Direct infct of unsp hip in infec/parastc dis classd elswhr

This code signifies an inflammatory condition affecting the hip joint, specifically caused by a direct infection originating from an infectious or parasitic disease. The underlying infectious agent is classified elsewhere, meaning this code is used when the primary infection is known but the specific hip joint involved is not documented.

Use this code when documentation confirms a direct infectious arthritis of the hip, and the causative infectious or parasitic disease is identified and coded separately, but the laterality of the affected hip is unspecified. This code is appropriate when the medical record indicates "infectious hip arthritis" or "septic hip" due to a systemic infection, without specifying left or right.

• Always sequence the code for the underlying infectious or parasitic disease first, as this code is an "in diseases classified elsewhere" code.
• Avoid using this code if the laterality of the affected hip (left or right) is documented; instead, use the more specific M01.X51 or M01.X52.
• Ensure documentation clearly states a direct infection of the hip, not just an inflammatory response secondary to a systemic infection without direct joint involvement.
