“The outbound calling program alone was a game changer. We never thought to do that systematically.”

This 3-location Raleigh dermatology group had growing patient volume across SRT, biopsies, cosmetics, and excision procedures — but patient collections had plateaued at ~$50K/month. Front desk staff had no standardized workflow, no tool to quote patient responsibility, and no outbound follow-up process.

Master Billing deployed a three-pillar system: a custom Patient Responsibility Calculator, full-day on-site staff training with scripted workflows, and a systematic weekly outbound calling program. Within six months, the practice hit a record $81K month — 60%+ above baseline — and captured $204K+ in incremental revenue.
