Blister (nonthermal) of unspecified shoulder, init encntr

This code signifies a non-burn related fluid-filled lesion on the skin of the shoulder, where the specific side (left or right) is not documented. It indicates that this is the first time the patient is being treated for this particular blister.

Use this code when a patient presents with a blister on their shoulder that is not caused by heat, chemicals, or radiation, and the medical record does not specify which shoulder is affected. This code is appropriate for the initial assessment and treatment of such a condition.

• Ensure the documentation clearly states the blister is non-thermal.
• Only use this code if the laterality (left or right shoulder) is truly unspecified in the medical record.
• Append additional characters for subsequent encounters (D) or sequelae (S) as appropriate.
