To dispute a charge you must send a written notice
of the
billing error to the address provided on your credit card statement providing your name, address, account number and details
of the
error such as the date,
type and amount
of the
error.
The easiest way to avoid this
type of error is to make sure that you always have the most updated versions
of your coding books, and check your commonly
billed codes each year to see if they have changed.
