Understanding Medicare And Medicaid Hospital Reimbursement

how does medicare and medicaid reimburse hospitals

Medicare and Medicaid are government-funded programs that provide healthcare coverage for Americans over 65 or those under 65 with permanent disabilities. Medicare Part A covers hospital expenses for inpatient procedures and hospital stays, while Medicare Advantage (Part C) and Part D have different rules for reimbursement. Medicaid financing is based on a capitated reimbursement rate, which depends on the number of enrolled individuals in a specific area. Reimbursement rates for Medicare services are set by the Centers for Medicare and Medicaid (CMS), and hospitals can choose to accept these predetermined prices, becoming participating providers. The reimbursement process can vary depending on the specific Medicare plan and the provider's relationship with Medicare, with some hospitals opting out of Medicare services altogether.

Medicare Part A, B, C, D, and Medigap

Medicare Part A covers the initial 60 days of a hospital stay, as well as skilled nursing facilities and hospice care. However, this is only applicable after the associated deductible and coinsurance payments have been made. Medicare Part A reimbursement is determined based on whether a provider participates in Medicare services, known as "accepting assignment". The majority of providers are "participating providers", agreeing to accept Medicare's predetermined prices for procedures and tests.

Medicare Part B covers medically necessary services and supplies that meet accepted standards of medical practice to diagnose or treat a medical condition. It also covers preventive services, such as healthcare to prevent or detect illnesses early. If you are part of a Medicare Advantage Plan, your plan may have different rules, but it must provide at least the same coverage as Original Medicare.

Medicare Part C, also known as a Medicare Advantage Plan, is offered by private companies approved by Medicare. These plans provide all of your Part A and Part B coverage and may offer additional coverage, such as vision, hearing, dental, and health and wellness programs. Medicare pays a fixed monthly amount to the companies offering these plans, and they must follow Medicare's rules. However, each plan can have different out-of-pocket costs and rules for accessing services.

Medicare Part D refers to prescription drug coverage, which is often included in Medicare Advantage Plans.

Medigap, or Medicare Supplement Insurance, is extra insurance purchased from a private health insurance company to help cover out-of-pocket costs in Original Medicare. To buy a Medigap policy, you typically need to have both Medicare Part A and Part B. Medigap helps fill in the gaps in Original Medicare coverage, providing additional financial protection for healthcare expenses.

Medicare reimbursement rates

Medicare Part A covers inpatient hospital stays, skilled nursing facilities, and hospice care. It includes the first 60 days of a hospital stay after the associated deductible and coinsurance payments. Providers that fully accept Medicare are known as participating providers and agree to accept predetermined prices for all procedures and tests under Medicare coverage. Non-participating providers do not sign a contract to accept these prices but can still accept Medicare assignments for some procedures.

Reimbursement rates are reviewed annually and updated based on recommendations from a panel of experts. The rates are determined by the Medicare fee schedule, which lists the maximum reimbursements for various treatments. Factors influencing the rates include the complexity of the service, the equipment needed, and inflation. The RBRVS formula, implemented in 1992, calculates payment rates based on physician work, practice expense, and malpractice liability costs, adjusted for geography.

In recent years, there has been concern about Medicare reimbursement rates not keeping up with inflation. Physicians have faced reimbursement cuts, while hospitals have seen rate increases. However, hospitals argue that the updates are still inadequate, making it challenging to invest in patient care, cybersecurity, and their workforce.

Medicare assignment acceptance

When a healthcare provider accepts Medicare assignment, it applies to all Medicare-covered Part A and Part B services. Part A covers inpatient hospital stays, skilled nursing facilities, and hospice care, while Part B covers doctor and outpatient services.

The majority of doctors and providers accept Medicare assignment, but it is important to check before receiving care. If a provider does not accept assignment, they may still accept the Medicare-approved amount on a case-by-case basis or they may opt out of Medicare altogether. In such cases, the patient may be responsible for higher out-of-pocket costs, including the regular coinsurance amount plus an additional charge of up to 15% of the Medicare-approved amount, known as "balance billing".

Medicare reimbursement rates for hospitals are determined by whether they accept assignment or not. Hospitals that accept assignment agree to accept Medicare's predetermined prices for all procedures and tests provided under Medicare coverage. This means that they will only charge Medicare recipients a set price, regardless of their usual charges for a procedure. Billing is based on a preset list of diagnoses and associated billing codes, and reimbursement is based on the severity of the patient's condition and the procedures performed during their hospital stay.

Capitated reimbursement rates

Under the capitated model, the Centers for Medicare & Medicaid Services (CMS), a state, and a health plan enter into a three-way contract to provide comprehensive, coordinated care. In this model, CMS and the state pay each health plan a prospective capitation payment. The capitated model is a way to provide coordinated care to patients through a three-way agreement between CMS, a state, and a health plan. The model aims to improve the quality of care for enrollees, and CMS collects various measures to assess plan performance.

The Medicare-Medicaid Plan (MMP) publishes performance data on certain Medicare Parts C and D quality measures, as well as select CMS core requirements. States interested in participating in the Financial Alignment Initiative had to submit a proposal outlining their approach by October 1, 2011. The capitated model also includes a rate-setting process, with proposed changes to the CMS-HCC Risk Adjustment Model for Payment Year 2017.

Additionally, the managed care regulation requires states to develop valid managed care capitation rates following generally accepted actuarial principles and practices. CMS released the 2024-2025 Medicaid Managed Care Rate Development Guide to assist states in setting rates for managed care programs subject to federal actuarial soundness requirements during the rating periods from July 1, 2024, to June 30, 2025. The guide details CMS' expectations for information in actuarial rate certifications and will be used for CMS' review process.

It is important to note that Medicare reimbursement rates for hospitals vary and are based on the provider's relationship with Medicare and the average cost of care for a specific diagnosis or procedure. Medicare Part A covers hospital expenses when a Medicare recipient is formally admitted, including inpatient surgeries, recovery, and multi-day stays due to illness or injury.

Critical access hospitals

CAHs are eligible for cost-based reimbursement from traditional fee-for-service Medicare. From January 1, 2004, CAHs could receive allowable costs plus 1% reimbursement. However, as of April 1, 2013, CAH reimbursement was reduced by 2% due to sequestration. Some states also allow CAHs to receive cost-based reimbursement from Medicaid.

CAHs have flexible staffing and services, and capital improvement costs are included in allowable costs for determining Medicare reimbursement. They may also have access to ambulance services, though this is not common due to reimbursement structures. CAHs can also benefit from educational resources, technical assistance, and grants through the Flex Program.

Medicare reimbursement rates for hospitals are generally based on whether the provider participates in Medicare services, known as "accepting assignment." Participating providers agree to accept Medicare's predetermined prices for procedures and tests under Medicare coverage. Non-participating providers do not sign a contract to accept these prices but can still accept assignment for specific procedures. The amount for each procedure or test not contracted with Medicare can be up to 15% higher than the approved amount, and patients will need to pay the difference.
