Some ICD-10-CM Codes Expanded for 2019

Some ICD-10-CM Codes Expanded for 2019

If you are a particularly observant medical coder, you’ve probably noticed that many codes identified as deleted were actually promoted to new roles. Nearly 50 codes were revamped to become parent codes of more specific codes,and it’s causing some confusion because some electronic coding systems mark them as deleted AND new.

Same Codes Marked as Deleted/New

Take C43.11  Malignant melanoma of right upper eyelid, including canthus, for example. Marked “no change” in the 2019 ICD-10-CM Addendum by CMS, the code received two new codes indented underneath for added specificity.

C43.111 Malignant melanoma of right upper eyelid, including canthus

C43.112 Malignant melanoma of right lower eyelid, including canthus

The next code, C43.12 Malignant melanoma of left upper eyelid, including canthus also received new codes. However, depending on the your encoder, it will show the code as both deleted and new.

Other codes are receiving this treatment, and it’s a good idea to keep your wits about you as you identify them in reports. Be sure to report the inconsistency to your coworkers and supervisors, along with your look-up program, encoder, and EMR provider.
