L98.A395 — Non-pressure chronic ulcer of unspecified hand with muscle involvement without evidence of necrosis

BillableUnspecifiedCC

Is L98.A395 billable?

Yes, but L98.A395 will trip a Medicare edit. L98.A395 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists L98.A395 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.
