Impact of depressive symptoms on direct medical cost among medicare recipients with knee osteoarthritis

Osteoarthritis CartilagePublished Retrospective cohort study

Authors' conclusion

While over one quarter of Medicare beneficiaries with KOA self-reported depressive symptoms, only 6% received billable medical services. The presence of depressive symptoms led to higher direct medical costs, even among those who did not receive depression-related billable services.
