Complex regional pain syndrome I of lower limb, bilateral
ICD-10 G90.523 is a billable code used to indicate a diagnosis of complex regional pain syndrome i of lower limb, bilateral.
Complex Regional Pain Syndrome (CRPS) I, previously known as Reflex Sympathetic Dystrophy (RSD), is a chronic pain condition that typically affects a limb after an injury or surgery. In the case of G90.523, the syndrome manifests bilaterally in the lower limbs. Patients often experience severe, persistent pain that is disproportionate to the initial injury. Symptoms may include swelling, changes in skin color and temperature, and abnormal sweating. The pain is often described as burning or throbbing and can be accompanied by motor dysfunction, such as weakness or tremors. The exact pathophysiology of CRPS is not fully understood, but it is believed to involve a combination of peripheral and central nervous system changes, including dysregulation of the autonomic nervous system. Diagnosis is primarily clinical, based on patient history and symptomatology, and may be supported by imaging studies or nerve conduction tests. Treatment typically involves a multidisciplinary approach, including pain management, physical therapy, and psychological support.
Detailed pain assessments, treatment plans, and response to therapies.
Patients presenting with chronic pain following surgery or trauma.
Documentation must clearly outline the bilateral nature of the condition and any functional limitations.
Neurological evaluations, imaging studies, and assessments of autonomic function.
Patients with neurological symptoms following an injury, requiring differential diagnosis.
Neurological assessments should include detailed descriptions of sensory and motor deficits.
Used for initial assessment of CRPS symptoms and functional limitations.
Detailed evaluation of pain, range of motion, and functional status.
Physical therapists should document specific interventions and patient responses.
CRPS I occurs without confirmed nerve injury, while CRPS II is associated with a specific nerve injury. Both conditions present with similar symptoms, but the underlying causes differ.
