Other synovitis and tenosynovitis, left shoulder

This code signifies inflammation of the synovial membrane or tendon sheath in the left shoulder, excluding conditions like adhesive capsulitis or rotator cuff tendinitis. It encompasses various non-specific inflammatory processes affecting the joint capsule or tendons around the left shoulder joint.

Apply this code when documentation specifies synovitis or tenosynovitis of the left shoulder that doesn't fit more specific diagnoses. This includes conditions like bicipital tenosynovitis or non-infectious inflammatory processes of the shoulder joint capsule. Supporting documentation should clearly indicate the left side and the inflammatory nature of the condition.

• Ensure the documentation explicitly states "left shoulder" to avoid laterality errors.
• Differentiate from more specific shoulder conditions like M75.12 (Rotator cuff tendinitis, left shoulder) or M75.02 (Adhesive capsulitis of left shoulder).
• Always review the medical record for a more precise diagnosis before defaulting to this "other" code.
