Is S42.343G billable?

Yes, but S42.343G is an unspecified code. S42.343G is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S42.343G 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 S42.343G — the more specific alternatives are listed below.
