Blister (nonthermal) of right wrist, subsequent encounter

This code signifies a non-burn related blister located on the right wrist. It indicates that the patient is receiving follow-up care for this specific injury, rather than initial treatment. The blister is not caused by heat, cold, or chemical exposure.

Apply this code when a patient presents for ongoing management, dressing changes, or evaluation of a previously diagnosed non-thermal blister on their right wrist. This would include situations where the blister is healing, or complications like infection are being monitored after the initial encounter.

• Ensure the documentation clearly states the blister is non-thermal and located on the right wrist.
• The "D" seventh character is crucial for subsequent encounters; do not use "A" for initial treatment or "S" for sequela.
• Always review the medical record to confirm the encounter type (initial, subsequent, or sequela) to select the correct seventh character.
