O08.9 — Unspecified complication following an ectopic and molar pregnancy

BillableUnspecifiedCC

Is O08.9 billable?

Yes, but O08.9 is an unspecified code. O08.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O08.9 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 O08.9 — the more specific alternatives are listed below.

Which MS-DRGs does O08.9 group to?

O08.9 sits in MDC 14 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
