Blister of unsp external genital organs, male, sequela

This code describes a non-heat-related blister located on the external genital organs of a male, indicating that it is a long-term effect or complication of an initial injury or condition. This could include blisters resulting from friction, chemical exposure, or allergic reactions that have persisted or developed as a consequence of an earlier event.

Use this code when documenting a male patient presenting with a non-thermal blister on the external genitalia, and the medical record clearly indicates that this blister is a sequela. This applies to situations where the original acute injury or condition that caused the blister has resolved, but the blister itself remains as a residual effect.

• Ensure documentation explicitly states the blister is a "sequela" or a "late effect" of a previous injury or condition.
• Confirm the blister is non-thermal; if thermal, a different code category would be appropriate.
• Verify the patient is male and the location is the external genital organs.
