T75.1XXA — Unspecified effects of drowning and nonfatal submersion, initial encounter
Is T75.1XXA billable?
Yes, but T75.1XXA is an unspecified code. T75.1XXA is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T75.1XXA 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 T75.1XXA.
