S25.519A — Laceration of intercostal blood vessels, unspecified side, initial encounter
Is S25.519A billable?
Yes, but S25.519A will trip a Medicare edit. S25.519A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S25.519A 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.
