Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the G50–G59 Code Range
These conditions affect nerves, nerve roots, and plexuses, which are networks of nerves. The categories separate cranial nerve disorders, nerve root and plexus disorders, and problems affecting individual nerves in the limbs or elsewhere.
G50 and G51 name the trigeminal and facial nerves. G52 separates other cranial nerve disorders by nerve, including disorders of multiple cranial nerves. G54 distinguishes nerve roots from plexuses and identifies body regions; it also includes phantom limb syndrome with or without pain.
G56 and G57 separate upper-limb from lower-limb nerve disorders, then distinguish specific nerves and conditions. G58 holds other disorders of individual nerves. G53, G55, and G59 identify nerve disorders or compressions associated with diseases classified elsewhere.
Questions About This Page
How many codes are in the G50-G59 range?
The G50-G59 range contains 131 ICD-10-CM diagnosis codes in FY 2027. 106 of them are billable, and the rest are category headers that organize the section.
What conditions does G50-G59 cover?
The range covers nerve, nerve root and plexus disorders. The code ranges listed above break it into groups of related conditions, and each one links to its own page with the full code list.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
