Blister (nonthermal), left great toe, subsequent encounter

This code signifies a non-burn related fluid-filled lesion on the left great toe, specifically indicating a follow-up visit for ongoing care or healing of the blister. It differentiates from initial treatment or sequelae.

Apply this code when a patient presents for a follow-up appointment concerning a blister on their left great toe that was not caused by heat or cold. This includes scenarios such as dressing changes, wound checks, or monitoring the healing process after initial treatment.

• Ensure the blister is explicitly documented as non-thermal and located on the left great toe.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use this code for the initial treatment of the blister or for complications/sequelae.
