Blister (nonthermal) of scrotum and testes, subs encntr

This code signifies a non-heat-related blister affecting the scrotum and/or testes, encountered during a follow-up visit for care after the initial treatment. These blisters are typically caused by friction, chemical irritants, or allergic reactions, rather than burns or frostbite.

Apply this code when documenting subsequent care for a patient presenting with a blister on the male genitalia that was not caused by thermal injury. This is appropriate for office visits, wound care appointments, or other follow-up encounters after the initial diagnosis and treatment of the blister.

• Ensure the blister is explicitly documented as nonthermal to differentiate from burn injuries.
• Verify that the encounter is indeed a subsequent visit for ongoing care related to the blister.
• Consider additional codes for the underlying cause of the blister if known and relevant to the encounter.
