Blister (nonthermal) of breast, left breast, init encntr

This code signifies the presence of a non-burn-related blister located on the left breast. This lesion is characterized by a fluid-filled sac on the skin, not caused by heat, chemicals, or radiation.

Apply this code when documenting a patient presenting with a blister on their left breast that is explicitly not due to thermal injury. This is appropriate for the initial visit or encounter where the blister is first diagnosed and treated.

• Ensure the documentation clearly specifies "left breast" and rules out thermal etiology.
• Confirm this is the patient's first encounter for this specific blister.
• Consider additional codes for any underlying cause of the non-thermal blister, if known (e.g., insect bite, allergic reaction).
