What are the hospital costs involved in surgical removal of an osteochondroma on the distal end of a femur?

Im a 24 year old male. I have learned that with osteochondromas that you want to wait until you are at an age of skeletal growth completion. I have whats called an osteochondroma on the distal end of my left thigh (femur) located just above my knee, angled halfway between the anterior and medial (inside towards my right leg) side of my femur. It is the most common place for osteochondromas to occur. It is close enough to my knee to cause pain upon full flexion. Im serving overseas in afghanistan at the moment and I doubt the army will pay for this type of medical issue so Im curios to see on the civilian side from those who have undergone the procedure what I can expect in medical costs in the surgical removal or the osteochondroma. I understand that cutting through muscle as if it had been located mid way through my femur, would incur higher costs due to longer recovery and physical therapy. Im looking for average cost for the customer who follows the doctors instructions afterwards (im a combat medic who understands fully the importance of FOLLOWING DIRECTIONS) lol. Thank you for your time!
