Provider Benefits
GVHN offers a variety of benefits to physicians in south and central Texas, including:
Managed Care Contracting Services via Messengering Model
GVHN facilitates group contracts with managed care payers and networks on behalf of its provider members.
As required by the Federal Trade Commission, GVHN must use the messenger model
system of disseminating fee proposals, as it is a non-integrated group of facilities and physicians.
Delegated Credentialing through Managed Care Plans
GVHN has a quality physician credentialing program and has been
successful at obtaining delegated credentialing through all of its managed care contracted payers. GVHN follows the
National Committee for Quality Assurance and State of Texas guidelines for physician credentialing.
Discounts on Malpractice Insurance via Texas Medical Liability Trust
GVHN physicians who have TMLT insurance receive additional savings just by being members of our provider network.
While TMLT has discontinued its discount program with most provider groups, GVHN has been to retain this benefit
due to the low loss ratio of its TMLT participating physicians.
Access to Continuing Education Programs
GVHN provides free continuing education programs for its providers.
Two TMLT sponsored programs are provided each year, allowing physicians to receive additional TMLT savings,
and ethics and CME credit. Other educational programs are provided to physicians and their office staff as
needed or requested. Monthly office manager meetings are also available to inform physician managers of changes in GVHN and the local managed care market.
Marketing and Physician Advocacy Services
GVHN markets the services of its providers through this website, a physician referral service and special
announcements as needed. GVHN also assists providers with various issues such as non-routine claims payment.
For a complete list of provider benefits, download the GVHN Provider Benefits PDF.
Facility Benefits
GVHN facilitates managed care contracting services for its facility providers. These providers currently include
Guadalupe Regional Medical Center, Otto Kaiser Memorial Hospital,
and South Texas Surgical Center. For information about how GVHN may accommodate your facility, call (830) 303-4846.
