What is CHIA-INET?

CHIA-INET is a Web-based transaction service of the Center for Health Information and Analysis (CHIA). The language of the actual agreement form will govern the use of CHIA-INET. This Q&A is designed to introduce CHIA-INET to potential users.


Who will use CHIA-INET?

CHIA-INET will be available to all entities (Data Reporters) that file data with the Center for Health Information and Analysis. To register for CHIA-INET, one completes and signs a Data Reporting Agreement, and has individual User Agreements completed for each individual who will be filing data for your organization. The User Agreements identify the Data Reporter's particular employees or agents/contractors and the particular submissions to which each require access. The Data Reporter is given the opportunity to restrict the access of information to its employees by submission type.


Why do I want to have my entity use CHIA-INET?

CHIA-INET will reduce administrative burden and save time and money. With Internet submissions you can:

  1. Eliminate costly media (no more tapes, disks, and paper forms) and handling.
  2. Save on courier costs to submit and track the information.
  3. Reduce the turn-around time for submissions and delivery.
  4. View your online submission logs to verify transfer status.
  5. Download submission edit reports (where applicable).


Do I need any special software programs?

If you are simply filing information that is aggregated to the organizational level (e.g., cost/financial/statistical reports), no additional software is necessary. If you are filing patient-level data, CHIA will provide you with a program that will encrypt and decrypt all files containing patient-level information. You will need Adobe Acrobat Reader version 4.0 or higher. The Acrobat Reader is available as a free download from the Adobe website. When a Data Reporter attempts to link to CHIA-INET and they do not have an upgraded browser, they will be prompted to the direct upgrade link.


What happens if I forget my CHIA-INET user name and password?

You can receive another user name and password by calling 617-701-8100 or by emailing the Help Desk at By supplying your pass phrase and security information, your request will be fulfilled. The new information will be emailed to your account.


Is there a charge to use CHIA-INET?

No. Use of CHIA-INET is free of charge.


What if I need help once I start using CHIA-INET?

You can call 617-701-8100 between the hours of 9:00 a.m. and 5:00 p.m., Monday through Friday when you need assistance. You can also send an email to


Are there any limitations to when I can enter or send my data via CHIA-INET?

The CHIA-INET system may be unavailable, due to maintenance, from 5:00 p.m. to 8:00 a.m. on Monday through Friday.


How long will CHIA-INET remain open if I do not hit a key?

There is a 25-minute time-out when on online. If a user does not press a key for 25 minutes, he/she will be logged out and placed back at the sign-on screen. This means that any data being entered online that has not been saved will be LOST. Therefore, users should get the information ready before logging on, and be sure to SAVE information before going off or looking for information. Users can save data and reenter the online data screens many times until the data is actually submitted, so users should save data frequently during any session.


Do I need to formally register for CHIA-INET ?

Yes, you must register for CHIA’s web-based transaction service. To register for CHIA-INET, each individual user filing for an organization must complete and sign a Business Partner Security Agreement Form, and complete a User Agreement for Insurance Carriers. Completed forms may be submitted to
