From 6 April 201 6, if you employ apprentices under the age of 25 you may no longer need to pay employer Class 1 secondary National Insurance contributions (NICs) for them.
For patients not covered by health insurance, the cost of a liver biopsy ranges from $2,000 to $7,000 or more. For patients not covered by health insurance, the cost of a kidney biopsy ranges from $3,000 to $10,000. A biopsy would be considered medically necessary when ordered by a doctor and would almost always be covered by health insurance.
The savings is the difference between cost of open biopsy and of needle biopsy, not biopsy or no biopsy. Still, the difference in cost appears to be more like $3K, not $1K.
