What has happened to this code
Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
- FY2012 Added to the draft code set draft Carpal tunnel syndrome
Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from G56 Mononeuropathies of upper limb
Excludes1 - never coded here
- current traumatic nerve disorder - see nerve injury by body region
Inherited from the G50-G59 section Nerve, nerve root and plexus disorders (G50-G59)
Excludes1 - never coded here
- current traumatic nerve, nerve root and plexus disorders - see Injury, nerve by body region
- neuralgia NOS (M79.2)
- neuritis NOS (M79.2)
- peripheral neuritis in pregnancy (O26.82-)
- radiculitis NOS (M54.1-)
How CDC's index refers to this code
Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
