Pathology-Led Test Order Review & Coordination

The designated Pathway Pathologist reviews each order for alignment with applicable Pathway Guidelines and coordinates testing with an appropriately aligned participating laboratory. This review is a standard component of the Pathway and does not require a separate consultation request.

If the review identifies a clinical concern, the Pathologist contacts the Treating Provider for interprofessional consultation before testing proceeds. No ordered test may be added, removed, or substituted without the Treating Provider's prior authorization.

Continuity of Clinical Coordination

The designated Pathologist remains the Treating Provider's central point of contact throughout the Pathway, providing comprehensive interpretation of laboratory findings and coordinating neurologic subspecialty consultation, complex case review, and preparation of the Clinical Integration Consultation & Report when requested.

Optional Pre-Test Interprofessional Consultation

Treating Providers may also request a patient-specific consultation before ordering laboratory testing. These consultations may address:

• Selection and clinical appropriateness of available biomarker tests.
• Diagnostic considerations based on the patient's injury history, symptoms, clinical presentation, and available records.
• The intended clinical use, capabilities, and limitations of specific assays.
• Additional diagnostic evaluation or specialist consultation when clinically appropriate.
• Other patient-specific questions concerning testing and Pathway services.

The Treating Provider retains responsibility for determining medical necessity and authorizing laboratory orders.

Pathology / interprofessional consultations are professional physician services provided and billed by the participating pathology practice, as applicable.

Provided by: Pathway Pathologist & Consulting Subspecialists

When requested by the Treating Provider, the patient's designated Primary Pathway Clinician (PPC) coordinates a multidisciplinary clinical case review involving one or more appropriately qualified consulting specialists, selected according to the patient's clinical needs. These may include neurointensivists, neurologists, and other specialists with expertise relevant to the patient's injury, diagnostic findings, and clinical presentation.

The PPC coordinates the integration of the Pathology Interpretive Report and relevant diagnostic findings with the patient's clinical history, neurologic presentation, treatment records, and clinical course. Each participating specialist contributes independent clinical expertise, findings, and recommendations within their respective scope of practice.

These contributions are consolidated into a single, comprehensive Clinical Integration Consultation & Report, providing the Treating Provider with a coordinated, multidisciplinary clinical assessment and patient-specific recommendations to support diagnostic evaluation, treatment planning, and ongoing care decisions. Each consulting physician signs their respective contributions, and the PPC performs the final review, signs, and delivers the integrated report to the Treating Provider.

The consultation supports, but does not replace, the Treating Provider's independent clinical judgment and responsibility for the patient's medical management.
