Workers’ Compensation Provider Billing FAQs
A workers’ compensation provider is a doctor, hospital, or other healthcare provider that provides services to injured workers who are covered by the Workers’ Compensation Law.
You may come across several billing terminology and this section will help answer some of your questions. This section is based on New York state workers compensation guidelines.
If you’re billing for any services that are not related to workers’ compensation, those charges should be billed separately from the workers’ compensation claims that you submit to your insurance company. For example, if you’re filing a claim for an injured worker but also treating them for another condition like diabetes, then those billings should be separated so that only the portion related to their injury is paid for through workers’ compensation insurance benefits and not their health insurance plan as well.
