Important Updates to ICD-10

It’s that time of year again. As you may be aware, every year since its inception, there have been updates to ICD-10 codes. Some years have more changes, others fewer. As of October 1, 2018 the following changes will go into effect:

M79.1 myalgia will be deleted and replaced with the following codes:

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

Type 1 excludes include M79.7-fibromyalgia and M60.9 myositis.  If you are diagnosing myalgia in a region other than muscles of mastication or head/neck it is advised to use M79.18 as M79.10 is a non-specific code.

  • G71.00 muscular dystrophy, unspecified
