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 software is a feature that some encoders have. 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, which include less time spent coding and more accurate coding.

Despite these advantages, there are also a few disadvantages of computer assisted coding. First, the type of EHR system a healthcare organization utilizes may impact coding accuracy. Computer assisted coding has also been less successful with larger records. Last, computer assisted coding technology needs to be updated when codes are added.
