S92.209K — Fracture of unspecified tarsal bone(s) of unspecified foot, subsequent encounter for fracture with nonunion

BillableUnspecifiedCC

Is S92.209K billable?

Yes, but S92.209K will trip a Medicare edit. S92.209K is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S92.209K 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 S92.209K group to?

  • 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
  • 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
  • 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical

As a secondary diagnosis, S92.209K is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
