Complaints & Grievances

Effective Date: June 5, 2026 · Last Updated: June 5, 2026 · Version: 1.0

If you have a complaint about Atlas Managed Care, such as the way you were treated, a service you received, a determination on your case, or our privacy practices, this page tells you exactly how to raise it, what we'll do about it, and where else you can go for help.

1. Our Commitment

Atlas Managed Care takes every complaint seriously. We commit to:

Our complaint process aligns with URAC consumer-complaint standards (Workers' Compensation Utilization Management Standard CPE 2-3) and California Division of Workers' Compensation ("DWC") expectations under California Labor Code § 4610 and 8 CCR §§ 9792.6 – 9792.9.5.

2. Types of Complaints We Handle

2.1 Service Complaints

Concerns about how you were treated by an Atlas representative, response times, communication, professionalism, or access to services.

2.2 Utilization Review Complaints

Concerns about the conduct of a utilization review, the timeliness of a determination, the qualifications of a reviewer, or the process by which a determination was made. Note: utilization review determinations themselves (approval, modification, or denial of treatment) are subject to a separate appeal and Independent Medical Review process under California Labor Code § 4610.5. See Section 6.

2.3 Privacy Complaints

Concerns about how Atlas has used or disclosed your Protected Health Information ("PHI"). See our HIPAA Notice of Privacy Practices for the full process.

If you cannot or do not wish to provide all this information, we will still review your complaint.

4. What Happens After You File

  1. Acknowledgment within 5 business days. We confirm receipt of your complaint in writing (email, letter, or both, per your preference), assign it a tracking number, and identify the staff member responsible for investigating.
  2. Investigation within 30 calendar days.

Expedited investigation (within 72 hours) is available where there is a serious, imminent threat to health or safety.
  3. Written resolution within 30 calendar days of acknowledgment. You will receive a written response explaining the findings of our investigation, any corrective action taken, and your right to seek further review (Section 5 and Section 6 below). If we need additional time, we will notify you in writing and provide an updated expected response date, not to exceed an additional 30 calendar days.
  4. Tracking and trending. Every complaint is logged in our Complaints Register and reviewed in our quarterly Quality Improvement meetings. Trends inform corrective action and training.

5. If You Are Not Satisfied With Our Response

6. Utilization Review: Separate Appeal and IMR Process

If your complaint concerns the substantive outcome of a utilization review determination (the decision to approve, modify, or deny requested treatment), California law provides a separate appeal and Independent Medical Review ("IMR") process.

For details, see the IMR information mailed with your determination letter, or contact the DWC Information and Assistance Unit (Section 7.1).
