Arthropathy following intestinal bypass, left shoulder

This code signifies joint disease, specifically affecting the left shoulder, that develops as a complication following surgical alteration of the digestive tract for weight loss or other medical conditions. This arthropathy is often inflammatory and can manifest with pain, swelling, and reduced range of motion in the affected joint.

Apply this code when documentation clearly links left shoulder arthropathy to a history of intestinal bypass surgery. This typically occurs in patients presenting with new-onset joint symptoms after such a procedure, and when other causes of arthropathy have been ruled out. Supporting documentation should include a history of intestinal bypass and clinical findings consistent with inflammatory or reactive arthritis.

• Ensure the documentation explicitly states "left shoulder" and a causal link to intestinal bypass.
• Do not confuse with other types of arthropathy (e.g., osteoarthritis, rheumatoid arthritis) unless they are also present and separately documented.
• Consider sequencing this code after the primary diagnosis if the arthropathy is a manifestation of another underlying condition.
