ICD-10 Updates for 2019
Effective October 1, 2018

For the latest diagnosis codes and guidelines go to the CMS (Centers for Medicare and Medicaid Services) website. Once on the CMS ICD-10 (The International Classification of Diseases 10th Edition) website you can download the 2019 ICD-10 diagnosis code set that goes into effect on October 1, 2018. Since 2016 when ICD-10 became the official code set for the United States we saw several changes to cardiovascular diagnosis codes. No more hypertension table, we now have a new way to code hypertension (I10 - I15). We have new diagnosis codes for STEMI/NSTEMI (I21 – I22.9), saw a change with the heart failure diagnosis codes (I50 – I50.9) and new for 2018 were the myocardial infarction codes (I21.4 - I21.A9) broken down by types. With these specific codes we encourage providers, staff, and coders to help everyone code as specifically as possible. Accurate documentation allows a better understanding of the care for the patient and allows a better avenue for the collection of data.

CMS has also released the 2019 coding guidelines for ICD-10. It is a good idea to review the guidelines each year to see if any changes were made.
