Complex regional pain syndrome I of right lower limb
ICD-10 G90.521 is a billable code used to indicate a diagnosis of complex regional pain syndrome i of right lower limb.
Complex Regional Pain Syndrome (CRPS) I, previously known as Reflex Sympathetic Dystrophy (RSD), is a chronic pain condition that typically affects a limb following an injury or surgery. In the case of G90.521, the syndrome specifically affects the right lower limb. Patients often experience severe, persistent pain that is disproportionate to the initial injury, along with other symptoms such as swelling, changes in skin color and temperature, and abnormal sweating. The pain is believed to arise from a malfunction in the peripheral and central nervous systems, leading to an exaggerated response to pain signals. Autonomic dysfunction is also a hallmark of CRPS, contributing to the symptoms of altered blood flow and temperature regulation in the affected limb. Diagnosis is primarily clinical, based on the history of pain and associated symptoms, and may involve imaging studies to rule out other conditions. Treatment often includes pain management strategies, physical therapy, and in some cases, nerve blocks or medications aimed at modulating nerve activity. Early diagnosis and intervention are crucial to improve outcomes and reduce the risk of long-term disability.
Detailed records of pain assessments, treatment plans, and patient responses to therapies.
Patients presenting with chronic pain following an injury, requiring multidisciplinary management.
Documentation must clearly outline the progression of symptoms and the impact on daily functioning.
Comprehensive neurological evaluations, including sensory and motor assessments.
Patients with neuropathic pain and autonomic dysfunction requiring diagnostic clarification.
Neurological assessments should be well-documented to support the diagnosis of CRPS.
Used for pain management in patients with CRPS I.
Document the indication for the nerve block and patient response.
Pain management specialists should ensure comprehensive pain assessments are included.
CRPS I typically develops after an injury or surgery, but the exact cause is not fully understood. It is believed to involve a combination of nerve injury, inflammation, and abnormal pain processing.
