Blister (nonthermal) of right shoulder, subsequent encounter

This code signifies a nonthermal blister located on the patient's right shoulder. It indicates that the patient is presenting for care related to this specific blister after the initial encounter for the injury or condition that caused it.

Apply this code for follow-up visits concerning a blister on the right shoulder that was not caused by heat or cold exposure. This includes encounters for wound care, monitoring healing, or addressing complications of the blister after the initial diagnosis.

• Ensure the documentation clearly specifies "right shoulder" and "nonthermal" etiology.
• Verify that the encounter is indeed a subsequent visit, not the initial presentation.
• Pair with an external cause code if the etiology of the nonthermal blister (e.g., friction, pressure) is known and documented.
