HIPAA-Compliant Patient Revenue Predictive Model

Develop an advanced Excel forecasting model using Power Query and Monte Carlo simulation to predict patient revenue while maintaining strict HIPAA data anonymization. The model must incorporate historical billing data, treatment complexity factors, insurance reimbursement rates, and probabilistic risk assessment. Include VBA macro functionality to automatically scrub personal identifiers and generate encrypted summary reports. Ensure all calculations can handle multiple data sources without compromising patient privacy.
