Becoming a DIA EDI partner

Discover the information you need to know and steps you need to take to become an EDI partner with the DIA.

Information you need to know

  • There are a series of steps involved in becoming a trading partner:
  1. Begin by reviewing the web pages found on this web site
  2. Review the IAIABC EDI Implementation Guide at www.iaiabc.org
  3. Contact the Massachusetts Department of Industrial Accidents to be setup as a trading partner
  4. Complete a testing phase with the department
  5. Prepare for production implementation
  • Massachusetts Department of Industrial Accidents (DIA) currently supports the IAIABC Release 3 standard only.
  • The DIA currently accepts only the First Report of Injury (FROI) transactions using the IAIABC Release 3 standard.
  • The DIA currently doesn't accept any Subsequent Report of Injury (SROI) transactions; however, these transactions may be accepted and supported in the future based upon the IAIABC Release 3 standards.
  • The IAIABC Release 3 standards only allow for the flat-file format of the transactions and that's the only format we accept.
  • The DIA currently only supports the EDI 148 and its companion R21 record types. Within these transactions the only maintenance type codes (MTCs) that are supported are:
    • 00 - Initial Claim
    • 01 - Cancel
    • 02 - Change
  • Trading partners are expected to send EDI transmissions as batches of transactions. Each batch requires a header record as the 1st record in the batch, followed by at least 1 or more First Report of Injury (FROI) transactions and a trailer record as the last record in the batch. EDI batches that don't follow these standards will be rejected.
  • Multiple batches can be sent in a single EDI transmission file when trading partners are using the Release 3 standard. Acknowledgments for each batch will also be returned to the trading partner in a single acknowledgment transmission file when multiple batches are processed.
  • The MTC codes that are supported for the FROI transaction are:
    • 00 - Initial (new) claim
    • 01 - Cancel claim
    • 03 - Update claim
  • The DIA accepts EDI transmissions through a direct connection to the department's EDI FTP server only. Only secure FTP transmissions are allowed.
  • An acknowledgment transaction (AKC) is generated for each FROI transaction that is received. The acknowledgment file will contain a header transaction (HD1) as the 1st record and a trailer transaction (TR2) as the last record in the file.
  • We require the acceptance and processing of acknowledgment files to obtain data quality standards. It's expected the trading partner will send update (MTC 02) transactions to correct any errors identified in the originally transmitted transaction. In the case of rejected transactions (TR), the trading partner must send the original transaction (MTC 00) with corrected information.
  • The frequency of transmitting EDI data is generally dictated by the statutory reporting requirements. Each trading partner can schedule its EDI data files to be transmitted daily, multiple times during the day, or at less frequent intervals throughout the week as necessary. The department currently processes EDI transmissions in real-time.
  • Massachusetts requires that the jurisdiction (agency) claim number is returned in the acknowledgment file for each successful new FROI transaction processed. The assigned jurisdiction claim numbers need to be supplied for additional processing of updates or cancellations.
  • A Form 101 - First Report of Injury needs to be filed with Massachusetts for all claims where there is claimed lost time beyond the waiting period, which is five full or partial calendar days, or where indemnity benefits have been paid, whichever comes first. NOTE: The DIA doesn't accept medical-only claims or claims that result in less than 5 full or partial days of disability.
  • Each transaction must contain both a 148 and a R21 record. They are a matched pair and the transaction will be rejected if one or the other is missing.
  • Fields can't be left blank on either the MTC 01 (cancel) or the MTC 02 (change) transactions. The same validation rules apply regardless of the MTC code.
