M01: Direct infections of joint in infectious and parasitic diseases classified elsewhere

M01.3: Arthritis in other bacterial diseases classified elsewhere

Arthritis in other bacterial diseases classified elsewhere, generally refers to inflammation of the joints caused by bacterial infections sourced from different areas within the body. This is not a general or primary arthritis, but occurs as a secondary complication of another, distinct bacterial disease. The bacteria can reach the joint through the bloodstream from places like the skin, heart, or urinary tract. Signs of this form of arthritis can present themselves as sudden and severe joint pain, joint swelling, redness, and warmth. The inflammation may also lead to a reduction in the range of motion of the affected joint. When not treated promptly, it can produce serious complications such as permanent joint damage and sepsis, a potentially life-threatening infection in the bloodstream.
