Arthropathy following intestinal bypass, unspecified hip

This code signifies a joint disease, specifically affecting an unspecified hip, that develops as a consequence of intestinal bypass surgery. This arthropathy is often inflammatory in nature and can manifest with pain, swelling, and stiffness in the affected joint. It is a known, albeit less common, complication of bariatric or other intestinal bypass procedures.

Apply this code when documentation clearly links a patient's hip arthropathy to a history of intestinal bypass surgery, and the specific hip (left or right) is not documented. This diagnosis requires a physician's statement confirming the causal relationship between the bypass and the joint condition.

• Ensure documentation explicitly states "unspecified hip" or does not specify left or right. If a specific hip is documented, use the more precise M02.051 (right) or M02.052 (left) code.
• Code the underlying intestinal bypass procedure history (e.g., Z98.84) as a secondary diagnosis if relevant to the current encounter.
• Do not use this code for arthropathy due to other causes, even if the patient has had intestinal bypass; the link must be established by the provider.
