Spontaneous rupture of flexor tendons, unspecified forearm
ICD-10 M66.339 is a billable code used to indicate a diagnosis of spontaneous rupture of flexor tendons, unspecified forearm.
Spontaneous rupture of flexor tendons in the forearm 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 seen in individuals with underlying conditions such as rheumatoid arthritis, diabetes, or chronic tenosynovitis. The flexor tendons are encased in a synovial sheath that can become inflamed, leading to tenosynovitis, which may weaken the tendon structure. Symptoms typically include sudden pain, swelling, and loss of function in the affected hand or wrist. Diagnosis is often confirmed through physical examination and imaging studies, such as ultrasound or MRI, to assess tendon integrity. Treatment may involve conservative management, including rest and splinting, or surgical intervention to repair the ruptured tendon, depending on the severity and functional demands of the patient. Accurate coding is essential for appropriate reimbursement and tracking of treatment outcomes.
Detailed operative reports, imaging studies, and post-operative notes.
Patients presenting with acute pain and loss of function in the hand, often following a history of chronic tendonitis.
Ensure clear documentation of the surgical approach and any complications encountered during the procedure.
Comprehensive assessments of functional limitations and rehabilitation plans.
Patients requiring rehabilitation post-surgery or those with chronic pain and dysfunction due to tendon rupture.
Document the patient's progress and response to therapy to support ongoing treatment needs.
Used when surgical repair of the ruptured tendon is performed.
Operative report detailing the procedure, findings, and post-operative care.
Orthopedic surgeons should ensure that the surgical approach and any complications are well-documented.
Common causes include underlying conditions such as rheumatoid arthritis, diabetes, chronic tenosynovitis, and degenerative changes in the tendon structure.
