Why Interoperability is Important for the Health Care Industry

Interoperability is so important in healthcare because it’s the foundation for making the system work as one connected ecosystem instead of a patchwork of isolated silos. Here’s why it matters:
- Better Care for Patients
-
- Patients move between primary care doctors, specialists, hospitals, labs, pharmacies, and insurers.
- If systems can’t share information, critical details (medications, allergies, test results) get lost, leading to duplicated tests, delays, or even harmful errors.
- Interoperability ensures providers have the full picture of a patient’s history and current treatment, improving safety and outcomes.
- Reduced Administrative Burden
-
- Today, a huge amount of time and money is wasted on manual processes—faxing, phone calls, portals, re-entering data.
- When data flows automatically between payers, providers, and regulators, it reduces overhead, accelerates prior authorization, eligibility checks, and claims, and lowers costs for both patients and the system overall.
- Regulatory Compliance and National Alignment
-
- Rules like CMS’s Interoperability and Prior Authorization Final Rule (CMS-0057-F) and ONC’s 21st Century Cures Act APIs mandate that patients and providers can access and exchange data via standard APIs (FHIR, X12, etc.).
- Without interoperability, health organizations risk falling behind on compliance, penalties, or exclusion from national networks like TEFCA.
- Equity and Access
-
- Interoperability levels the playing field for smaller practices, community health centers, and post-acute providers who otherwise lack resources to connect with large systems.
- By standardizing data exchange, patients in under-resourced settings get the same access to coordinated care as those in major academic medical centers.
- Innovation and Value-Based Care
-
- Health plans and providers are shifting toward value-based models where reimbursement depends on outcomes, not just volume.
- This requires shared data on quality measures, social determinants of health, and real-time utilization.
- Interoperability makes it possible to bring in AI, digital health tools, remote monitoring, and patient apps that all plug into the same ecosystem.
- System-Wide Resilience
-
- Public health crises (like COVID-19) exposed the dangers of fragmented systems: states, hospitals, and labs couldn’t easily share real-time case or capacity data.
- Interoperable infrastructure strengthens preparedness for pandemics, disasters, and cybersecurity resilience.
