Value-based care is no longer a buzzword—it’s the direction the entire healthcare system is moving. And for primary care practices, shared-savings contracts are one of the most tangible expressions of that shift. Done right, they can be a meaningful source of additional revenue. Done wrong—or without a clear understanding of how they work—they can create confusion, missed targets, and money left on the table.

This guide breaks down exactly how shared-savings contracts work, what payers are actually measuring, and how operational decisions you make every day—like how efficiently you retain patients and manage appointments—directly affect your shared-savings outcomes. 

What Is a Shared-Savings Contract?

A shared-savings contract is an agreement between a primary care practice (or a group of practices) and a payer—typically a commercial insurer, Medicare, or Medicaid—in which the practice can earn a portion of the money saved when it delivers care more efficiently than a pre-established benchmark.

The basic idea: if your attributed patient population costs the payer less than expected while meeting quality standards, you share in those savings. If costs exceed the benchmark, you may face no penalty (in upside-only models) or you may owe money back (in two-sided risk models).

Shared-savings arrangements fall under the broader umbrella of value-based care (VBC)—a payment model that ties reimbursement to patient outcomes and cost efficiency rather than the volume of services delivered.

How Shared-Savings Differs From Fee-for-Service

In traditional fee-for-service (FFS) billing, your practice earns revenue for every service rendered—every visit, every lab order, every referral. More visits equals more revenue, regardless of whether those visits improved patient health.

Shared-savings flips that logic. The payer still pays claims on a FFS basis in most arrangements, but at the end of a performance period (usually a year), your practice’s total attributed cost of care is compared to a benchmark. If you came in under that benchmark and met quality thresholds, you receive a portion of the difference as a bonus payment.

This creates a financial incentive to:

• Keep patients healthy so they don’t need expensive interventions
• Coordinate care so patients aren’t bouncing between unnecessary specialists
• Reduce avoidable hospitalizations and ER visits
• Close preventive care gaps before they become costly conditions

Key Terms You Need to Know

Before diving into the mechanics, it helps to have a firm grasp on the terminology payers use in these contracts.

Attributed patients — The patients “assigned” to your practice by the payer for purposes of the shared-savings calculation. Attribution is typically based on which provider a patient sees most often for primary care. This is why patient retention matters so much: patients who drift to other providers may be attributed away from your practice, shrinking your panel and your potential savings.

Benchmark — The expected total cost of care for your attributed population, usually based on historical spending, regional averages, or a blend of both. This is the number your actual costs are measured against.

Total cost of care (TCOC) — The all-in cost of everything your attributed patients use: primary care, specialist visits, labs, imaging, hospitalizations, prescription drugs, and more. You may only directly control a fraction of this, but your referral and care coordination decisions influence a great deal of it.

Shared-savings rate — The percentage of savings you get to keep. Common rates range from 25% to 50% of savings above the threshold, depending on the contract.

Minimum savings rate (MSR) — A floor that savings must exceed before the payer pays out. If you saved $80,000 but the MSR is $100,000, you receive nothing. This protects the payer from paying out small, statistically insignificant variances.

Performance period — Usually 12 months. Savings and quality are calculated at the end of this window.

Quality measures — A set of clinical metrics your practice must meet or exceed to qualify for shared savings. Hitting the cost target alone isn’t enough—quality has to follow.

The Two Models: Upside-Only vs. Two-Sided Risk

Upside-Only (One-Sided) Risk

In this model, your practice can earn shared savings if you come in under the benchmark—but you owe nothing if you exceed it. The payer absorbs all the downside risk.

This is the most common starting point for practices entering value-based contracts for the first time. It’s lower risk, but shared-savings rates are typically lower as well (because the payer is taking on more exposure).

Medicare’s MSSP (Medicare Shared Savings Program) Track 1 is a well-known upside-only model.

Two-Sided Risk

Here, your practice shares in both the upside and the downside. If you generate savings, you earn a portion. If costs exceed the benchmark, you owe a portion back to the payer.

Two-sided models typically come with higher shared-savings rates—sometimes 40–50% or more—because your practice is taking on real financial risk. They require a higher level of data sophistication, care management infrastructure, and financial reserves to absorb a bad year.

Most payers encourage practices to migrate toward two-sided risk over time as they build experience with VBC contracts.

What Payers Are Actually Measuring

Understanding what goes into the benchmark and the quality scorecard is essential to performing well in a shared-savings contract.

Cost Metrics

Payers look at total cost of care, but they also drill into specific cost drivers:

• Inpatient admissions per 1,000 patients — hospitalizations are the single biggest cost lever. Practices that reduce preventable admissions through proactive chronic disease management significantly move the needle.
• 30-day readmission rates — patients who return to the hospital within 30 days of discharge represent a care coordination failure and a major cost spike.
• ER utilization — patients who use the emergency room for conditions that could have been handled in primary care are a red flag. This often reflects access issues—patients who can’t get timely appointments turn to the ER.
• Specialist referral patterns — unnecessary or duplicative specialist referrals add cost without always adding value. Appropriate referrals with clear clinical rationale help.
• Generic vs. brand drug prescribing — medication costs are a significant portion of total spend, and prescribing generics where clinically appropriate helps lower the TCOC.

Quality Measures

Shared savings are almost always contingent on meeting a quality threshold. Common measures include:

• Diabetes control (HbA1c levels)
• Blood pressure management
• Colorectal and breast cancer screening rates
• Depression screening and follow-up
• Medication adherence
• Annual wellness visits completed
• Childhood immunization rates (for family medicine practices)

Falling short on quality can reduce or eliminate your shared-savings payout even if you hit the cost targets. The two work together.

How Your Day-to-Day Operations Affect Shared-Savings Outcomes

Here’s where the connection between practice management and shared-savings performance becomes very concrete. The clinical work matters enormously, but so do the operational systems supporting it.

Patient Retention and Attribution Stability

If patients see your practice inconsistently—or worse, drift to urgent care or other primary care providers—they may be re-attributed away from your panel. That shrinks your attributed population and reduces your potential savings pool. It can also skew your quality metrics if your highest-risk patients are the ones most likely to seek care elsewhere.

Retaining patients means making it easy to stay with your practice. That starts with access: can patients get appointments when they need them? Is online booking available so they don’t have to call and wait on hold? Do they receive reminders that bring them back for preventive care before small issues become costly ones?

Practices that make it easy to book, easy to return, and easy to stay engaged tend to maintain more stable, well-attributed panels—which is the foundation of a successful shared-savings strategy.

Closing Preventive Care Gaps

Care gap closure is one of the highest-leverage activities in shared-savings performance. Every patient who is overdue for a diabetes screening, a blood pressure check, a colorectal cancer screening, or an annual wellness visit represents both a quality gap and a potential cost risk.

Proactive outreach—recalls, reminders, and easy scheduling for follow-up appointments—directly affects how many of those gaps get closed within the performance period.

Reducing Low-Value Utilization

Not every referral, lab order, or imaging study adds clinical value proportional to its cost. Practices that develop discipline around evidence-based referral patterns and appropriate test ordering contribute meaningfully to lower total cost of care. This isn’t about rationing—it’s about ensuring that care is coordinated and well-reasoned rather than reflexive.

Chronic Disease Management

Patients with diabetes, hypertension, heart failure, COPD, and other chronic conditions are disproportionate drivers of cost in any attributed population. Structured, proactive management of these patients—including regular monitoring, medication management, and patient education—prevents the hospitalizations and complications that blow up a TCOC benchmark.

Success in shared-savings contracts depends on more than clinical outcomes. Practices also need reliable technology, accurate billing, secure infrastructure, and access to meaningful performance data. From practice management software and medical billing to cloud hosting, managed IT, cybersecurity, staffing, and consulting, the right operational support can make it easier to succeed in value-based care.

How Vosita Supports Value-Based Care Goals

Shared-savings performance ultimately comes down to two things: keeping patients healthy and keeping them engaged with your practice. Vosita helps primary care practices with both.

When patients can find your practice online, verify their insurance, and book an appointment in minutes—without phone tag or long waits—they’re more likely to choose you and stay with you. That translates directly to more stable attribution, better preventive care completion rates, and reduced drift to urgent care or competing providers.

A well-maintained, easy-to-book practice presence on Vosita helps you:

• Attract new patients who are actively searching for a primary care provider, expanding your attributed panel
• Retain existing patients by making it frictionless to schedule follow-ups and preventive visits
• Reduce no-shows and gaps in care through online booking and appointment management
• Project credibility through a complete profile with reviews, credentials, and availability—so patients choose you over a competitor

In a shared-savings model, every patient who books a preventive visit instead of ending up in the ER is a win. The platforms and systems that make those bookings happen are part of your value-based care infrastructure, whether or not they show up on a quality scorecard.

Negotiating and Evaluating a Shared-Savings Contract

If a payer approaches you about a shared-savings arrangement—or if you’re thinking about pursuing one—here are the key things to evaluate before signing.

Understand how your benchmark is set. Is it based on your own historical spending, regional norms, or a blend? A benchmark based on a high-cost prior year may be easier to beat. One based on already-efficient regional peers may be very hard to exceed.

Know your attributed population’s risk profile. If your panel skews toward older, sicker patients with high chronic disease burden, your TCOC will naturally be higher. Make sure the contract includes adequate risk adjustment so you’re not penalized for taking care of complex patients.

Review the quality measure set. Are these measures you’re already tracking? Are they achievable given your patient population? Some quality measures are easier to influence than others.

Understand the data lag. Payers often report shared-savings performance with a 6–12 month lag. You need good internal data to know how you’re tracking during the performance period, not just at the end.

Ask about care management support. Many payers offer care coordinators, data analytics, and care management tools to practices in value-based contracts. Take advantage of these resources.

Consult a healthcare attorney or consultant before signing any risk-bearing contract. The terms matter enormously, and a small difference in the shared-savings rate or MSR can mean tens of thousands of dollars.

Common Pitfalls to Avoid

Ignoring attribution reports. Payers provide quarterly or monthly reports showing which patients are attributed to your practice. Review these regularly. If high-risk patients you’re actively managing aren’t showing up on your panel, something is off—and it will hurt your performance.

Focusing only on cost without tracking quality. It’s possible to hit a cost target and still miss the quality threshold needed to unlock savings. Run both sets of numbers internally throughout the year.

Taking on two-sided risk too early. If you don’t yet have the care management infrastructure, data analytics capability, and financial reserves to absorb a bad year, start with upside-only. Build your capabilities first.

Underestimating the administrative burden. Shared-savings contracts require reporting, data reconciliation, and care gap tracking. Make sure your team has the bandwidth to manage this—or build it before you sign.

Frequently Asked Questions

How is my practice’s benchmark calculated?

Benchmarks vary by payer and contract. Most are based on some combination of your practice’s historical cost data, regional or national average costs for similar patient populations, and risk adjustment factors that account for your panel’s health status. Always ask the payer to walk you through their specific methodology before signing.

What happens if my costs exceed the benchmark in an upside-only model?

Nothing financially—that’s the nature of upside-only risk. You simply don’t earn shared savings that year. However, repeated underperformance may affect your relationship with the payer or your ability to renegotiate favorable terms.

Can small independent practices participate in shared-savings contracts?

Yes, though it can be harder to do so alone. Many small practices join Independent Practice Associations (IPAs) or Accountable Care Organizations (ACOs) that aggregate patient populations across multiple practices, making the shared-savings model more viable. Learn more about how independent primary care practices are navigating value-based care.

How do I know if shared-savings is right for my practice?

Start by analyzing your current performance on the quality measures payers typically use. If you’re already performing well on preventive care, chronic disease management, and care coordination, you may be leaving money on the table by staying in pure fee-for-service. If there are significant gaps, it may be worth investing in infrastructure before entering a risk contract.

Is shared savings the same as capitation?

No. In capitation, your practice receives a fixed per-member-per-month payment to cover all care for attributed patients—and you absorb the full cost if care exceeds that amount. Shared savings is a performance bonus layered on top of standard fee-for-service claims. They’re different structures with different risk profiles, though both fall under the value-based care umbrella.

The Bottom Line

Shared-savings contracts represent a real opportunity for primary care practices—but only for those who understand the mechanics well enough to act on them. The practices that win in value-based care are the ones that invest in proactive patient management, tight care coordination, and the operational infrastructure that keeps patients engaged and retained.

That infrastructure includes the tools that make it easy for patients to find you, book with you, and keep coming back. Explore how other primary care providers are building smarter, more efficient practices — and how better patient engagement supports both your quality scores and your bottom line.
