Spontaneous rupture of flexor tendons, left upper arm

This code signifies a non-traumatic tearing of the flexor tendons located in the left upper arm. This rupture occurs without an external force or injury, often due to degenerative changes or underlying systemic conditions. It results in impaired function and pain in the affected limb.

Apply this code when documentation clearly indicates a spontaneous (non-traumatic) rupture of one or more flexor tendons in the patient's left upper arm. Supporting documentation should specify the absence of an acute injury or external force as the cause of the rupture. This code is appropriate for initial encounters, subsequent care, and sequelae related to this specific condition.

• Ensure documentation explicitly states "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Verify the laterality (left upper arm) is clearly documented; separate codes exist for other locations and laterality.
• Distinguish from extensor tendon ruptures, which are classified under a different code series.
