O14.93 — Unspecified pre-eclampsia, third trimester
Is O14.93 billable?
Yes, but O14.93 is an unspecified code. O14.93 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O14.93 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 O14.93 — the more specific alternatives are listed below.

Which MS-DRGs does O14.93 group to?
