Clinical & Coding Specifications

Clinical Context

A 42-year-old female presents to a gynecology clinic with persistent vulvar irritation and multiple small, suspicious lesions noted on exam. The provider performs a focused procedure to excise additional suspicious vulvar or perineal lesions for histopathologic evaluation. The workflow includes pre-procedure counseling and informed consent, targeted local anesthesia of the vulva/perineum, excision of one or more discrete lesions with preservation of cosmetic and functional anatomy, hemostasis, specimen labeling and submission to the pathology laboratory, and postoperative instructions including wound care and signs of infection. The patient is discharged from the ambulatory surgery center or clinic procedure area with a plan for pathology follow-up and potential further treatment depending on results.
