ICD-10 Code D78.3 – Postprocedural hematoma and seroma of the spleen following a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D78.3 – Postprocedural hematoma and seroma of the spleen following a procedure
What it is
D78.3 identifies a hematoma or seroma involving the spleen that develops after a procedure. Use it when documentation shows a postprocedural collection of blood or serous fluid in the splenic area.
Clinical signs
Clinical features vary; refer to documentation. Findings may include postoperative splenic pain, localized swelling, or imaging evidence of a fluid or blood collection after splenic intervention.
When to use this code
Use this code when the provider documents a splenic hematoma or seroma as a complication of surgery or another procedure. It fits postoperative or post-intervention records that clearly link the collection to the procedure. Check documentation if the site or cause is unclear.
Do not use for
Do not use it for traumatic splenic hematoma, spontaneous splenic bleeding, or collections not tied to a procedure. If the record does not specify the spleen or a postprocedural cause, check documentation.
Coding tip
Verify that the note states both the splenic location and the procedure-related cause before assigning D78.3.
