M84.753P — Incomplete atypical femoral fracture, unspecified leg, subsequent encounter for fracture with malunion
Is M84.753P billable?
Yes, but M84.753P will trip a Medicare edit. M84.753P is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists M84.753P 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.
