Causalgia of upper limb
ICD-10 G56.4 is a billable code used to indicate a diagnosis of causalgia of upper limb.
Causalgia of the upper limb, classified under G56.4, is a complex pain syndrome characterized by severe burning pain, typically following a nerve injury. This condition often arises after trauma or surgery affecting the peripheral nerves, particularly in the upper extremities. Patients may experience allodynia, hyperalgesia, and changes in skin temperature and color. The pain is often disproportionate to the initial injury and can be accompanied by sensory and motor deficits. Causalgia is part of the broader category of complex regional pain syndrome (CRPS), which includes both CRPS I (reflex sympathetic dystrophy) and CRPS II (causalgia). Diagnosis is primarily clinical, supported by patient history and physical examination, and may involve nerve conduction studies to assess the integrity of the affected nerves. Treatment options include pharmacotherapy, physical therapy, and in some cases, surgical interventions. Understanding the nuances of causalgia is essential for accurate coding and appropriate management of affected patients.
Detailed neurological examination findings, including sensory and motor assessments.
Patients presenting with chronic pain following upper limb trauma or surgery.
Neurologists should document the specific nerve involved and any diagnostic tests performed.
Comprehensive pain assessments, treatment plans, and response to therapies.
Management of patients with chronic pain syndromes, including causalgia.
Pain specialists should document the impact of pain on daily activities and quality of life.
Used to evaluate nerve function in patients with suspected causalgia.
Document the specific nerves tested and the rationale for the study.
Neurologists should correlate findings with clinical symptoms.
Causalgia is primarily caused by nerve injury, often following trauma or surgical procedures, leading to abnormal pain signaling.
Diagnosis is based on clinical evaluation, patient history, and may include nerve conduction studies to assess nerve function.
