S79.119A — Salter-Harris Type I physeal fracture of lower end of unspecified femur, initial encounter for closed fracture
Is S79.119A billable?
Yes, but S79.119A will trip a Medicare edit. S79.119A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S79.119A 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.
