Spontaneous rupture of extensor tendons, unspecified forearm
ICD-10 M66.239 is a billable code used to indicate a diagnosis of spontaneous rupture of extensor tendons, unspecified forearm.
Spontaneous rupture of extensor tendons in the forearm is a condition characterized by the unexpected tearing of the extensor tendons, which are responsible for extending the fingers and wrist. This condition can occur without any apparent trauma or injury, often seen in individuals with underlying conditions such as rheumatoid arthritis or chronic tenosynovitis. The rupture may lead to significant functional impairment, including loss of grip strength and difficulty in performing daily activities. Symptoms typically include sudden pain, swelling, and inability to extend the affected fingers. Diagnosis is primarily clinical, supported by imaging studies such as ultrasound or MRI to confirm the rupture and assess the extent of tendon damage. Treatment options may vary from conservative management, including splinting and physical therapy, to surgical intervention for tendon repair or reconstruction, depending on the severity of the rupture and the patient's overall health status.
Detailed operative reports, imaging studies, and pre-operative assessments.
Patients presenting with sudden wrist pain and inability to extend fingers, often following a history of chronic joint issues.
Documentation must clearly indicate the spontaneous nature of the rupture and any relevant surgical interventions.
Comprehensive patient history, including previous joint issues and current medications.
Patients with autoimmune disorders presenting with tendon ruptures due to underlying inflammation.
Consideration of systemic conditions that may predispose patients to tendon ruptures.
Used when surgical repair is performed following a spontaneous rupture.
Operative report detailing the procedure and findings.
Orthopedic surgeons must document the extent of the rupture and the surgical approach taken.
The primary cause is often related to underlying conditions such as rheumatoid arthritis or chronic tenosynovitis, which weaken the tendon structure over time.
