Flail joint, unspecified shoulder

This code describes a flail joint affecting an unspecified shoulder. A flail joint is characterized by abnormal, excessive, and uncontrolled movement due to severe ligamentous and/or muscular instability, often resulting from paralysis or extensive soft tissue damage. In the shoulder, this leads to a loss of functional stability and control.

Use this code when documentation clearly indicates a diagnosis of a flail shoulder joint, but the specific laterality (left or right) is not documented. This typically occurs in cases of severe rotator cuff tears, brachial plexus injuries, or other conditions leading to complete loss of shoulder integrity and control. The physician's notes should explicitly state "flail shoulder" without specifying left or right.

• Avoid using this code if laterality (left or right shoulder) is specified in the medical record; instead, select the more specific code.
• Ensure documentation supports the "flail" nature of the joint, differentiating it from general instability or dislocation.
• Consider sequencing this code with an underlying cause, such as a brachial plexus injury or severe nerve damage, if applicable and documented.
