Meet Your Advocate

Abby Trubey, MSN, RN

I’m a Master’s-prepared Registered Nurse specializing in Utilization Review and Denial Management. With advanced clinical training and a deep understanding of payer requirements, I help healthcare organizations ensure that patient care is both medically necessary and compliant with insurance and regulatory standards.

Throughout my career, I’ve combined my nursing background with analytical and systems-based thinking to review medical records, assess medical necessity, and prevent costly denials. I work closely with providers, case managers, and insurance representatives to align clinical care with payer expectations — protecting both quality and reimbursement.

My approach is rooted in evidence-based practice, attention to detail, and a genuine commitment to supporting providers and patients alike. I believe in bridging the gap between clinical care and coverage criteria so healthcare professionals can focus on what truly matters: delivering excellent care.

“My mission is to bring clinical clarity, integrity, and advocacy to every review — ensuring care is covered, compliant, and compassionate.”
