O90.41 is a billable ICD-10-CM diagnosis code for hepatorenal syndrome following labor and delivery. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 769, 776. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 222 closely related codes. The code is restricted by the Medicare Code Editor to maternity cases (age 9 through 64). Coders also document this condition as hepatorenal syndrome. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Acute and unspecified renal failure, Complications specified during the puerperium, and Other specified and unspecified liver disease.

Patient EducationClinical

Kidney Failure

Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise.
