Sporotrichosis arthritis

This code signifies an inflammatory joint condition caused by infection with Sporothrix fungi. It represents a specific manifestation of sporotrichosis affecting the synovial membranes and articular structures, leading to symptoms like pain, swelling, and limited range of motion in the affected joint(s).

Use this code when documentation clearly indicates a diagnosis of arthritis directly attributed to a Sporothrix fungal infection. This typically occurs in patients with a history of sporotrichosis, where the infection has disseminated to the joints, or in cases of direct inoculation into the joint space.

• Ensure documentation specifies "arthritis" as the joint manifestation, not just general joint pain.
• Confirm the causative agent is identified as Sporothrix species.
• Consider sequencing this code after a more general sporotrichosis code (e.g., B42.9) if the arthritis is a complication of a systemic infection.
