Nerve root and plexus compressions in diseases classd elswhr

This code describes the compression of a nerve root or nerve plexus that is a manifestation of an underlying disease process classified elsewhere in the ICD-10-CM system. It signifies neurological symptoms directly attributable to this compression, such as pain, weakness, or sensory changes, stemming from a systemic or non-spinal condition.

Use this code when documentation clearly links nerve root or plexus compression to a primary disease process that is not inherently a spinal disorder. Examples include nerve compression secondary to diabetes mellitus (diabetic polyneuropathy with radiculopathy), neoplastic disease (tumor compressing a nerve root), or infectious processes. The underlying disease must be coded first.

• Always sequence the underlying disease responsible for the nerve compression first, followed by this code.
• Carefully review documentation to ensure the nerve compression is due to a disease classified elsewhere, and not a primary spinal condition.
• Pay close attention to the "Excludes1" notes; these conditions are never coded with G55. If the compression is due to one of the excluded conditions, use the specific code for that condition.
