Answer: For proper diagnosis coding, you should use two separate diagnosis codes for a prevasectomy exam and the actual vasectomy procedure. Link V25.09 (Encounter for contraceptive management; general counseling and advice; other) to the prevasectomy examination code, and link V25.2 (... sterilization) to the vasectomy code (55250, Vasectomy, unilateral or bilateral [separate procedure], including postoperative semen examination[s]).
Double-check with your carrier as to which V code it requires for payment for the vasectomy, because carriers' coding guidelines will vary. Many carriers will only accept V25.2, and, therefore, you must use this ICD-9 code for the preoperative evaluation as well as the vasectomy.
