CACS stands for computer assisted coding system. It is software that analyzes healthcare documents and produces medical codes for specific phrases. The software can be thought of as “spell check” in order to highlight key terms in a document. For example, say in a document a doctor is diagnosing a patient having cancer. CACS will determine the term “cancer” needs coding, but not for someone who wrote cancer in their family history.
Before coding was performed by coders, however, the shift of a more technology savvy healthcare system has increased the demand for medical coding systems, like CACS. CACS is mostly used for routine procedures and leaves the coders for more complex situations.

CACS is applied to health informatics because it is an easier and faster way to code through documents. Before it was up to the coder to get everything done without a mistake. Now, CACS does the routine procedure and gives the coders more time to deal with complex situations. CACS minimizing time of coding will result in millions of dollars being saved.
