Wrist drop (acquired)
ICD-10 M21.33 is a billable code used to indicate a diagnosis of wrist drop (acquired).
Wrist drop, also known as radial nerve palsy, is a condition characterized by the inability to extend the wrist and fingers due to weakness or paralysis of the extensor muscles. This acquired deformity typically results from trauma, compression, or injury to the radial nerve, which can occur from various causes such as fractures of the humerus, prolonged pressure on the nerve (e.g., from crutches), or systemic diseases like diabetes. Patients with wrist drop may present with a characteristic 'wrist drop' posture, where the wrist is flexed and the fingers are unable to extend, leading to functional impairment in hand use. The condition can significantly affect daily activities, including grasping objects and performing fine motor tasks. Treatment often involves physical therapy, splinting, and in some cases, surgical intervention to relieve nerve compression or repair nerve damage. Understanding the underlying cause of the wrist drop is crucial for effective management and rehabilitation.
Detailed notes on the mechanism of injury, physical examination findings, and treatment plans.
Patients presenting with wrist drop following humeral fractures or after prolonged pressure on the radial nerve.
Ensure to document any surgical interventions or physical therapy referrals.
Comprehensive neurological assessments, including motor function tests and nerve conduction studies.
Patients with wrist drop due to systemic conditions like diabetes or multiple sclerosis.
Document any neurological evaluations and the patient's response to treatment.
Used when surgical intervention is required for nerve repair.
Surgical notes detailing the procedure and indications.
Orthopedic or neurosurgical documentation should clearly outline the rationale for surgery.
Wrist drop is primarily caused by injury or compression of the radial nerve, which can occur due to trauma, prolonged pressure, or systemic diseases.
