T81.599D — Other complications of foreign body accidentally left in body following unspecified procedure, subsequent encounter

BillableUnspecified

Is T81.599D billable?

Yes, but T81.599D is an unspecified code. T81.599D is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T81.599D 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 T81.599D — the more specific alternatives are listed below.
