Now is the Time to Get Ready for 2021 ICD-10-CM Updates

October 1, 2020, will soon be upon us – and bring with it the 2021 ICD-10-CM coding updates. There will be more than 550 coding changes including 490 code additions, 47 revisions and 58 deleted codes. Some specialties will need to closely monitor the list because of the volume of proposed revisions and additions that apply to them, including general practitioners, ophthalmology, hematology, and rheumatology.

Many additions in ophthalmology involve laterality or location definitions. Hematology will see the revision and addition of new codes for sickle-cell anemia, while rheumatology has several new codes for arthritis.

Over 50 new codes will be devoted to diagnoses involving the thorax, such as abrasions and superficial injuries. Fentanyl and tramadol poisonings account for 18 new codes each. And, if your patient is hit by or injured on an electric scooter or a ‘standing micro-mobility pedestrian conveyance,’ there will be over 100 new codes to choose from to describe the accident.

Coding changes can be overwhelming for even the most experienced health care professional. To make things easier, we’ve compiled a quick list of some of the more general codes slated to begin on October 1.

Next steps:

We suggest the following next steps to ensure your organization is ready for the changes ahead:

  1. Watch for the final ruling on the proposed changes that will be posted on the CMS website.
  2. Review and update any templates providers use to help them document or determine diagnosis.
  3. Ensure that your software systems are ready: confirm new codes will be used and old codes inactivated for dates of service from October 1, 2020, onwards.
  4. Perhaps most importantly, take the time to educate providers about the new codes so they can code correctly from the beginning.
