How is G90.51 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to G90.51. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Syndrome › pain › complex regional I › upper limb
Excludes1 — never code together — inherited from G90
The conditions below can never be reported together with G90.51 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- dysfunction of the autonomic nervous system due to alcohol (G31.2)
Excludes1 — never code together — inherited from G90.5
The conditions below can never be reported together with G90.51 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
