Code __________ reports male-to-female surgery.

The code that accurately reports male-to-female surgery is 55970. This code is specifically designated for gender reassignment surgery or sex change operations from male to female. The use of this code indicates surgical procedures that include orchiectomy (removal of the testes) and vaginoplasty (creation of a vagina), which are essential components of male-to-female transition procedures.

Understanding the context of the other options can provide clarity. Code 55980 relates to a different type of procedure, while 55899 is an unlisted procedure code that does not specifically pertain to gender reassignment. Similarly, 55920 is not associated with male-to-female surgery and is designated for other procedures. Therefore, 55970 is the precise code that captures the essence of the male-to-female surgical transformation, solidifying its selection as the correct answer.
