Blister (nonthermal) of penis, subsequent encounter

This code describes a non-heat-related fluid-filled lesion on the penis, indicating a follow-up visit for a previously diagnosed or treated blister. It signifies ongoing care or assessment for a penile blister that was not caused by burns or frostbite.

Use this code for a patient presenting for a follow-up appointment related to a non-thermal blister on the penis. This includes scenarios such as wound checks, dressing changes, or re-evaluation of healing progress after initial treatment. It is appropriate when the initial injury or condition has already been addressed in a prior encounter.

• Ensure documentation clearly specifies "nonthermal" etiology for the blister.
• Verify that the encounter is indeed subsequent to the initial treatment or diagnosis.
• Distinguish from initial encounters, which would use the 'A' seventh character.
