Independent Doctor

Cornerstone Orthopaedic Trauma Associates partners with Independent Doctors of Idaho (IDID). This allows us to choose the highest quality of care and affordable options for our patients.


As independent providers, we have additional freedoms to diagnose and treat patients without the confines of any particular hospital system. Patients and doctors have greater freedom and control of health care decisions, while avoiding potentially conflicting interests. Choice leads to the most affordable care with personalized treatment. IDID offers additional cost saving choices.
