A grievance is a written complaint or concern about a non-appealable issue regarding a perceived failure by any member of the health care delivery team. Any TRICARE civilian or military provider, TRICARE beneficiary, sponsor, parent or guardian or other representative of an eligible beneficiary may file a grievance.

International SOS as the TRICARE Overseas Program (TOP) Contractor is responsible for investigating and resolving all grievances. Grievances are generally resolved within 60 days of receipt. Following resolution, International SOS will notify the party submitting the grievance that the review is complete.

Grievances may include such issues as:
  • The quality of health care or services (e.g., accessibility, appropriateness, level of care, continuity, timeliness of care)
  • The demeanor or behavior of providers and their staffs
  • The performance of any part of the health care delivery system
  • Practices related to patient safety
