Blister (nonthermal) of left front wall of thorax, init

This code signifies a non-burn related fluid-filled lesion on the anterior chest wall, specifically on the left side. It indicates that the blister is a new injury or condition being evaluated and treated for the first time. This type of blister is typically caused by friction, pressure, or a localized skin reaction rather than heat.

Use this code when documenting a patient presenting with a newly formed, non-thermal blister located on the left side of their sternum, ribs, or upper abdomen. This applies to situations such as a blister from ill-fitting clothing, prolonged pressure, or a localized allergic contact dermatitis presenting as a blister. It is appropriate for the initial assessment and treatment of such an injury.

• Confirm the blister's etiology is explicitly documented as non-thermal to differentiate from burn blisters.
• Verify the anatomical location is precisely the "left front wall of thorax" and not another chest area.
• Ensure "initial encounter" is appropriate for the patient's current visit for this specific injury.
