The Growing Benefits of Computer Aided Coding Technology

Computer Aided Coding (CAC) has come a long way in a short time. What started as a way to help clinical coders manage the ever-increasing complexity of their workloads has now evolved into a technology solution that delivers benefits to entire organizations.

Drivers of the transition to the CAC

The shift from paper-based data entry to electronic data entry offers the opportunity to use new technologies, including artificial intelligence, to automate not only the assignment of codes, but also the many separate and disparate coding processes. and CDI workflow in general.

Additionally, with the growing adoption of EMRs, hospitals in the Asia-Pacific region are now looking for CAC solutions that leverage their existing platforms to improve productivity.

Now, with ICD-11 on the horizon and the growing need for data interoperability, there is a growing opinion among HIMs and clinical coding teams that coding automation is not only inevitable but also welcome.

Benefits across the organization

Adopting CAC has now been shown to have positive effects that go beyond improving coding accuracy and productivity.

To understand the impacts of the technology, 3M commissioned a survey of US hospitals and healthcare systems. The objective of the survey was to understand the benefits of CAC technology for the health information management and revenue cycle managers of these organizations.

The survey showed that CAC technology improves productivity and key quality metrics, reduces the need for outsourcing and rework requests, and drives financial success.


Sixty-eight percent of survey respondents indicated that CAC solutions improve productivity. And the more an organization uses and becomes familiar with CAC, the more pronounced the impact becomes. Among those who have used CCAs for five years or more, 88% reported an increase in productivity.


CAC solutions have also been found to have a significant impact on capture quality and complexity. Superior CDI and coding capabilities result in cleaner codes the first time, allowing organizations to focus more on quality metrics and improve accuracy and reliability. In the US survey, 65% of respondents said that CACs help improve quality measures.

Outsourcing, takeover and DNFB

The survey revealed that the need for outsourcing is significantly reduced when hospitals implement CAC technology. Those who had been using CAC for more than five years noted a 74% reduction in outsourcing. The survey also showed significant reductions in rework claims and unbilled time off (DNFB).

Financial success

Survey participants generally agree that CVC will contribute to future financial success. Ninety-two percent of organizations using CAC solutions for five years or more agreed or strongly agreed that CAC will drive financial success in the future.

Reason to be confident

The US experience shows that implementing CAC technology solutions not only improves coding productivity and accuracy, but also quality metrics and hospital reimbursement. Continued use of technology enhances these benefits and ensures that organizations are prepared for any future changes to coding guidelines.

Although CAC technology is still in its infancy in the Asia-Pacific region, there is good reason to be confident that hospitals will see a significant return on investment for many years to come.
