Bariatric surgery status

This code indicates that a patient has a history of having undergone bariatric surgery, such as gastric bypass, sleeve gastrectomy, or adjustable gastric banding. It signifies a permanent change in the patient's anatomy and physiology due to a surgical procedure performed to treat obesity. This status can impact future medical management and potential complications.

Use this code for patients who have previously had bariatric surgery and are presenting for follow-up care, management of related conditions, or for any other medical encounter where their surgical history is relevant to their current health status. It is appropriate when the bariatric surgery itself is not the primary reason for the encounter, but rather a significant part of the patient's medical history.

• Always assign this code as a secondary diagnosis, never as a primary diagnosis, as it represents a status, not an acute condition.
• Do not use this code if the patient is pregnant, in childbirth, or puerperium and the bariatric surgery status is complicating these conditions; refer to the O99.84 exclusion.
• Distinguish from Z98.0 (intestinal bypass and anastomosis status), which is a broader category and does not specifically denote bariatric surgery.
