$20,000 Out of Pocket for Laser Ablation Treatment

I have been given the choice of either laser ablation treatment or another round with cryoablation surgery.  The cryoablation treatment is covered by my insurance company, but the laser treatment is not.  The laser treatment would be performed by Dr. Walser at the University of Texas who has only performed approximately 130 laser suergeries but is recommended by Dr. Myers.  If I choose to have another round of cryoablation treatments, my BCBS insurance would cover the cost.

Laser treatment is safer and may save some ability to have still have erections.  Looking for comments back on others who have had any experience with laser ablation treatment - particularly from those who have had experience with Dr. Walser.
