I70.393 — Other atherosclerosis of unspecified type of bypass graft(s) of the extremities, bilateral legs
Is I70.393 billable?
Yes, but I70.393 is an unspecified code. I70.393 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I70.393 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 I70.393 — the more specific alternatives are listed below.
