For decades, fee-for-service (FFS) has been the dominant reimbursement model in U.S. healthcare: providers bill for each service they perform, and volume drives revenue. Value-based care (VBC) changes that by tying reimbursement to patient outcomes, quality metrics, and cost efficiency instead of service volume.
CMS has set a goal of having every person with Traditional Medicare in an accountable care relationship by 2030, and many commercial payers now offer their own value-based contracts. For billing teams, this changes what getting paid correctly means. Part of the payment no longer depends on each claim alone but on quality and cost results measured over a full year, which adds a new layer to the revenue cycle.
For a practice, the useful question is simple: which of your contracts already pay this way, and is your billing set up to handle them?
Fee-for-Service vs. Value-Based Care: The Core Difference
Fee-for-service pays providers for each visit, test, or procedure, regardless of patient outcome. Billing focuses on accurate coding and clean claim submission for each separate service.
Value-based care pays providers based on factors that may include quality metrics, patient outcomes, cost efficiency against benchmarks, and care coordination. These payments sometimes sit alongside per-service billing and sometimes replace it.
As a result, billing teams working under VBC contracts must track data that goes well beyond individual claims, including quality measure performance, patient risk adjustment, and total cost of care benchmarks.
5 Common Value-Based Care Models
1. Pay-for-Performance (P4P)
Providers receive standard fee-for-service payments plus bonuses (or penalties) tied to specific quality metrics, such as preventive screening rates or chronic disease management benchmarks.
2. Shared Savings Programs
Common in accountable care organizations (ACOs), these models give providers a share of the savings when the total cost of care for an attributed patient population comes in below a benchmark while quality targets are met. The Medicare Shared Savings Program (MSSP) is the largest example, and many commercial ACO contracts follow a similar design.
3. Bundled Payments
A single payment covers all services related to one episode of care, such as a joint replacement including pre-op, surgery, and post-op care, instead of separate payments for each service in that episode.
4. Capitation
Providers receive a fixed per-patient, per-month payment no matter how many services are delivered. This shifts the financial responsibility for managing utilization to the practice.
5. Full Risk (Global Risk) Arrangements
The most advanced VBC model. Providers take on both the upside (shared savings) and the downside (shared losses) for the total cost of care of an attributed patient population.
What Changes for Billing Teams Under Value-Based Care
Risk Adjustment and HCC Coding Drive Payment
Under many VBC arrangements, especially Medicare Advantage and ACO models, Hierarchical Condition Category (HCC) coding directly affects the risk-adjusted payment a practice receives. When relevant chronic conditions are not documented and coded, the patient population looks healthier than it is, and reimbursement drops.
Quality Reporting Directly Affects Revenue
Under fee-for-service, quality reporting (such as MIPS reporting under the Quality Payment Program) is often treated as a compliance task separate from billing. Under VBC contracts, quality measure performance determines a meaningful share of reimbursement, so billing and quality reporting teams need to work together.
Total Cost of Care Tracking Needs New Data Sources
Shared savings and capitation models require tracking the total cost of care for an entire attributed population, not only the services one practice bills. That usually means pulling in claims data from the patient’s full care journey, which a standard billing system cannot do on its own.
Patient Attribution Must Be Accurate
In shared savings and capitation models, practices are credited, or held financially responsible, only for patients formally attributed to them. Attribution errors can mean a practice misses credit for savings it achieved, or is charged for costs outside its care.
Claims Data Becomes a Performance Tool
Claims data is no longer only a way to get paid. Under VBC models, it is a core input for finding care gaps, tracking quality measures, and spotting cost savings across a patient population.
Common Challenges When Moving to Value-Based Billing
- Mixed contract complexity: Most practices run fee-for-service and value-based contracts at the same time, so billing teams must apply different rules, metrics, and payment logic depending on each patient’s payer and contract.
- HCC coding gaps: Practices new to risk-adjusted models often underestimate the importance of complete annual HCC coding and miss the chance to reflect true patient complexity.
- Limited analytics capability: Smaller practices often lack the data infrastructure to track total cost of care and quality metrics at the level VBC contracts require.
- Old habits: Staff trained for years to maximize coded services under fee-for-service need to shift their focus to efficiency and outcomes.
How Practices Are Preparing for Value-Based Care
- Investing in HCC coding training and annual wellness visit programs so risk adjustment reflects actual patient complexity
- Building or buying analytics capability to track quality measures and total cost of care alongside claims data
- Auditing attribution rosters regularly under shared savings and capitation contracts
- Cross-training billing staff on quality reporting so billing and compliance teams stop working in isolation
- Partnering with an RCM provider experienced in value-based contracts instead of assuming fee-for-service expertise carries over
That last point matters more than many practices expect. Value-based billing combines coding accuracy with population health data, which is a different skill set from traditional claims processing. FAS Medical Summit supports practices that run mixed fee-for-service and value-based contracts, keeping HCC coding complete and accurate and applying the right reimbursement logic to each contract type as part of our revenue cycle management services.
What Has Not Changed
Fee-for-service billing has not disappeared. Most practices still operate under both models, and every claim still needs to be coded accurately and submitted on time. Value-based care adds a new layer on top of solid medical billing fundamentals. It does not replace them.
What This Means for Your Practice
Value-based care is a real change in how providers get paid. Billing teams now need to look past individual claims to quality performance, risk adjustment, and total cost of care. Practices that invest now in HCC coding accuracy, quality reporting, and analytics will be better prepared as more payers move to value-based contracts.
If your practice does not have in-house analytics or risk adjustment expertise, contact FAS Medical Summit to see how we manage both fee-for-service and value-based billing.
