ICD-10 Code G56.41 – Causalgia of right upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G56.41 – Causalgia of right upper limb
What it is
G56.41 identifies causalgia affecting the right upper limb. Use it for severe, burning neuropathic pain in the right arm or hand when documentation specifies causalgia.
Clinical signs
Typical findings include persistent burning pain, marked sensitivity to touch, and pain out of proportion to the injury. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents causalgia in the right upper extremity, including the arm, forearm, wrist, or hand. It may appear after nerve injury or other neuropathic pain conditions, but you should code only when the right-sided location is clearly stated.
Do not use for
Do not use it for unspecified limb pain, left-sided symptoms, or general neuropathy without causalgia. Check documentation if the record does not clearly identify the right upper limb.
Coding tip
Verify laterality and the exact term “causalgia” before assigning G56.41.
