ICD-10 Code D73.3 – Abscess of spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73.3 – Abscess of spleen
What it is
D73.3 identifies a localized collection of pus in the spleen. Use it when documentation states a splenic abscess, usually from infection within splenic tissue.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include fever, left upper quadrant pain, and tenderness, with imaging often used to confirm a splenic abscess.
When to use this code
Use D73.3 when the provider documents an abscess of the spleen, whether primary or secondary to another infection. It may also apply when the record describes a splenic abscess confirmed by imaging or operative findings. Check documentation for the exact diagnosis wording.
Do not use for
Do not use this code for nonspecific splenomegaly, splenic cysts, or traumatic splenic injury without abscess. If the record only says “splenic lesion” or “mass,” check documentation.
Coding tip
Code D73.3 only when the spleen infection is clearly documented as an abscess, not merely suspected.
