Final answer:
To file a claim with a liability payer, healthcare providers generally use the CMS-1500 form. This form allows non-institutional providers to seek reimbursement from liability insurance, unlike the CMS-1450, which is used by institutional providers, or First Report of Injury that applies to workers' compensation reports.
Step-by-step explanation:
To file a claim with a liability payer, the appropriate type of form used is typically the CMS-1500. This form is the standard claim form used by healthcare providers to bill Medicare carriers and medical equipment suppliers. It is also widely used for billing various kinds of health insurance claims by providers, including liability coverages like auto insurance or workers' compensation. Therefore, for most non-institutional providers and suppliers, the CMS-1500 is the specified form to submit a claim to a liability payer when seeking reimbursement.
In contrast, the CMS-1450 (or UB-04) form is primarily used by institutional providers such as hospitals. The First Report of Injury form is typically used to report a workplace injury to workers' compensation, and a Patient billing statement is given to patients to inform them of the amount due for services provided, not to file a claim with an insurance entity.
