Abscess of tendon sheath, left shoulder

This code describes an infection with pus formation within the synovial sheath surrounding a tendon in the left shoulder. This condition typically presents with localized pain, swelling, warmth, and restricted movement of the affected shoulder joint. It is a serious infection that can lead to tendon damage or rupture if not treated promptly.

Use this code when documentation clearly indicates a diagnosis of an abscess specifically affecting a tendon sheath in the left shoulder. Supporting documentation should include physician notes detailing the location, nature of the infection (e.g., purulent drainage, imaging findings consistent with abscess), and laterality.

• Ensure documentation specifies "abscess of tendon sheath" rather than a general tendonitis or tenosynovitis.
• Verify the laterality is explicitly stated as "left shoulder" to avoid incorrect coding.
• Consider an additional code for the causative organism (e.g., B95-B97) if identified and documented.
