Acute lymphangitis of trunk, unspecified

This code describes an acute bacterial infection of the lymphatic vessels located on the patient's trunk, characterized by red streaks extending from an infection site. It indicates inflammation of the lymphatic channels without specifying the underlying cause or specific location on the trunk.

This code is appropriate when documentation clearly states acute lymphangitis affecting the torso, abdomen, back, or chest, and the specific site is not further detailed. It should be used when the physician's diagnosis explicitly identifies lymphangitis of the trunk without further specificity.

• Ensure documentation specifies "acute" and "trunk" for accurate code assignment.
• Do not use this code if a more specific anatomical site (e.g., arm, leg) is documented; refer to the appropriate body site subcategory.
• Always code the underlying infection (e.g., cellulitis, wound infection) first, if known, as lymphangitis is often a complication.
