Is Y36.891S billable?

However, Y36.891S 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 Y36.891S — the more specific alternatives are listed below.
