What is an encoder in medical coding?
An encoder is a piece of software that uses a set of terminology to select medical codes. The terminology branches from general to more specific codes to help providers accurately record the right code. Medical professionals leverage the ICD-10-CM together with encoders to help classify disease.
What is computer assisted coding (CAC)?
Computer assisted coding (CAC) software is a feature offered by certain encoders. CAC systems utilize natural language processing (NLP) to suggest CPT and ICD codes that may be associated with certain diagnoses.
Computer assisted coding pros and cons
There are several benefits of computer assisted coding, namely less time spent coding and more accurate coding.
Despite these advantages, there are also a few disadvantages of computer assisted coding. First, certain types of EHR systems may not be fully compatible with CAC software, impacting coding accuracy. CAC software can also struggle to process large records, especially if duplicate or incomplete entries are included. When codes are added to the ICD-10-CM, CAC software must be appropriately updated as well.
