Unspecified synovitis and tenosynovitis, left shoulder

This code signifies inflammation of the synovial membrane (synovitis) or the tendon sheath (tenosynovitis) affecting the left shoulder joint. It indicates that the specific cause or type of inflammation has not been identified or documented.

This code is appropriate when documentation clearly states synovitis or tenosynovitis of the left shoulder but lacks further specificity regarding etiology (e.g., infectious, traumatic, crystal-induced). It should be used when the provider has not specified the exact nature of the inflammation.

• Avoid using this code if the documentation provides a more specific diagnosis for the synovitis or tenosynovitis (e.g., infectious, traumatic).
• Always query the provider for greater specificity if possible, as a more precise diagnosis often leads to a more specific code.
• Differentiate from other shoulder inflammatory conditions like bursitis (M70.32) or capsulitis (M75.02) if documented.
