2019 ICD-10 Codes for Chiropractors.

Yes, the 2019 ICD-10 Codes for Chiropractors Start NOW

We’ve been receiving a number of emails from confused docs and their billing staff who are asking if the 2019 ICD-10 codes for chiropractors begin now (in October 2018) or later (in January 2019).

The short answer is: even though the newest code set is named ICD-10 2019, the codes go into effect starting October 1, 2018!

What 2019 ICD-10 Codes for Chiropractors Will Change? 

Fortunately, the list of code changes that are in effect as of October 2018 is shorter than in previous years, but there are a few significant alterations to the codes.


The one code change that will likely impact the most chiropractors is the Myalgia series.  Prior to the change, M79.1 covered any type of Myalgia, located anywhere.

In the 2019 ICD-Codes for Chiropractors, you will want to note that there is some more specificity for this code, as outlined below:

  • M79.10 — Myalgia, unspecified site
  • M79.11 — Myalgia of mastication muscle
  • M79.12 — Myalgia of auxiliary muscles, head and neck
  • M79.18 — Myalgia, other site

As usual, it is always best to be as specific as possible when choosing the appropriate diagnosis code.  That means while the “unspecified” code is an option, it may not be the best option because it’s essentially opening yourself up for a payer question: where is the patients myalgia?

Also, it is important to remember that there are other 2019 ICD-10 Codes For Chiropractors that exist and that may more accurately describe other conditions similar to Myalgia.  For example, Fibromyalgia is still a valid code at M79.7; similarly, the Myositis series (M60.0-M60.9) are separate and distinct from Myalgia.  So, using either of these other codes is both still an option AND they should not be used in conjunction with Myalgia.

Muscular Dystrophy

Similar to Myalgia, the previous codeset for Muscular Dystrophy had one generic option (G71.0).  The new 2019 codeset will include a few additional choices to cover specific types of MD, as listed below:

  • M71.00 — Muscular Dystrophy, unspecified 
  • M71.01 — Duchenne or Becker Muscular Dystrophy
  • M71.02 — Facioscapulohumeral Muscular Dystrophy
  • M71.09 — Other specified Muscular Dystrophies

Fortunately, as I stated above, most of us will have few changes to make in terms of 2019 ICD-10 Codes for Chiropractors.

Most importantly, take note of the addition and deletions above, and put them into place starting October 1, 2018!
