ICD-10-CM Codes›O00-O9A›O00-O08›O03
- Billable — Valid for Submission
- MCC — Major Complication or Comorbidity
- Not Chronic
O03.32 is a billable ICD-10-CM diagnosis code for renal failure following incomplete spontaneous abortion. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 770, 779. 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 311 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 miscarriage complicated by renal failure. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Spontaneous abortion and complications of spontaneous abortion.
