Increasing revenue and recovery

Wipfli had the right combination of medical, compliance and financial knowledge and experience to audit the billing and collections processes at Waukesha County’s Department of Health and Human Services.

The Challenge

In Waukesha County, Wisconsin, the Department of Health and Human Services (DHHS) was due for an internal, risk-based audit to help ensure compliance with a wide range of rules and regulations and complicated billing and collections processes. Wipfli assembled a cross-functional team with expertise in medical billing, medical information systems and internal audits. Using a risk-based approach, Wipfli audited billable services that brought in the greatest share of revenue.

The Solution

Wipfli’s team conducted process walk-throughs and detailed transaction testing to evaluate:

  • Effectiveness of internal controls over billing.
  • Accuracy of medical coding.
  • Adherence to processes.
  • Timeliness of transactions.
  • Use of the practice management system.
  • Soundness of DHHS’s IT infrastructure.
Wipfli staff was pleasant and professional with all staff involved in this audit. They provided valuable insights throughout the audit process. Recommendations were well thought out and will assist us in improving our operations.

The results

The general control structure of the DHHS IT system was sound, but Wipfli identified areas where the practice management system could be utilized better. Wipfli’s final report offered DHHS several opportunities to improve processes, accuracy and compliance and apply best practices in billing and accounts receivable. By adopting these suggestions, DHHS expects to increase revenue and recovery — which will help the county provide vital services to individuals and families.
