ICD-10 Code D73.5 – Infarction of spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73.5 – Infarction of spleen
What it is
D73.5 identifies an infarction of the spleen, meaning splenic tissue has lost blood supply and become ischemic or necrotic. Use it for the condition itself, not for the underlying cause.
Clinical signs
Clinical features vary; refer to documentation. Commonly, notes describe left upper quadrant or left flank pain, tenderness, and imaging evidence of splenic ischemia or wedge-shaped infarct.
When to use this code
Use D73.5 when the provider documents splenic infarction, splenic ischemia, or infarct of the spleen. It may appear on imaging reports, discharge summaries, or problem lists when the diagnosis is confirmed.
If the record also identifies a cause, such as embolic disease or sickle cell-related infarction, code the documented cause separately when instructed by the record and guidelines.
Do not use for
Do not use this code for splenic rupture, abscess, cyst, or generalized abdominal pain without a documented infarction. Check documentation if the note is unclear.
Coding tip
Code D73.5 only when splenic infarction is explicitly documented or clearly confirmed by imaging or provider assessment.
