Blister (nonthermal) of vagina and vulva, subs encntr

This code signifies a non-burn related fluid-filled lesion on the external female genitalia or within the vagina. These blisters are typically caused by friction, pressure, or certain skin conditions, rather than heat exposure.

Apply this code when documenting follow-up care for a patient presenting with a non-thermal blister affecting the vulva or vagina. This includes subsequent visits for monitoring, wound care, or evaluation of healing after the initial encounter.

• Ensure the documentation clearly states the blister is non-thermal in origin.
• Confirm this is not the initial encounter for the blister; otherwise, an initial encounter code should be used.
• Specify the exact location (vagina or vulva) if possible, though this code covers both.
