Spontaneous rupture of flexor tendons, unspecified lower leg
ICD-10 M66.369 is a billable code used to indicate a diagnosis of spontaneous rupture of flexor tendons, unspecified lower leg.
Spontaneous rupture of flexor tendons in the lower leg is a condition characterized by the unexpected tearing of the flexor tendons, which are responsible for bending the toes and ankle. This condition can occur without any apparent trauma or injury, often linked to underlying conditions such as chronic tenosynovitis or degenerative tendon changes. Patients may present with sudden pain, swelling, and loss of function in the affected area. The lower leg's flexor tendons, including the tibialis posterior and flexor digitorum longus, are particularly susceptible to rupture due to their anatomical positioning and the mechanical stresses they endure. Diagnosis typically involves a thorough clinical examination and imaging studies, such as ultrasound or MRI, to confirm the rupture and assess the extent of the injury. Treatment may involve conservative management, such as rest and immobilization, or surgical intervention to repair the ruptured tendon, depending on the severity and functional demands of the patient.
Detailed operative reports, imaging results, and post-operative notes are essential.
Surgical repair of ruptured flexor tendons following spontaneous rupture.
Ensure accurate documentation of the surgical technique and any complications.
Comprehensive assessments of functional limitations and rehabilitation plans.
Rehabilitation following tendon repair surgery.
Document the patient's progress and any modifications to the rehabilitation plan.
Used when a surgical repair is performed following a spontaneous rupture.
Operative report detailing the procedure and any complications.
Orthopedic documentation must specify the tendon repaired and the surgical technique used.
Common causes include chronic tenosynovitis, degenerative tendon changes, and systemic conditions such as diabetes or rheumatoid arthritis.
