Arthritis due to other bacteria, right ankle and foot

This code signifies an inflammatory joint condition affecting the right ankle and foot, specifically caused by a bacterial infection other than those typically classified as pyogenic or specific infectious diseases. This form of arthritis results from the body's immune response to bacterial presence within the joint space or surrounding tissues.

Apply this code when documentation clearly indicates arthritis of the right ankle and foot, and laboratory or clinical findings confirm a bacterial etiology that is not otherwise specified (e.g., not gonococcal, tuberculous, etc.). This is appropriate for cases of septic arthritis where the causative organism is identified as a bacterium but does not fall under more specific infectious arthritis codes.

• Ensure the medical record specifies "right ankle and foot" and confirms a bacterial cause.
• Do not use this code for arthritis due to specific organisms (e.g., tuberculosis, salmonella); use more specific codes from Chapter 1.
• Always sequence a code for the specific bacterial organism (B95.- or B96.-) as a secondary diagnosis, if known.
