Blister (nonthermal), right ankle, subsequent encounter

This code indicates a non-heat-related blister located on the right ankle. It signifies that the patient is receiving follow-up care for this specific injury, rather than the initial treatment. The blister could be due to friction, pressure, or a dermatological condition.

Use this code for subsequent encounters when a patient presents for ongoing management, dressing changes, or evaluation of a blister on their right ankle that was not caused by a burn. This applies to visits after the initial diagnosis and treatment have been rendered. Examples include follow-up appointments for a blister caused by ill-fitting shoes or a skin reaction.

• Ensure the blister is explicitly documented as non-thermal and located on the right ankle.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing phase.
• Do not use for initial treatment of the blister; a code with an "A" seventh character would be appropriate for the initial encounter.
