Abscess of tendon sheath, right lower leg

This diagnosis code signifies an infection with pus formation within the synovial sheath surrounding a tendon in the patient's right lower leg. This condition typically presents with localized pain, swelling, redness, and warmth, often impairing the function of the affected tendon. It represents an acute inflammatory process requiring medical intervention.

Apply this code when documentation clearly states an abscess of a tendon sheath located in the right lower leg. Supporting documentation should include physician notes detailing the presence of pus, signs of infection, and the specific anatomical location. This code is appropriate for both initial encounters and subsequent care related to this specific condition.

• Ensure laterality (right) and anatomical site (lower leg) are explicitly documented.
• Distinguish from cellulitis or other soft tissue infections without tendon sheath involvement.
• Consider an additional code for the causative organism if identified and documented.
