Complex regional pain syndrome I of unspecified lower limb
ICD-10 G90.529 is a billable code used to indicate a diagnosis of complex regional pain syndrome i of unspecified 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 trauma. In the case of G90.529, the unspecified lower limb indicates that the specific limb affected is not documented. CRPS is characterized by severe, persistent pain that is disproportionate to the initial injury, often accompanied by changes in skin color, temperature, and swelling. The pain may be described as burning, throbbing, or aching and can be exacerbated by touch or movement. Autonomic dysfunction is a hallmark of CRPS, leading to symptoms such as sweating abnormalities and changes in hair and nail growth. The pathophysiology of CRPS involves a complex interplay of peripheral and central nervous system mechanisms, including neurogenic inflammation and altered pain processing. Diagnosis is primarily clinical, based on patient history and symptomatology, and may be supported by imaging studies or nerve conduction tests. Early recognition and intervention are crucial to improve outcomes and prevent progression to chronic pain states.
Detailed pain assessments, treatment plans, and response to therapies.
Patients presenting with chronic pain following trauma, requiring multidisciplinary management.
Documentation must clearly outline the relationship between the injury and the onset of CRPS symptoms.
Neurological evaluations, imaging studies, and differential diagnoses.
Patients with neurological symptoms following limb injury, requiring diagnostic clarification.
Neurological assessments should include autonomic function tests if indicated.
Used for initial assessment of CRPS symptoms and development of a treatment plan.
Detailed evaluation of pain, function, and treatment goals.
Physical therapists should document the impact of CRPS on daily activities.
CRPS I occurs without identifiable nerve injury, while CRPS II is associated with a specific nerve injury. Both conditions present with similar symptoms but differ in their underlying causes.
