2027 ICD-10-CM Diagnosis Code O67.0Intrapartum hemorrhage with coagulation defect
ICD-10-CM Codes›O00-O9A›O60-O77›O67
- Billable — Valid for Submission
- MCC — Major Complication or Comorbidity
- Not Chronic
O67.0 is a billable ICD-10-CM diagnosis code for intrapartum hemorrhage with coagulation defect. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 998. 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 263 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 abnormal fibrinolysis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complications specified during childbirth and Hemorrhage after first trimester.

Patient EducationClinical
Bleeding Disorders
Normally, if you get hurt, your body forms a blood clot to stop the bleeding. For blood to clot, your body needs cells called platelets and proteins known as clotting factors. If you have a bleeding disorder, you either do not have enough platelets or clotting factors or they don't work the way they should.
