Bloodborne pathogen exposure claims need to be billed with modifier 22 added to the charges for the source patient.
WSI will cover testing of the source patient when an employee has an injury resulting from a needle stick. Providers should submit the charges and the test results from both the injured worker and the source patient. The charges should be billed separately, with the charges from the source patient identified with modifier 22. The billed charges and the test results from the source patient should also include the claim number of the injured worker and “source patient” in place of the name of the person. The charges for the injured worker would be billed in the normal format, without the modifier, and with the patient’s name and claim number.
