Other infective (teno)synovitis, unspecified hip

This code represents inflammation of the synovial membrane and/or tendon sheath in the hip joint due to an unspecified infectious agent. It indicates an inflammatory process affecting the hip's tendons and/or synovium, where the specific pathogen causing the infection has not been identified.

Use this code when documentation clearly states "infective synovitis" or "infective tenosynovitis" of the hip, but the causative organism (e.g., bacterial, viral, fungal) is not specified. It is appropriate for cases where the infection is suspected or confirmed, but further microbiological identification is pending or was not performed.

• Do not use this code if the specific infectious agent is known; instead, use a more precise code from categories M00-M02.
• Ensure the documentation specifies "infective" or "septic" to differentiate from non-infectious inflammatory conditions.
• Always sequence this code after any underlying systemic infection if applicable and documented.
