T50.914S — Poisoning by multiple unspecified drugs, medicaments and biological substances, undetermined, sequela
Is T50.914S billable?
Yes, but T50.914S is an unspecified code. T50.914S is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T50.914S 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 T50.914S.
