Blister (nonthermal) of left elbow, subsequent encounter

This code signifies a non-burn related blister located on the left elbow. It indicates that the patient is receiving follow-up care for this specific injury, rather than presenting for the initial treatment.

Use this code for subsequent encounters when a patient is being treated for a blister on their left elbow that was not caused by heat or cold exposure. This includes scenarios such as wound checks, dressing changes, or monitoring for healing after the initial presentation.

• Ensure the documentation clearly specifies the left elbow and confirms the blister is nonthermal.
• The "D" seventh character indicates a subsequent encounter; verify this is not the initial treatment.
• Look for documentation of the cause of the blister to rule out thermal injuries, which would require a different code series.
