Spontaneous rupture of extensor tendons, right shoulder

This code signifies a non-traumatic tear of the extensor tendons in the right shoulder. This typically involves the rotator cuff tendons (supraspinatus, infraspinatus, teres minor, subscapularis) or other extensor tendons of the shoulder, occurring without an acute injury or external force. The rupture is considered spontaneous, often due to degenerative changes or chronic overuse.

Apply this code when documentation clearly indicates a spontaneous, non-traumatic rupture of the extensor tendons of the right shoulder. This diagnosis is supported by imaging studies (e.g., MRI, ultrasound) confirming a full or partial thickness tear in the absence of a specific injury event. It is appropriate for conditions like degenerative rotator cuff tears that present acutely without a fall or direct trauma.

• Ensure documentation specifies "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Laterality (right shoulder) is crucial; verify the correct side is documented.
• Do not confuse with M75.121 (Complete rotator cuff tear, right shoulder, not specified as traumatic) if the rupture is explicitly stated as spontaneous.
