Foot drop (acquired)
ICD-10 M21.37 is a billable code used to indicate a diagnosis of foot drop (acquired).
Foot drop, also known as drop foot, is a condition characterized by difficulty in lifting the front part of the foot, leading to dragging of the foot while walking. This acquired deformity can result from various underlying causes, including neurological disorders, muscular diseases, or injuries affecting the peroneal nerve. Common causes include stroke, multiple sclerosis, or trauma to the knee or lower leg. Patients may present with a steppage gait, where they lift their knee higher than normal to avoid dragging the foot. The condition can significantly impact mobility and quality of life, necessitating interventions such as physical therapy, orthotic devices, or surgical procedures to correct the underlying issue or improve function. Corrective procedures may include tendon transfers or nerve decompression, depending on the etiology. Accurate diagnosis and coding are crucial for appropriate management and reimbursement.
Detailed neurological examination findings, imaging results, and history of neurological disorders.
Patients with stroke, multiple sclerosis, or peripheral neuropathy presenting with foot drop.
Ensure documentation reflects the neurological basis for foot drop to support coding.
Surgical notes, imaging studies, and details of any orthopedic interventions.
Patients with traumatic injuries to the knee or lower leg resulting in foot drop.
Document any corrective procedures performed and their outcomes.
Performed for decompression of the peroneal nerve in cases of foot drop.
Surgical notes detailing the procedure and indications.
Orthopedic or neurosurgical documentation must support the need for surgery.
Common causes include neurological conditions such as stroke or multiple sclerosis, traumatic injuries to the knee or lower leg, and conditions affecting the peroneal nerve.
