Hospital and Physician Financing
Public and private hospitals receive payment from both public and private financing sources. Hospitals are typically paid through a diagnostic-related group (DRG), which assigns a set payment amount for a particular condition or treatment sequence. Inpatient DRGs are widely used by the Centers for Medicare & Medicaid Services (CMS) and by many private payers as a payment scheme for hospitals. Rather than paying the hospital for a line-item list of procedures and medications, Medicare pays the hospital a fixed amount based on the DRG, regardless of the actual cost of treatment. The DRG-based payments cover accommodation costs in a hospital (ie, room and board, facility costs, etc), procedure costs, support staff (nurses, technicians, etc), and drug/medical device costs; however, this system does not include physician fees. In the outpatient setting, Ambulatory Payment Classification (APC) codes are used by the hospital system for billing and reimbursement. These APC codes represent a fee-for-service style of billing, rather than the capitated, cost-based style of DRGs.5
Physician fees are not included within DRG (inpatient) or APC (outpatient) codes. When billing for physicians and other clinician fees, Current Procedural Terminology (CPT) codes are used and are billed under the name of the provider rather than the hospital. CPT codes may be used in both inpatient and outpatient settings and indicate a fee-for-service healthcare reimbursement structure.
Private insurers pay hospitals based on DRGs, case rates, per diems, fee-for-service, and/or discounted fee-for-service schemes. On average, these payments exceed the hospital’s costs of providing the underlying services. Conversely, hospitals, on average, are reimbursed less than the costs of services for Medicare, Medicaid, and uninsured patients.
