O20.9 — Hemorrhage in early pregnancy, unspecified
Is O20.9 billable?
Yes, but O20.9 is an unspecified code. O20.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O20.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting O20.9 — the more specific alternatives are listed below.

Which MS-DRGs does O20.9 group to?
O20.9 sits in MDC 14 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 817Other Antepartum Diagnoses with O.R. Procedures with MCCsurgical
- 818Other Antepartum Diagnoses with O.R. Procedures with CCsurgical
- 819Other Antepartum Diagnoses with O.R. Procedures without CC/MCCsurgical
As a secondary diagnosis, O20.9 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
