Blister (nonthermal) of bilateral front wall of thorax, subsequent encounter

📋Clinical Description

This code describes a non-heat-related blister located on both sides of the anterior chest wall. This indicates a skin lesion characterized by a fluid-filled sac, not caused by burns or frostbite, affecting the front of the rib cage on both the left and right sides.

🎯When to Use

This code is appropriate for follow-up encounters when a patient is receiving ongoing care for a bilateral, nonthermal blister on the front of their chest. This includes situations such as wound checks, dressing changes, or monitoring for healing or complications after the initial injury.

💡Coding Tips

Ensure the documentation clearly specifies a "subsequent encounter" for this specific injury.
Verify the blister is explicitly documented as "nonthermal" and located on the "bilateral front wall of thorax."
Do not use for initial encounters or for blisters caused by burns or frostbite.
