Cytologic evidence of malignancy on smear of vagina

This code indicates the presence of malignant cells detected during a microscopic examination of a vaginal smear, typically a Pap test or liquid-based cytology. It signifies an abnormal finding suggestive of cancer or high-grade pre-cancerous lesions within the vagina.

Apply this code when pathology reports or cytology results explicitly state "cytologic evidence of malignancy" or "malignant cells present" from a vaginal smear. This is often a follow-up finding after an abnormal cervical Pap test or in patients with a history of gynecological malignancy.

• Do not use this code for abnormal cervical cytology; refer to codes in the R87.61x series for cervical findings.
• This code represents a finding, not a definitive diagnosis of cancer; further workup (e.g., biopsy) is usually indicated.
• Sequence this code after any definitive diagnosis of vaginal malignancy if known, or as the primary diagnosis if the malignancy is not yet confirmed.
