Notes for Primary Care – ICD-10-CM 2018: Changes to Tabular List Instructions (not all inclusive)
The following tables compare the ICD-10-CM tabular list entries for 2017 and 2018 for those conditions that may be frequently
diagnosed and/or managed in primary care. Code numbers in bold font are complete codes. All others require additional characters for
completion. New tabular list instructions are underlined. Please see the index and full tabular list in your coding manual or other coding
reference for code selection. (Please do check for errors. A lot of cut and paste functionality was used in creating this document based
on the 67-page addenda for the 2018 ICD-10-CM tabular list. Chances are some errors were introduced.)
