Blister of right eyelid and periocular area, subs

This code describes a non-thermal blister located on the right eyelid or the surrounding periocular region. This injury is not caused by heat, cold, or chemical exposure, but rather by friction, pressure, or other mechanical trauma. The "D" seventh character indicates that this is a subsequent encounter for the injury, meaning the patient is receiving routine care during the healing phase.

Use this code for follow-up visits where a patient is being treated for a non-thermal blister on their right eyelid or periocular area. Documentation should clearly state the location of the blister, confirm its non-thermal origin, and indicate that the visit is for ongoing care, such as wound checks, dressing changes, or medication refills related to the initial injury.

• Ensure documentation specifies "right" eyelid/periocular area; laterality is crucial.
• Confirm the blister is "non-thermal"; if caused by heat/cold/chemical, a different code from the T20-T32 series would be appropriate.
• The "D" seventh character is for subsequent encounters; use "A" for initial encounters and "S" for sequela.
