Question: When I was looking through the list of new ICD-10 2018 codes, I noticed additional options for diabetes. As a podiatry coder, how important is it for me to learn these new codes? Minnesota Subscriber Answer: Effective on Oct. 1, 2017, your new type 2 diabetes mellitus coding choices are as follows: More than 29 million people in America have diabetes, according to a 2016 CDC report. An estimated 86 million have pre-diabetes, which increases a patient's risk of type 2 diabetes and other chronic conditions. Diabetes damages blood vessels and nerves, especially patients' feet, according to the report. This damage can lead to serious, hard-to-treat infections where amputation is sometimes necessary to stop the infection from spreading. As a podiatry coder, the severity of this epidemic makes it vital to understand for you to understand how to code for diabetes.
