- Not Chronic
D78.89 is a billable ICD-10-CM diagnosis code for other postprocedural complications of the spleen. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 919 through 921. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 18 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative complications of the spleen.
