The MATCH IT Act is back, now sold as a prerequisite for healthcare AI

On Aug. 5, Sens. Mark Warner (D-VA) and Jim Banks (R-IN) introduced the MATCH IT Act of 2026, legislation that would direct HHS to set national standards for measuring how often patients are correctly matched to their medical records.

“Patient matching errors are a hidden tax on the healthcare system,” Banks said in a statement. “This bipartisan bill would make sure doctors have the right patient’s records and reduce medical errors, speed up care, and reduce healthcare costs.”

Patient matching legislation has a rough history in Congress. The broader fix, a national patient identifier, has been blocked by a funding ban since 1999, and the 2024 version of this bill died without a vote. The new Senate bill is a companion to H.R. 2002, identical legislation that Reps. Mike Kelly (R-PA) and Bill Foster (D-IL) introduced in the House in March 2025.

The bill’s provisions have changed little since 2024. It still centers on standardized measurement of match rates and uniform demographic data in certified health IT. What has changed is the pitch. Sponsors and industry backers now argue that patient matching is a prerequisite for AI in healthcare.

“AI has the potential to transform healthcare, but its effectiveness depends on accurate, trusted patient data. As providers manage a historic volume of health information, the need for a national patient matching standard has never been more urgent,” said Russ Branzell, CEO of the College of Healthcare Information Management Executives (CHIME). Branzell added that the bill would lay “the foundation for safe and effective AI adoption” by reducing duplicate records and manual reconciliation.

What the MATCH IT Act would require

Under the MATCH IT Act, HHS would establish a uniform definition and standards for patient matching, so the industry can track match rates, duplicate records and multiple matches, and document improvement over time. It directs ONC to define a minimum set of demographic data elements that certified health IT products must adopt, with the goal of supporting a 99.9 percent match rate.

CMS would create a voluntary bonus measure within the Medicare Promoting Interoperability Program, paying an adjustment to providers who reach a 90 percent match rate. A separate voluntary program would let providers anonymously report matching data to HHS.

Why the bill avoids a national patient identifier

The bill does not create a unique patient identifier, the fix HIPAA mandated in 1996. In 1998, then-Rep. Ron Paul (R-TX) introduced language blocking federal funds for the identifier’s development, citing privacy concerns. The prohibition took effect in the 1999 appropriations bill, and Congress has carried it forward nearly every year since. When appropriators briefly dropped the language in 2021, Sen. Rand Paul (R-KY) led the opposition, and the ban returned.

Kelly and Foster previously lled two successful House votes to lift the ban, but the measure never cleared the Senate. The MATCH IT Act instead standardizes measurement and demographic data capture without touching the identifier.

What patient matching errors cost

Supporters cite figures from Black Book Research, which puts the cost of care tied to duplicate records at $1,950 per inpatient stay. The firm attributes 35 percent of denied claims to inaccurate patient identification, at a cost of $2.5 million for the average hospital and more than $6.7 billion annually for the US healthcare system. The figures are survey-based estimates from 2021.

The the Healthcare Financial Management Association’s (HFMA) analysis suggests the standardized demographic elements could push match rates into the high 90s, pulling denial rates down with them.

Who supports the MATCH IT Act and where it stands

The Patient ID Now coalition, whose founding members include AHIMA, CHIME, HIMSS, and Intermountain Health, is driving support. Endorsers range from the American College of Physicians and the American Heart Association to health systems including Parkland Health and Nemours Children’s Health, along with identity vendors such as Verato and Imprivata.

If the voluntary bonus measure becomes law, providers who already measure and document their match rates would be positioned to collect first.
