I75.029 — Atheroembolism of unspecified lower extremity
Is I75.029 billable?
Yes, but I75.029 will trip a Medicare edit. I75.029 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists I75.029 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.
