R19.7 — Diarrhea, unspecified

BillableUnspecified

Is R19.7 billable?

Yes, but R19.7 is an unspecified code. R19.7 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, R19.7 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 R19.7 — the more specific alternatives are listed below.

  • neonatal diarrhea (P78.3)
  • psychogenic diarrhea (F45.8)
