I reside in NY and need to find an insurance plan that will allow for
the Lap Band surgury which is classified as bariatric surgury.  This
is different from gastric bypass - this is a band placed around the
stomach. I currently have medical insurance through my employer but
this is specifically an exclusion.  The insurance code for this
surgury is 43770

I would look closely at the benefits and risks of this procedure. 
Bypass is generally more effective at acheiving the results you want
the first time around.  Although bypass is a bigger operation with a
higher mortality rate, it is much less likely to require several
operations, which would bring these numbers much closer together.
Additionally, you have to consider that people going for the bypass
may be generally unhealthier and this would cause a higher mortality
rate for the procedure.

Remember that your biggest risk is not from the surgery, but from the
risk of being chronically overweight, so you want something that
works.

In any case, good luck with your research.

"Despite its relative technical ease, LAGB has been associated with
several complications. An initial trial of LAGB in the United States
showed disappointing weight loss outcomes and high complication rates,
associated with relatively high revisional surgery rate (40
percent)...The major complications following LAGB include acute stomal
obstruction, band erosion, band slippage/prolapse, port/tubing
malfunction, pouch/esophageal dilatation, esophagitis and
infection...A meta-analysis estimated that, overall, 30-day operative
mortality was 0.1 percent for purely restrictive procedures [LAGB],
0.5 percent for gastric bypass." Complications of bariatric surgery,
