M96.669Fracture of femur following insertion of orthopedic implant, joint prosthesis, or bone plate, unspecified leg

BillableUnspecifiedCC

Is M96.669 billable?

Yes, but M96.669 will trip a Medicare edit. M96.669 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists M96.669 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.

What Medicare edits apply to M96.669?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name M96.669 directly.

Unspecified — a laterality-specific code exists — MCE edit 20

A code specifying laterality (right, left or bilateral) exists in the same family. CMS holds that there are very limited circumstances in which laterality cannot be documented.

Which MS-DRGs does M96.669 group to?

M96.669 sits in MDC 08 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 559Aftercare, Musculoskeletal System and Connective Tissue with MCCmedical
  • 560Aftercare, Musculoskeletal System and Connective Tissue with CCmedical
  • 561Aftercare, Musculoskeletal System and Connective Tissue without CC/MCCmedical

As a secondary diagnosis, M96.669 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
