For years, the health care industry has struggled to maintain accurate and consistent provider data as a result of physicians moving locations, joining new networks and adjusting care offerings. Learn how blockchain technology can be used to support a new kind of master data management system for provider data.

Adoption of digitization in health care is slow.
Adoption of digitization in health care historically has been slow due to the industry’s
resistance to change.
Digitization in health
care lags behind 10 other
industries with an index
value of 1.7, compared
with the leading industry
cluster (IT) at 2.9.

Provider data management

10. Page 9 EY Global Blockchain Summit
Provider data management
Provider data is the
information about a
provider (i.e., physician)
contained in a provider
directory, referenced
during the claims process
and used to determine
network adequacy.
Payors maintain
their own “source
of truth” systems
internally.
Updates come
from a variety of
sources, including
the providers.
CAQH* acts as an
industry
clearinghouse for
provider data.

Identity validation

14. Page 13 EY Global Blockchain Summit
New member onboarding
Health plans validate new
members by passing
basic identity information
(name, address, date of
birth, etc.) to third-party
identity verification
services like Equifax,
Lexis Nexis, Experian,
IDology and others.
The health plan is charged each
time they submit a verification
request to a service provider. The
cost per request can be close to
$1.00.

Smart contracts can

which information is
considered “valid.”

Electronic medical records

17. Page 16 EY Global Blockchain Summit
New member onboarding
Medical records are
naturally “episodic,”
meaning they relate to a
specific episode or
occurrence of care.
Longitudinal records
(across providers and
health plans) do not exist
unless the patient is
diligent about maintaining
a personal file.
Electronic medical records (EMR) and
electronic health records (EHR) exist,
but there are hundreds of vendors and
platforms, and interoperability is a
challenge.

Decentralized health information exchange
Episodes of care are
memorialized on the
blockchain, recorded as a
pointer to the actual EHR
kept by the provider.
Provider access to a file
pathway is granted only
after patient authorization
is provided via a private
key signature.
The blockchain serves as a
mapping and permission
system for the patient’s
medical records.
