Nerve root and plexus compressions in diseases classified elsewhere (G55) ICD-10-CM
The G55 code range covers nerve root and plexus compressions in diseases classified elsewhere with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
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.
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 G55 Code Range
The ICD-10 code G55 is used for documenting nerve root and plexus compressions related to other diseases. This code specifically applies when nerve compression occurs as a complication of conditions classified in other ICD-10 categories.
G55G55 would be the appropriate ICD-10 code to reflect that complication. Recognizing the specific use of this code ensures proper classification and aids in treatment planning and medical record accuracy for conditions involving nerve compression linked to systemic or neoplastic diseases.
