Postdysenteric arthropathy, unspecified hip

This code represents joint inflammation and pain in an unspecified hip that develops after a bout of dysentery. It is a reactive arthritis, meaning the joint inflammation is triggered by an infection elsewhere in the body, in this case, the gastrointestinal tract. The arthropathy is not due to direct bacterial invasion of the joint but rather an immune response.

Use this code when documentation clearly indicates a diagnosis of reactive arthritis affecting the hip, specifically attributed to a preceding dysenteric infection. The patient's history should include a recent episode of dysentery, and the hip pain/inflammation should be consistent with a post-infectious etiology.

• Ensure documentation specifies "postdysenteric" and "arthropathy" of the hip.
• If the specific hip (left or right) is documented, use the more specific code (M02.151 or M02.152).
• Code the underlying dysenteric infection if it is still active or relevant to the current encounter, following sequencing guidelines.
