Other infective (teno)synovitis, left ankle and foot

This code describes inflammation of the synovial membrane lining a tendon sheath, or the synovial membrane of a joint, in the left ankle and/or foot, when the inflammation is caused by an infection. This condition can lead to pain, swelling, and restricted movement in the affected area.

Use this code for patients diagnosed with an infectious tenosynovitis or synovitis specifically affecting the left ankle or foot. Documentation should clearly state the infectious etiology (e.g., bacterial, fungal) and the precise anatomical location. This code is appropriate when the infection is not specified as pyogenic or tuberculous.

• Ensure documentation specifies "infective" and not just "inflammatory" to differentiate from non-infectious causes.
• Confirm the laterality is explicitly documented as "left" for the ankle and/or foot.
• Code an additional code to identify the infectious organism, if known (e.g., B95-B97).
