Spontaneous rupture of flexor tendons, right shoulder

This code signifies a non-traumatic tear of the flexor tendons in the right shoulder. This condition typically results from degenerative changes within the tendon, rather than an acute injury or external force. It represents a spontaneous disruption of the tendon fibers.

Apply this code when documentation clearly indicates a spontaneous, non-traumatic rupture of one or more flexor tendons in the patient's right shoulder. Supporting documentation should rule out acute injury and often describes pre-existing degenerative changes or chronic overuse. This code is appropriate for initial encounters, subsequent care, and sequelae related to this specific condition.

• Ensure laterality is accurately documented as "right shoulder" to support this specific code.
• Distinguish from traumatic ruptures (S46.011A-S46.991S) which have a different etiology and coding.
• Look for documentation of "spontaneous," "atraumatic," or "degenerative" rupture to justify using this code.
