Other instability, unspecified shoulder

This code signifies a general lack of stability in the shoulder joint, not further specified as recurrent, traumatic, or atraumatic. It indicates that the shoulder joint is prone to displacement or subluxation due to ligamentous laxity or other structural issues, without a definitive cause or specific type of instability documented.

Use this code when documentation indicates "shoulder instability" without further detail regarding the type (e.g., multidirectional, anterior, posterior) or cause (e.g., traumatic, atraumatic, recurrent). This code is appropriate when the physician has not specified the laterality of the affected shoulder.

• Avoid using this code if the documentation specifies the type or cause of instability; instead, use a more specific code from the M24.2 or M24.3 series.
• Always query the provider for laterality (right, left, bilateral) if not documented, as more specific codes exist.
• This code should be used sparingly, primarily when no further information about the instability is available after thorough review of the medical record.
