Other synovitis and tenosynovitis, left upper arm

This code signifies inflammation of the synovial membrane (synovitis) or the tendon sheath (tenosynovitis) affecting the left upper arm, excluding specific types of synovitis or tenosynovitis classified elsewhere. It indicates a non-infectious inflammatory process causing pain, swelling, and impaired function in the left upper arm region.

Use this code when documentation specifies synovitis or tenosynovitis of the left upper arm that is not otherwise specified or classified under more specific codes. This includes conditions like non-specific tendinitis with tenosynovitis or inflammatory conditions of the joint capsule not meeting criteria for other diagnoses. Supporting documentation should clearly state the diagnosis and laterality.

• Ensure the documentation explicitly states "left upper arm" to justify this laterality.
• Differentiate from more specific codes for tenosynovitis, such as De Quervain's tenosynovitis, which have their own unique codes.
• Always review the medical record for any underlying cause or associated conditions that may require additional coding.
