Wrist drop, unspecified wrist
ICD-10 M21.339 is a billable code used to indicate a diagnosis of wrist drop, unspecified wrist.
Wrist drop, also known as radial nerve palsy, is characterized by the inability to extend the wrist and fingers, resulting in a characteristic 'wrist drop' posture. This condition can arise from various causes, including trauma, compression, or systemic diseases affecting the radial nerve. The clinical presentation typically includes weakness in wrist and finger extension, leading to difficulties in grasping objects and performing fine motor tasks. Patients may also experience numbness or tingling in the back of the hand and forearm. The condition can be classified as either congenital or acquired, with acquired forms being more common. Acquired wrist drop often results from external compression, such as prolonged pressure on the radial nerve, or from injuries such as humeral shaft fractures. Treatment may involve physical therapy, splinting, and in some cases, surgical intervention to relieve nerve compression or repair nerve damage. Accurate diagnosis and coding are essential for appropriate management and reimbursement.
Detailed history of injury, physical examination findings, and imaging results.
Patients presenting with wrist drop following trauma or surgery.
Documentation should clearly outline the mechanism of injury and any associated fractures.
Neurological examination findings, including sensory and motor assessments.
Patients with wrist drop due to systemic diseases or neurological conditions.
Documentation must include a thorough review of neurological history and differential diagnoses.
Used in cases where surgical intervention is required to relieve compression.
Operative report detailing the procedure and indication.
Orthopedic surgeons should document the rationale for surgery.
Wrist drop is primarily caused by radial nerve injury, which can occur due to trauma, compression, or systemic diseases.
Diagnosis is made through clinical examination, assessing the ability to extend the wrist and fingers, and may be confirmed with electromyography.
Treatment options include physical therapy, splinting, and in some cases, surgical intervention to relieve nerve compression.
