Spontaneous rupture of flexor tendons, right thigh

📋Clinical Description

This code signifies a non-traumatic tear of the flexor tendons located in the right thigh. This condition typically occurs without an acute injury, often due to underlying degenerative changes or systemic conditions that weaken the tendon structure.

🎯When to Use

Apply this code when documentation clearly indicates a spontaneous (non-traumatic) rupture of a flexor tendon in the patient's right thigh. This includes cases where the rupture is attributed to chronic overuse, tendinopathy, or systemic diseases like rheumatoid arthritis or diabetes.

💡Coding Tips

Ensure documentation specifies "spontaneous" or "non-traumatic" rupture to differentiate from traumatic injuries.
Verify laterality (right thigh) is explicitly stated in the medical record.
Distinguish from other types of tendon ruptures (e.g., extensor tendons, other body sites) and traumatic ruptures.
