Prostate Resection

Lumbar Spinal Fusion, Posterior Column and Approach: No surgeons met the volume requirement of 20 for this procedure.

Cervical (Neck) Spinal Fusion: No surgeons met the volume requirement of 20 for this procedure.

How we calculated these rates: Guided by top researchers and doctors, ProPublica used Medicare data from 2009-2013 to identify cases where a patient died in the hospital or had to be readmitted within 30 days for a problem related to one of these elective procedures. We then calculated complication rates for surgeons, carefully accounting for differences in patient health, age and hospital quality. These rates are calculated using data from Medicare records, which do not include patients with private insurance or in another program like Medicaid. A surgeon’s rate spans all hospitals at which he or she operates and is not unique to a given hospital. Read our methodology »

Important: Some surgeons may no longer be operating at this hospital.

Lumbar Spinal Fusion, Anterior Column, Posterior Approach

Fusing two or more vertebrae in the lower back; performed on the front of the spine, incision in the back (ICD-9-CM code 81.08)

The fusing of two or more vertebrae in the lower back, performed on the front portion of the spine. One of the most common reasons is the narrowing of the space between the vertebrae, which puts pressure on the spinal cord and nerves, causing pain. It can also be done because of disc degeneration or a condition where one bone in the back slides forward over the bone below it.
