Healthpac and inMediata partnering to conduct case study to assess adoption of ERAs and EFTs in medical billing

August 31, 2015

Case study intended to encourage the acceptance of ERAs and EFTs as safe and convenient alternative to paper reports.

SAVANNAH (August 31, 2015) – Medical billing software provider Healthpac Computer Systems, Inc., and healthcare payments company inMediata have announced a plan to collaborate on a case study to assess the usage of Electronic Remittance Advice (ERA) and Electronic Funds Transfer (EFT) in medical billing.

The case study will include full electronic confirmation and reconciliation of bank transfers from the banking institutions without the extra requirement of manual intervention and is intended to fully evaluate the life cycle from claims to payments to ERAs and ultimately the electronic confirmation frommedical-billing-software the banking institutions that an EFT has taken place. The objective of the study is to validate the elimination of the need for a user to manually release ERAs after a manual confirmation of the EFT transmission.

As part of the case study, Healthpac will be receiving from InMediata both the ERAs (Electronic Remittance Advices) and electronic confirmation files from the banking institutions that the EFTs (Electronic Funds Transfer) have been automatically processed into the client’s bank accounts. This process will provide complete reconciliation that can be done virtually without any user intervention. The results of the case study should encourage more widespread usage and acceptance of fully automated transmission of EFTs and ultimately lead to greater cost savings and operational efficiencies.

“InMediata is an ideal partner for this case study, because they offer an array of special processes and services that compliment the ERA/EFT process in Healthpac’s software that does the actual payment Buddy Clabornprocessing of the remittance files when mutually integrated,” said Healthpac CEO Buddy Claborn. “We believe conducting this case study collaboratively will clearly reveal the efficiency that can be gained through the utilization of the ERA/EFT process, and we look forward to sharing our results with the entire medical billing industry once the case study is complete.”

Healthpac clients use the HPlusPRO software system to create an ANSI 837 file for transmission to a carrier/clearinghouse, and this file is an approved electronic format for submitting charges to insurance carriers. inMediata, which works with more than 10,000 providers in all 50 US states and Puerto Rico, offers products used to transfer the required paper documents to electronic media, and the two companies will work together to monitor each step the client took to make full automatic reconciliation of an ERA through EFT.

By closely monitoring transactions for an estimated two months, Healthpac and inMediata will be able to detail the process of becoming fully ERA and EFT compliant. Once the study is complete and data has been compiled, the two companies plan to share the findings of the joint case study through a future webinars sponsored by the American Medical Association and the Medical Group Management Association.
