Select the ICD-10-CM code for lesions of the brachial plexus.

• A. G54.2
• B. G54.1
• C. G45.0
• D. G54.0

Answer: (D)

In ICD-10-CM, disorders of the brachial plexus are grouped under the G54 block, which covers various brachial plexus conditions. When the documentation refers to a lesion of the brachial plexus without specifying a more exact type (like neuritis or a particular brachial plexus syndrome), the general code for brachial plexus disorders is used. That makes the broad code the best fit for “lesions of the brachial plexus.” The other codes imply different, more specific conditions: neuritis, other specified brachial plexus disorders, or a brain vascular event, which would not be appropriate for a peripheral nerve lesion of the brachial plexus.
