use this code
Use D73 when the provider documents a spleen disease without naming a more specific diagnosis. It is appropriate for nonspecific spleen conditions, or when the chart only states “disease of spleen.” Check documentation for the exact condition.
Do not use for
Do not use D73 if the record identifies a specific spleen diagnosis that has its own code. Do not code it for symptoms alone or for routine imaging findings without a documented disorder.
Coding tip
Always code the most specific spleen diagnosis documented; use D73 only when the provider’s wording remains nonspecific.
