Summary of 2019 ICD-10 Coding Updates for DentalWriter Users

In total, there were: 279 additions, 51 deletions, 143 revisions

Link to full list of changes: ftp://ftp.cdc.gov/pub/Health_Statistics/NCHS/Publications/ICD10CM/2019/icd10cm_codes_addenda_2019.txt

These changes go into effect October 1, 2018.

Many of the codes that were added/deleted/revised were in relation to eyes, hands, and pregnancy. However, a few major changes that may effect dental practices who bill medical insurance for medically necessary procedures performed in the dental  practice: (don't worry, we'll have these all ready to go for you in DentalWriter!)

Funny thing – M26.621 (Arthralgia Right TMJ) does actually show up as a revised code. However, the only revision a spacing error was corrected (removed 1 space) in between the word “temporomandibular” and “joint” :)
