Although the official start of summer is not until tomorrow at 5:07 AM Central Time, here in Alabama the oppressive humidity and heat activated thunderstorms have already begun. Additionally, and much to my delight, I am already seeing more lightening bugs in the night sky than in recent years. This brings to mind the oft made statement by Mark Twain, “the difference between the almost right word and the right word is really a large matter. ‘tis the difference between the lightening bug and the lightening.”

The same analogy can be made for documentation in a medical record. CMS posted the FY 2019 ICD-10-CM diagnosis code updates to the CMS website on June 11, 2018. Several of the updates revise or expand a code description. Professional Coders and Clinical Documentation Improvement Specialists should take on the challenge of a little summer reading to find out what is changing. In the meantime, here are a few highlights about what will change come October 1, 2018.

Code Changes by the Numbers:

The FY 2019 ICD-10-CM codes updates includes:

  • 279 New Codes
  • 143 Revised Titles
  • 51 Deleted Codes
  • 71,932 Total Codes for FY 2019. (Increase from 71,704 in FY 2018).

(*)Note, code Z62813 falls within the Z62 category “Problems Related to Upbringing.” This is one of the ICD-10-CM code categories that identifies patients with potential health hazards related to socioeconomic and psychosocial circumstances. Coding Clinic for ICD-10-CM/PCS, First Quarter 2018 advised that it would be acceptable to report these codes based on documentation from non-physician clinicians following the patient. You can read more about the Z55-Z65 code categories in a related MMP article about Social Determinants of Health.

Information about the FY 2019 ICD-10-CM code updates can also be found on the Centered for Disease Control and Prevention (CDC) website at: Reminder, the code updates will be used for discharges occurring from October 1, 2018 through September 30, 2019.
