Outpatient surgery is also referred to as "same-day" surgery and "ambulatory" surgery.

Many surgeries today can be performed on an outpatient basis and do not require admission to the hospital. Examples include but are not limited to, knee and hip arthroplasty/replacement, removal of non-malignant growths, cataract surgery, and laparoscopies.

When having surgery in a hospital facility, however, check with the provider about the expected inpatient or outpatient status following the surgery. Unless the provider writes an order for inpatient admission to the hospital, the status will be outpatient, and payment of cost-sharing amounts for outpatient surgery is required. Even with an overnight hospital stay, it may still be considered outpatient.

Medicare covers the facility service fees related to approved surgical procedures provided in an ambulatory surgical center (an outpatient facility where surgical procedures are performed, and the patient is expected to be released within 24 hours). Except for certain preventive services, the member pays 20% of the Medicare-ap[proved amount to both the ambulatory surgical center and the provider who treats them. The Part B deductible applies. The member pays all of the facility service fees for procedures Medicare doesn't cover in ambulatory surgical centers.

Bariatric surgery

Medicare covers some bariatric surgical procedures, like gastric bypass surgery and laparoscopic banding surgery, when certain conditions are met related to morbid obesity. For information on coverage click here.

Second surgical opinions

Medicare covers a second surgical opinion in some cases for medically necessary surgery that isn't an emergency. In some cases, Medicare even covers third surgical opinions.
