Blister (nonthermal), right thigh, subsequent encounter

This code signifies a non-burn related fluid-filled lesion on the right thigh that is being treated or evaluated after the initial encounter. It indicates a blister that has developed due to friction, pressure, or other non-thermal causes.

Apply this code when documenting follow-up care for a patient presenting with a blister on their right thigh, where the blister was not caused by heat or cold. This includes scenarios such as wound checks, dressing changes, or further evaluation of a previously diagnosed non-thermal blister.

• Ensure the documentation clearly specifies the right thigh as the affected anatomical site.
• Verify the blister etiology is explicitly non-thermal to differentiate from burn codes.
• Confirm this is a subsequent encounter, indicating ongoing care rather than the initial presentation.
