Blister (nonthermal), unspecified great toe, subs encntr

This code signifies a non-burn-related blister located on an unspecified great toe. It indicates that the patient is presenting for follow-up care or treatment of this specific blister after the initial encounter.

Apply this code when a patient returns for a subsequent visit related to a blister on their great toe that was not caused by heat or cold. This includes scenarios such as wound care, re-evaluation, or dressing changes for an existing non-thermal great toe blister.

• Ensure the documentation clearly states the blister is non-thermal and located on the great toe.
• Verify that the encounter is not the initial presentation of the blister.
• Do not use this code for blisters caused by burns or frostbite; those have specific codes.
