Other specified mononeuropathies of right upper limb

This code signifies a mononeuropathy affecting a specific nerve in the right upper limb, other than those with dedicated ICD-10-CM codes (e.g., carpal tunnel syndrome, ulnar nerve entrapment). It indicates nerve dysfunction in the right arm, forearm, or hand due to a localized injury, compression, or other identifiable cause.

Use this code when documentation specifies a mononeuropathy of the right upper limb that doesn't fit a more specific code. Examples include radial nerve palsy not due to fracture, anterior interosseous nerve syndrome, or suprascapular nerve entrapment affecting the right side. Documentation should clearly identify the affected nerve and the laterality.

• Ensure the documentation specifies "right upper limb" to support laterality.
• Always search for a more specific code first (e.g., G56.01 for carpal tunnel syndrome, right wrist).
• This code requires a definitive diagnosis of mononeuropathy, not just symptoms like numbness or tingling.
