Spontaneous rupture of flexor tendons, right upper arm
ICD-10 M66.321 is a billable code used to indicate a diagnosis of spontaneous rupture of flexor tendons, right upper arm.
Spontaneous rupture of flexor tendons in the right upper arm is a condition characterized by the unexpected tearing of the flexor tendons, which are responsible for bending the fingers and wrist. This injury can occur without any apparent trauma or overuse, often linked to underlying conditions such as rheumatoid arthritis or tenosynovitis. The flexor tendons are encased in a synovial sheath that can become inflamed, leading to increased friction and eventual rupture. Symptoms typically include sudden pain, swelling, and loss of function in the affected area. Diagnosis is primarily clinical, supported by imaging studies such as ultrasound or MRI to confirm the rupture and assess the extent of damage. Treatment often involves surgical intervention to repair the torn tendon, followed by rehabilitation to restore function. Accurate coding is essential for proper management and reimbursement, as it reflects the complexity of the injury and the required treatment.

Surgical repair of ruptured flexor tendons following spontaneous rupture.
Ensure documentation reflects the surgical approach and any complications.
Comprehensive history of underlying conditions, treatment plans, and response to therapy.
Management of spontaneous tendon ruptures in patients with rheumatoid arthritis.
Document the relationship between inflammatory conditions and tendon integrity.
Used when surgical repair is performed following a spontaneous rupture.

Orthopedic surgeons should document the specific tendon repaired.
Spontaneous tendon rupture occurs without any significant trauma or injury, often due to underlying conditions, while traumatic rupture results from a specific injury or excessive force applied to the tendon.
