Spontaneous rupture of extensor tendons, lower leg
ICD-10 M66.26 is a billable code used to indicate a diagnosis of spontaneous rupture of extensor tendons, lower leg.
Spontaneous rupture of extensor tendons in the lower leg is a condition characterized by the unexpected tearing of the extensor tendons, which are responsible for extending the toes and foot. This injury often occurs without any preceding trauma or significant stress, making it a unique clinical presentation. Patients may experience sudden pain, swelling, and loss of function in the affected area. The condition can be associated with underlying synovial disorders, such as tenosynovitis, which may weaken the tendon structure over time. Diagnosis typically involves a thorough clinical examination, imaging studies like ultrasound or MRI, and sometimes diagnostic injections to assess tendon integrity. Treatment options range from conservative management, including rest and physical therapy, to surgical intervention for tendon repair or reconstruction, depending on the severity of the rupture and the patient's functional needs. Accurate coding is essential for proper reimbursement and tracking of treatment outcomes.
Detailed operative notes, imaging results, and pre-operative assessments.
Patients presenting with acute pain and swelling in the lower leg, often after minimal or no trauma.
Ensure documentation reflects the spontaneous nature of the rupture and any prior history of tendon issues.
Functional assessments, therapy progress notes, and patient-reported outcomes.
Patients undergoing rehabilitation post-surgery or conservative management for tendon ruptures.
Document the patient's functional limitations and response to therapy to support coding.
Used when surgical repair is performed following a spontaneous rupture.
Operative report detailing the procedure, indications, and post-operative care.
Orthopedic surgeons should ensure that the surgical notes clearly indicate the diagnosis and rationale for the procedure.
Spontaneous tendon rupture occurs without significant trauma or injury, often due to underlying conditions, while traumatic rupture is a direct result of an injury or excessive force applied to the tendon.
