S49.019A — Salter-Harris Type I physeal fracture of upper end of humerus, unspecified arm, initial encounter for closed fracture
Is S49.019A billable?
Yes, but S49.019A will trip a Medicare edit. S49.019A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S49.019A 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.
