Abscess of tendon sheath, right upper arm

This code signifies an infection with pus formation within the synovial sheath surrounding a tendon in the patient's right upper arm. This condition typically presents with localized pain, swelling, redness, and warmth, often limiting the range of motion of the affected limb.

Apply this code when documentation clearly indicates a diagnosis of a tendon sheath abscess located in the right upper arm. Supporting documentation should include physician notes detailing the presence of an abscess, its specific location, and laterality.

• Ensure the documentation specifies "abscess" and not just "tendinitis" or "tenosynovitis" without pus formation.
• Verify the laterality (right) and anatomical site (upper arm) are explicitly stated.
• Consider additional codes for the causative organism if identified and documented.
