(Valid) Effective Date: N/A Diseases of the nervous system - Mononeuropathies of lower limb 6 Feed
Causalgia of lower limb. This condition is characterized by prolonged, severe pain, changes in skin color or temperature, and swelling in the affected area.
Medical necessity must be established by demonstrating that the reported symptoms are consistent with causalgia and result in significant functional impairment.The documentation should support the need for the chosen treatment modalities.
Diagnosis of causalgia is based on a patient’s medical history, physical examination, and reported symptoms. Imaging studies like MRI or bone scans may be used to rule out other conditions. Treatment may involve physical therapy, medication (NSAIDs, antidepressants, anticonvulsants, corticosteroids), biofeedback, sympathetic nerve blocks, spinal cord stimulation, and in severe cases, sympathectomy or intrathecal drug delivery.
In simple words: Causalgia of the lower limb is a painful condition that can occur after a nerve injury in your leg or foot.The pain can be severe and burning, and the skin in the affected area may change color or temperature. You might also experience swelling, sweating, and muscle weakness in the area.
Causalgia of the lower limb, also known as complex regional pain syndrome II (CRPS II), is a chronic pain condition that develops after a nerve injury in the thigh, lower leg, or foot.It is characterized by burning or throbbing pain, changes in skin color, temperature, and texture, swelling, sweating, muscle spasms, tremors, weakness, and potential changes in nail and hair growth.The pain is often severe and disproportionate to the initial injury, and may be accompanied by allodynia (pain from normally non-painful stimuli) and hyperalgesia (increased sensitivity to pain).Movement of the affected limb may be limited.
Example 1: A patient experiences persistent burning pain and swelling in their left foot several weeks after a fracture. The skin is cool to the touch and discolored.Diagnosis: Causalgia of lower limb., Following a minor cut on their lower leg, a patient develops intense pain, allodynia, and skin changes.The pain is much worse than expected from the initial injury.Diagnosis: Causalgia of lower limb., A patient reports constant throbbing pain, excessive sweating, and muscle weakness in their lower leg after a surgical procedure.The pain is out of proportion to the expected post-operative discomfort.Diagnosis: Causalgia of lower limb.
Documentation should include details of the initial injury, location and nature of the pain (burning, throbbing, etc.), associated symptoms (swelling, skin changes, allodynia, hyperalgesia, etc.), and functional limitations. Diagnostic workup (e.g., imaging studies) if performed should also be documented.
