ICD-10 Code D73.2 – Chronic congestive splenomegaly (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D73.2 – Chronic congestive splenomegaly
What it is
D73.2 identifies chronic enlargement of the spleen caused by long-standing venous congestion. Use it when documentation states congestive splenomegaly or a similar chronic congestive splenic condition.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the spleen is enlarged on exam or imaging, with findings consistent with chronic congestion rather than an acute splenic process.
When to use this code
Use D73.2 when the record specifically documents chronic congestive splenomegaly. It may apply when the provider describes splenic enlargement due to chronic passive congestion or portal venous congestion. Check documentation if the cause is not clearly stated.
Do not use for
Do not use this code for splenomegaly without a documented congestive or chronic cause. Do not use it for acute splenic enlargement, splenic injury, or other specified spleen disorders.
Coding tip
Code the documented spleen condition only when the provider links it to chronic congestion; otherwise, query or choose a more specific spleen code.
