Healthcare providers often lose valuable time to scheduling gaps, missed visits, documentation issues, and constant patient follow-ups, taking focus away from patient care. That’s where I come in.
I am a Medical Virtual Assistant and Home Health Scheduler with 4+ years of hands-on experience supporting clinics, solo practitioners, telehealth providers, and home health agencies across the United States. I have worked with 12+ providers across 3 clinics and 11 locations, helping streamline daily operations, improve scheduling accuracy, and maintain HIPAA-compliant workflows.
Medical Virtual Assistance & Home Health Scheduling
I manage patient and staff schedules with precision, coordinating clinic appointments, tele-visits, follow-ups, and home health visits. I assign clinicians to patients based on availability, location, and care needs, adjust schedules for call-outs or urgent visits, and send appointment reminders to reduce no-shows and delays.
I am experienced with eClinicalWorks, Tebra, Alora for Home Care, DrChrono, and Athenahealth, and I adapt quickly to new systems.
Patient Coordination & Communication
I handle inbound and outbound patient calls professionally, address concerns with empathy, and follow up on appointments, referrals, lab results, and provider messages. I initiate and document telephone encounters in eClinicalWorks to ensure clear communication between patients and providers.
Medical Records & Compliance
I maintain accurate medical records while strictly adhering to HIPAA Privacy & Security standards. I securely manage referrals, record transfers, PHI access, and BAAs when required.
Medication Refills & Pharmacy Coordination
I assist with prescription refill requests by reviewing medication history, confirming dosages, relaying details to providers for approval, and following up with pharmacies to ensure timely processing.
New Patient Intake & Insurance Verification
I register new patients, accurately enter demographics and insurance details, verify eligibility, check authorization requirements, and assist patients with insurance-related questions prior to referrals.
Workload & Schedule Optimization
I help balance provider workloads by coordinating schedules efficiently, reducing burnout while maintaining quality patient care.
I hold five relevant certifications, including HIPAA Privacy & Security (Omnibus Rule), and I am highly adaptable, reliable, and detail-oriented.
What you can expect from me
✔️ Empathetic and patient-centered communication
✔️ Clear, professional verbal and written communication
✔️ Strong problem-solving and critical thinking
✔️ Flexibility with tools, workflows, and schedules
✔️ Collaborative teamwork with providers and staff
I would love the opportunity to support your organization by improving scheduling accuracy, patient communication, and overall operational efficiency. I’m confident my experience as a Medical Virtual Assistant and Home Health Scheduler will be a strong asset to your team.
