T23.369A — Burn of third degree of back of unspecified hand, initial encounter
Is T23.369A billable?
Yes, but T23.369A will trip a Medicare edit. T23.369A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists T23.369A 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.
