O36.4XX0 — Maternal care for intrauterine death, not applicable or unspecified
Is O36.4XX0 billable?
Yes, but O36.4XX0 is an unspecified code. O36.4XX0 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O36.4XX0 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 O36.4XX0.
