How do I List More Than One Modifier on an HCFA Claim?

The American Medical Association developed modifiers used in medical billing that provide additional information for the insurance company when placed on the HCFA 1500 form. These modifiers are two-digit numbers and letters that are used in conjunction with procedure codes and give specific details regarding the services performed. For instance, the modifier RT indicates a procedure was performed only on the right side of the body. Modifiers are an extremely important part of medical billing. Using the correct modifier helps ensure the provider is properly paid for the services performed.
