S68.429A — Partial traumatic amputation of unspecified hand at wrist level, initial encounter
Is S68.429A billable?
Yes, but S68.429A will trip a Medicare edit. S68.429A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S68.429A 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.
