Spontaneous rupture of flexor tendons, left shoulder

This code signifies a non-traumatic tear of the flexor tendons in the patient's left shoulder. This typically involves tendons such as the biceps brachii or subscapularis, where the rupture occurs without an acute external force or injury. The tear is often a result of degenerative changes or chronic overuse.

Use this code when documentation clearly indicates a spontaneous (non-traumatic) rupture of one or more flexor tendons in the left shoulder. This diagnosis is supported by imaging studies (e.g., MRI) confirming the rupture and a patient history that rules out an acute traumatic event.

• Ensure documentation specifies "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Verify laterality (left shoulder) is explicitly stated in the medical record.
• Distinguish from tendinitis or partial tears, as this code is for a complete rupture.
