Blister (nonthermal) of breast, left breast, sequela

This code signifies a non-heat-related blister located on the left breast, indicating that the blister is a residual effect or complication of a previous injury or condition. It describes a chronic or long-term consequence rather than an acute presentation.

Use this code when documenting a patient presenting with a blister on the left breast that is clearly identified as a sequela, meaning it's a lasting effect from an earlier, resolved condition or injury. This would apply after the acute phase of the original injury or condition has passed.

• Ensure documentation clearly states the blister is on the left breast and is a sequela.
• Always code the underlying cause of the original injury or condition that led to the sequela, if known and still relevant.
• Distinguish from acute blisters (e.g., from trauma, friction) which would use different codes.
