S75.909A — Unspecified injury of unspecified blood vessel at hip and thigh level, unspecified leg, initial encounter
Is S75.909A billable?
Yes, but S75.909A will trip a Medicare edit. S75.909A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S75.909A under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.
