L98.A394 — Non-pressure chronic ulcer of unspecified hand with necrosis of bone

BillableUnspecifiedCC

Is L98.A394 billable?

Yes, but L98.A394 will trip a Medicare edit. L98.A394 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists L98.A394 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.

Which MS-DRGs does L98.A394 group to?
