Wrist drop, right wrist
ICD-10 M21.331 is a billable code used to indicate a diagnosis of wrist drop, right wrist.
Wrist drop, also known as radial nerve palsy, is a condition characterized by the inability to extend the wrist and fingers, resulting in a characteristic drooping of the wrist. This condition typically arises from an acquired deformity due to nerve injury, often resulting from trauma, compression, or prolonged pressure on the radial nerve. Patients may present with weakness in wrist extension, leading to difficulties in grasping objects and performing daily activities. The right wrist is specifically affected in this code, indicating a unilateral presentation. The underlying pathophysiology involves damage to the radial nerve, which innervates the extensor muscles of the forearm. Treatment may include physical therapy, splinting, and in some cases, surgical intervention to relieve nerve compression or repair nerve damage. Accurate coding is essential for proper reimbursement and to reflect the severity and impact of the condition on the patient's functional abilities.
Detailed history of injury, physical examination findings, and treatment plan.
Post-traumatic wrist drop following humeral shaft fractures or compression injuries.
Documentation should clearly outline the mechanism of injury and any associated fractures.
Neurological examination findings, imaging studies, and response to treatment.
Radial nerve palsy due to compression from tumors or systemic diseases.
Ensure to document any underlying neurological conditions that may contribute to the presentation.
Used when surgical intervention is required for nerve repair.
Operative report detailing the procedure and indication for surgery.
Orthopedic or neurosurgical documentation should include pre-operative assessments.
Wrist drop is primarily caused by injury to the radial nerve, which can occur due to trauma, compression, or prolonged pressure.
Diagnosis is made through clinical examination, patient history, and may be supported by imaging studies to assess nerve integrity.
Treatment options include physical therapy, splinting, and surgical intervention if there is significant nerve damage or compression.
