Other reactive arthropathies, unspecified hip

This code signifies an inflammatory joint condition affecting an unspecified hip, triggered by an infection elsewhere in the body, but not directly caused by the infection itself. It represents a sterile arthritis that develops as a reaction to an extra-articular infection, such as a gastrointestinal or genitourinary infection.

Use this code when documentation indicates a reactive arthropathy localized to the hip, without specifying laterality (left or right). This diagnosis is supported by a history of a preceding infection and clinical findings of hip inflammation, such as pain, swelling, and limited range of motion, in the absence of direct joint infection.

• Ensure the documentation clearly states "reactive arthropathy" and specifies the hip as the affected joint.
• Avoid using this code if a specific type of reactive arthropathy (e.g., Reiter's syndrome) or laterality is documented; instead, use a more specific M02.xx code.
• Always code the underlying infection that triggered the reactive arthropathy first, if known and still active.
