Blister (nonthermal) of right hand, initial encounter

This code signifies a non-heat-related fluid-filled lesion on the right hand. This type of blister can result from friction, pressure, or contact with irritants, but not from burns or frostbite. The "initial encounter" designation indicates that the patient is receiving active treatment for this specific condition for the first time.

Apply this code when documenting a patient presenting with a blister on their right hand that is not caused by thermal injury (e.g., a burn or frostbite). This is appropriate for the initial visit where the blister is diagnosed and treatment is initiated, such as drainage, dressing application, or patient education.

• Ensure the blister is explicitly documented as non-thermal and located on the right hand.
• Verify that this is the first time the patient is being treated for this specific blister to justify the "initial encounter" extension.
• For subsequent visits related to the healing of this same blister, a different encounter character will be required.
