Hello!

Every year the ICD 10 diagnosis book releases its annual updates. This year there are 71932 codes with 279 additions, 51 deletions and 143 revised codes.

Of all the changes, one of the most common codes that is changing is MYALGIA.

Please note that M79.1 will no longer be a valid code on 10/1/18! Instead, it will require a 5th digit extender.

M7910 Myalgia, unspecified site

M7911 Myalgia of mastication muscle

M7912 Myalgia of auxiliary muscles, head and neck

M7918 Myalgia, other site

If you have any questions or would like to inquire on any of the other code changes, send me an email!

Thanks!
