Foot drop, left foot
ICD-10 M21.372 is a billable code used to indicate a diagnosis of foot drop, left foot.
Foot drop, also known as drop foot, is a condition characterized by difficulty in lifting the front part of the foot, leading to a dragging of the foot while walking. This condition can be unilateral, as in the case of M21.372, which specifies foot drop of the left foot. Acquired foot drop is often due to neurological conditions, such as peroneal nerve injury, stroke, multiple sclerosis, or muscular dystrophy. It may also arise from orthopedic issues, such as a fracture or surgery affecting the ankle or knee. Patients with foot drop may exhibit a steppage gait, where they lift their knee higher than normal to avoid dragging the foot. This can lead to secondary complications, including falls and injuries. Treatment options may include physical therapy, ankle-foot orthoses (AFOs), and in some cases, surgical interventions to correct the underlying cause. Understanding the etiology of foot drop is crucial for effective management and rehabilitation.
Detailed neurological examination findings, including motor function tests and nerve conduction studies.
Patients presenting with unilateral weakness, history of stroke, or peripheral neuropathy.
Ensure documentation reflects the neurological assessment and any imaging studies performed.
Surgical reports, imaging studies, and physical examination findings related to the lower extremity.
Post-operative patients with foot drop following knee or ankle surgery.
Document any orthopedic interventions and their outcomes to support coding.
Used when a patient requires an AFO due to foot drop.
Document the need for the orthosis and the patient's functional limitations.
Orthopedic specialists should provide detailed notes on the fitting and adjustments of the orthosis.
Foot drop is primarily caused by weakness or paralysis of the muscles that lift the foot, often due to peroneal nerve injury, neurological disorders, or orthopedic issues.
