Blister (nonthermal) of unspecified shoulder, subs encntr

This code signifies a non-burn related blister located on an unspecified part of the shoulder, indicating that the patient is receiving follow-up care for this condition. The blister is not caused by heat, chemicals, or radiation, but rather by friction, pressure, or other mechanical forces.

Use this code when documenting subsequent encounters for a patient being treated for a blister on the shoulder that was not caused by a thermal injury. This applies to situations such as wound checks, dressing changes, or monitoring the healing process of an existing non-thermal shoulder blister.

• Ensure the documentation clearly states the blister is non-thermal and located on the shoulder.
• The "D" seventh character indicates a subsequent encounter, meaning the initial treatment for the blister has already occurred.
• Avoid using this code for initial encounters; a different seventh character would be appropriate for the first visit.
