If your insurer denies coverage for a procedure or medication, you may be able to identify the correct billing code and request that the provider refile the claim. If you have questions about the codes used, checking with the medical provider and insurer may save you some research time.
One type of billing code error is known as upcoding. This is when the provider bills for a longer session than was provided (for example, being billed for a 60-minute session when you were only seen for 15 minutes). Another common error is known as unbundling, which refers to using codes for each component part of a procedure rather than a single code that covers them all.
