Blister (nonthermal) of penis, sequela

This code signifies a non-thermal blister on the penis that is a residual effect or complication of a previous injury or condition. It indicates that the blister is not a new, acute event but rather a long-term consequence.

Use this code when documenting a penile blister that has developed as a sequela of a past injury, infection, or other non-thermal cause. This applies when the original acute condition has resolved, but the blister persists or has manifested later as a direct result of that prior event.

• Ensure documentation clearly links the blister to a previous, resolved condition.
• Do not use for acute, newly formed non-thermal blisters; those would typically fall under acute injury codes.
• Consider additional codes for the underlying cause of the original injury or condition if still relevant for patient care.
