Patient Misidentification: A Costly Challenge for Healthcare—Can the MATCH IT Act Help?
The Growing Problem of Patient Misidentification
Patient misidentification poses serious risks to interoperability, patient safety, and privacy. Without widely adopted industry standards for patient matching, errors and duplicate records persist, leading to medical mistakes, denied claims, and increased costs.
The Financial and Clinical Toll
Research highlights the staggering financial impact of patient misidentification:
- 1 in 3 claim denials stem from inaccurate patient matching. (Black Book Research)
- Hospitals lose an average of 2.5million annually.
- 24% of patient records contain duplicates, costing:
- $1,950 per inpatient stay
- $1,700+ per emergency department visit
Beyond financial losses, misidentification leads to:
- Medical errors (wrong treatments, misfiled test results)
- Privacy breaches
- Interoperability gaps—45% of large hospitals report challenges exchanging health data due to mismatched records. (GAO, 2019)
Legislative Action: The MATCH IT Act
To address these issues, U.S. Representatives Mike Kelly (R-Pa.) and Bill Foster (D-Ill.) reintroduced the Patient Matching and Transparency in Certified Health IT (MATCH IT) Act in March 2025 (originally proposed in February 2024).
Key Goals of the MATCH IT Act
- Standardize Patient Matching Metrics
- Establishes an industry-wide “patient match rate” definition to track improvements.
- Accounts for duplicate records, multiple matches, and mismatches within provider systems.
- Enhance Data Interoperability
- Requires the ONC (Office of the National Coordinator for Health IT) to:
- Define a minimum data set for patient matching within 180 days of enactment.
- Ensure 99.9% accuracy in matching across systems.
- Consult healthcare stakeholders to refine standards.
- Requires the ONC (Office of the National Coordinator for Health IT) to:
- Balance Privacy & Efficiency
- Avoids a national unique patient identifier (previously blocked due to HIPAA privacy concerns).
- Instead, optimizes existing data infrastructure without overburdening providers.
Industry Support
The Patient ID Now coalition—including AHIMA, HIMSS, CHIME, and Intermountain Health—endorses the MATCH IT Act, calling it a critical step toward:
✔ Reducing misidentification errors
✔ Improving patient privacy
✔ Strengthening interoperability
The Road Ahead
If passed, the MATCH IT Act could transform patient matching by:
✅ Setting clear standards for health IT systems
✅ Reducing costly errors and claim denials
✅ Enhancing patient safety and data exchange
As healthcare embraces AI and digital transformation, standardized patient identification is more crucial than ever. Will this legislation be the solution the industry needs?
Key Takeaway: Patient misidentification is a billion-dollar problem—but with structured policies like the MATCH IT Act, healthcare may finally see better accuracy, safety, and cost savings.
