Blister (nonthermal), left foot, subsequent encounter

This code signifies a non-thermal blister located on the patient's left foot, indicating that the patient is receiving follow-up care for this specific injury. It suggests the initial treatment or diagnosis has already occurred, and the current encounter is for continued management, monitoring, or resolution of the blister.

Apply this code when a patient presents for a subsequent visit related to a blister on their left foot that was not caused by heat or cold. This includes scenarios such as wound checks, dressing changes, or evaluation of healing progress for a previously diagnosed non-thermal left foot blister.

• Ensure documentation clearly specifies "left foot" and "non-thermal" etiology for the blister.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial encounters or for sequelae of the injury; different seventh characters apply for those situations.
