Other infective (teno)synovitis, right hip

This code signifies inflammation of the synovial lining of a tendon sheath, or the synovium itself, within the right hip joint, caused by an infectious agent. This condition typically presents with pain, swelling, and restricted movement in the affected hip. It differentiates from non-infectious forms of tenosynovitis.

Apply this code when documentation clearly indicates an infectious etiology for tenosynovitis or synovitis affecting the right hip. Supporting documentation should include physician notes detailing the infection, such as positive cultures, elevated inflammatory markers, or direct visualization of purulent material during surgery. This code is appropriate for both acute and chronic infectious processes.

• Ensure the documentation specifies "infective" or "septic" to differentiate from non-infectious tenosynovitis (M65.8-).
• Verify laterality (right hip) is explicitly stated; do not assume.
• Code the underlying infectious organism (e.g., B95-B97) as an additional diagnosis, if known and documented.
