Encounter for other prophylactic surgery

This code describes a patient encounter for a surgical procedure performed to prevent the development of a disease or condition, rather than to treat an existing one. It signifies an intervention undertaken to reduce future risk in individuals who are currently asymptomatic but have identified risk factors.

Use this code when documenting an encounter for prophylactic surgery not specified elsewhere, such as a prophylactic oophorectomy in a patient with a strong family history of ovarian cancer, or a prophylactic mastectomy in a patient with a BRCA gene mutation. It is appropriate for procedures aimed at preventing disease onset.

• Always sequence this code as a secondary diagnosis when the primary reason for the encounter is the prophylactic surgery itself.
• Ensure supporting documentation clearly states the prophylactic nature of the surgery and the specific condition being prevented.
• Do not use for surgeries performed to treat an existing condition, even if it also has a preventative effect.
