Abscess of tendon sheath, right forearm

This code signifies an infection with pus formation within the synovial sheath surrounding a tendon in the right forearm. This condition typically presents with localized pain, swelling, redness, and warmth along the affected tendon.

Apply this code when documentation explicitly states an abscess of a tendon sheath located in the right forearm. Supporting documentation should include physician notes detailing the diagnosis, location, and laterality of the abscess.

• Ensure laterality (right forearm) is clearly documented; do not default if not specified.
• Distinguish from cellulitis or other soft tissue infections without specific tendon sheath involvement.
• Consider an additional code for the causative organism if identified and documented.
