The Hidden Cost of Slow Data Exchange: How Outdated HIEs Are Hurting Reimbursements

Health Information Exchanges were created to break down data silos, but many still run on legacy infrastructure that is slow and incomplete. In today’s value-based care environment, delayed or missing patient data can mean billions in lost or delayed reimbursements. In this article, we review the state of HIEs in the U.S., explain how outdated HIE technology creates data bottlenecks, and show how those gaps translate into financial and operational losses. Finally, we discuss modern approaches – cloud-native, FHIR-based HIE platforms and APIs – that can speed data flow and protect revenue.

The Current HIE Landscape in the U.S.

Most U.S. states now have some form of HIE or statewide network, but usage remains spotty. In fact, 49 of 50 states report having a statewide HIE. Yet providers still struggle to use them in practice. For example, one study found that HIE data was accessed in less than half of patient referrals. 

Nationwide frameworks like the Trusted Exchange Framework are being developed, but rollout is years away. Surveys show about 70% of hospitals can send and receive outside clinical data, but in practice, only ~42% of clinicians report often using it in care delivery. In short, while EHR adoption is high, true interoperability is still far from universal. Providers have incentives to share data, and payers want data (for risk adjustment and quality measurement), but too few HIE links are modern or reliable.

How Legacy HIEs Create Bottlenecks

Outdated HIE technology underlies much of the delay in getting data where it needs to go. Legacy HIE systems were often built for basic HL7 v2 messages or document exchange, not for seamless API-driven sharing. Key problems include:

• Batch-oriented, siloed data. Many older HIEs rely on nightly file feeds or manual data pulls rather than real-time updates. Crucial information may not arrive until hours or days later. Clinicians often have to log into separate portals to fetch data, adding workflow delays.
• “Dumb pipes” and inconsistent data. Legacy HIEs tend to enforce only basic message formats and rarely normalize or code the content. In practice, this means HIEs “act as neutral pipelines,” simply relaying whatever data they get. Without content enrichment, a patient’s allergy list might arrive in five different formats from different providers, leaving downstream systems and clinicians to reconcile “junk” data manually.
• Fragmented coverage. Even within one HIE network, patient records can remain incomplete or duplicated if providers use different systems or codes. Outside the HIE, gaps abound: payers report still receiving many clinical details via fax or PDFs because the electronic exchange isn’t catching everything. For example, hospitals, physician practices, and health plans each use disparate systems – without a universal standard for sharing data – so “data gaps, inconsistent processes, and duplicate information” persist.
• Costly maintenance. Many HIEs still run on on-premises servers and custom interfaces. Industry analysts note that roughly 60% of healthcare organizations continue to use legacy HIE or integration systems approaching end-of-life. These systems demand heavy upkeep – up to 75% of an IT budget in some cases – and they do not scale easily when new partners or use-cases arise.

Together, these limitations mean providers are frequently “stuck with fragmented, low-quality data” just as care is becoming more data-driven.

Slow or incomplete exchange doesn’t just inconvenience clinicians – it degrades the accuracy and timeliness of information that payers and providers need for billing and quality programs.

Financial Impact: Lost Reimbursements and Penalties

Delayed or missing data from outdated HIEs has real cost implications. Under fee-for-service models, claim denials and slow payments eat away at revenue; under value-based contracts, incomplete data can directly reduce shared-savings or bonus payments. Key impacts include:

Claim denials and delayed payments

Revenue-cycle managers know that even minor data errors trigger denials. 

• Missing or inaccurate claim data is the number-one reason for denials, cited by 50% of providers in 2025. 
• Likewise, over a quarter of organizations report that 10% or more of denials come from incomplete patient registration information. 
• Industry analysts warn that this “denial spiral represents billions of dollars in lost or delayed reimbursements”. 

In other words, every time an HIE fails to provide up-to-date patient demographics or clinical details to the billing system, a clean claim can turn into a denial that must be reworked. This has a direct impact on cash flow and staff workload.

Value-based reimbursements and risk adjustment

In value-based care, providers only get full credit if they meet quality and cost benchmarks. That in turn requires comprehensive, timely data on patient outcomes, utilization, and diagnoses. Data gaps hurt on two fronts: first, incomplete patient histories make it impossible to identify eligible patients for outreach, reducing shared savings. Second, inaccurate or delayed data undermines risk adjustment. 

• For instance, if chronic conditions are not captured promptly, a payer’s actuarial risk score may be under-adjusted, resulting in lower capitation payments to the provider group. 
• As one expert put it, payers need “a full, complete picture of a member’s health”; missing lab values or vital signs means providers leave reimbursements on the table. 

In short, outdated HIEs compromise both the numerator (quality) and denominator (cost) of value-based contracts.

Regulatory penalties

The 21st Century Cures Act and its ONC/CMS regulations impwwwwwwwose strict requirements on data sharing. HIEs that cannot keep up can endanger providers’ regulatory standing. 

For example, the final information-blocking rule now empowers the HHS Office of Inspector General to fine developers and HIEs up to $1 million per violation for interfering with access or exchange of electronic health information. Providers caught in an info-blocking violation can lose their “meaningful use” status and see their Medicare payment updates reduced by up to 75%. 

In practice, this means a hospital using a laggy legacy HIE could incur penalties that directly reduce reimbursements. Modern HIE platforms are explicitly designed to meet these open-API requirements, so staying on old tech risks both fines and incentive cuts.

Operational losses translate to revenue loss

Outdated HIEs also drive up costs. When patient data aren’t readily shared, hospitals end up repeating tests and procedures instead of avoiding duplication. CHCF found that EDs with HIE access ordered far fewer imaging studies – about 9% fewer CTs and 13% fewer X-rays – compared to EDs without such access. That translated to nearly $2,000 lower cost per ED patient in some cases. 

Those savings accrue to payers under bundled payments or capitations; for providers, avoiding unneeded tests prevents wasted effort and protects profit margins. 

Likewise, reducing inpatient readmissions (for which Medicare pays nothing under its 30-day rule) directly increases net revenue. One hospital network showed that embedding HIE-driven analytics to predict CHF readmission risk led to “lower costs and higher net revenues” by avoiding penalty-prone readmissions.

Case examples

Real-world figures make the point: a Maryland Medicaid ACO reported saving $20 million in its first year of a new program once a statewide HIE enabled timely preventive outreach and care coordination. In California, a Humana-sponsored pilot found that ED visits where clinicians could access HIE data had lower costs per visit (largely through reduced testing) and shorter hospital stays. 

In New York, the state’s HIE (SHIN-NY) was estimated to create $160–$195 million per year in savings from reduced administrative waste. Projecting nationwide, full interoperability could save up to $77 billion annually. By contrast, hospitals tied to obsolete HIEs forfeit these gains – paying for extra imaging, redundant chart pulls, and slow processes that their more nimble peers avoid.

Regulatory and Compliance Risks

Beyond direct revenue loss, outdated HIEs expose hospitals to compliance dangers. Under HIPAA/HITECH, organizations must safeguard patient data with up-to-date security. Legacy HIE platforms often lack modern security patches or encryption, increasing breach risk. 

More immediately, as noted above, failing to comply with the Cures Act interoperability rules can trigger heavy penalties. Providers are expected to use certified EHRs that “provide open FHIR-based APIs” for patient access, prior authorization, quality reporting, etc. An HIE that relies on proprietary formats or closed systems may inadvertently violate the information-blocking rule. 

Starting in 2023, the Office of Inspector General can levy civil monetary penalties up to $1M on developers or HIE organizations for info-blocking. Meanwhile, CMS will publish any provider found in violation, which can lead to being treated as non-meaningful users of EHRs – a status that carries automatic Medicare payment penalties. In practice, this means hospitals should view an outdated HIE as a business risk: it could trigger audits, fines, and reduced reimbursement rates if flagged by regulators.

Modern Alternatives: API-First, Cloud-Native HIE Platforms

The good news is that HIE technology is evolving. Leading-edge HIE solutions are cloud-based, API-driven, and built on the HL7 FHIR standard, offering real-time, granular data exchange rather than batch dumps. 

For example, one industry analysis describes “cloud-native, API-driven HIE platforms” (with FHIR as the interoperability engine) that layer AI/ML analytics on top of standardized data. These modern platforms auto-scale with demand, reduce on-prem maintenance, and offer built-in security and compliance tools.

Key modern strategies include:

FHIR and SMART APIs

HL7’s FHIR has become the backbone of new interoperability efforts. As HL7 explains, FHIR “provides a means for representing and sharing information among clinicians and organizations in a standard way, regardless of how local EHRs represent the data”. 

• In practice, this means replacing bulky C-CDA or HL7 v2 documents with RESTful queries. 
• Hospitals can spin up FHIR servers or use cloud FHIR services to provide on-demand access. 
• Many state HIEs and vendor networks now offer FHIR endpoints for patient and provider queries. 
• Furthermore, collaborative initiatives like HL7’s Da Vinci project are defining FHIR-based “Implementation Guides” for payer-provider use cases. 

Adopting FHIR APIs lets hospitals meet new regulations and seamlessly integrate with payers. In fact, 70% of hospitals now support FHIR-based patient access apps, reflecting rapid adoption of these standards.

Cloud-based Infrastructure

Moving HIE data exchange into the cloud brings flexibility and cost-efficiency. Major cloud providers offer HIPAA-eligible, managed services for databases and messaging, abstracting away OS patching, backups, and disaster recovery. 

In practice, a cloud HIE can auto-scale: for example, it can instantly provision extra FHIR servers during data surges. It also gains high availability and advanced security features. Analysts note that hospitals migrating HIE to the cloud have turned a cost center into a potential revenue generator, since they can easily share cleaned, aggregated data with partners or payers.

API-first Design

Instead of treating the HIE as a passive repository, leading platforms expose APIs for every use case. This means linking real-time event feeds rather than waiting for nightly batch loads. 

Hospital IT leaders should insist on HIE products that publish open APIs for querying patient records, submitting prior authorizations, sending alerts, etc. An API-first approach also simplifies integrating new partners. Rather than building custom point-to-point interfaces for each system, a hospital can connect once to the HIE API fabric.

Modern Data Standards

Beyond FHIR, newer HIE solutions leverage standardized coding and metadata to improve data quality. For example, FHIR resources and profiles ensure that a patient’s blood pressure, medications, lab results, etc., use consistent structures and code sets. 

HIEs can also support the upcoming TEFCA framework by enabling Qualified Health Information Networks to exchange FHIR APIs under common trust agreements. Hospital CIOs should seek vendors committed to current HL7/ONC standards rather than proprietary formats – this makes future expansion much easier.

Recommendations for Hospital IT Leaders

Given these trends, what should hospitals do? Health IT executives should treat HIE capability as a strategic asset that directly affects the bottom line. Key recommendations:

Conduct an HIE performance audit

Map out all points where patient data flows and identify where delays occur. Measure time lags. Survey clinicians about which exchanges they wish they had but don’t. This gap analysis will clarify the cost of the status quo.

Engage payers as partners

Modern HIE is as much about provider-payer data exchange as provider-provider. Studies show payers are eager to contribute claims data and consume clinical data via HIE. Hospital leaders should invite major insurers into the conversation: share your EHR interfaces and ask them how they could link. Consider joining or forming collaboratives that include payers. 

For example, some HIE pilots now include bi-directional data sharing to support value-based contracts, which can accelerate risk adjustment and billing reconciliation.

Modernize incrementally but decisively

In practice, many organizations adopt a hybrid approach. For example, you might keep existing HL7 interfaces active while building a new FHIR API layer in parallel. Cloud middleware solutions can translate older formats on the fly, buying time to phase out legacy engines. 

However, don’t delay planning a full upgrade path: each year of procrastination further entrenches the cost of delay. Involve clinical leadership in defining requirements, and quantify the ROI: cite studies showing millions in savings from faster data exchange.

Ensure regulatory compliance

Any new solution must satisfy ONC/CMS rules. Verify that the HIE technology can provide open API access and comply with information-blocking exceptions. Look for platforms that are already certified or have HITRUST/EHNAC accreditation. 

If you operate a hospital that interfaces with the HIE, make sure the exchange itself has robust security audits – outdated HIE hardware might not meet current HIPAA best practices.

Invest in standards and interoperability expertise

The shift to FHIR and APIs may require new skill sets. Train your integration team on FHIR resources, SMART app development, and API security. Consider hiring a dedicated interoperability architect who understands both clinical workflows and data standards. Use industry groups and open-source tools (FHIR servers, SMART apps) to jump-start implementations.

Monitor and measure

As you modernize, track metrics: percentage of referrals using the HIE, average claim denial rate, days to receive external records, etc. Use these KPIs to justify continued investment. For example, you might find that after implementing real-time ADT feeds, readmission penalties drop or outreach program success rises.

Hospital leaders should view HIE modernization not as a back-office IT upgrade, but as a revenue assurance and compliance initiative.

By investing in modern exchange technology – cloud-native, API-first, FHIR-based – hospitals can close data gaps that currently handicap value-based payments. The result is not just better patient care, but also cleaner claims, faster payments, and stronger financial performance. In an era where “data interoperability is key to achieving care transformation,” investing in a next-generation HIE is imperative.
