Claims Status

The claim status inquiry functionality in the Provider Online Service Center allows you to verify the status of a claim submitted to MassHealth. After MassHealth processes a claim, the claim is given a 13-digit Internal Control Number (ICN). Providers can upload a 276 batch file and download the 277 response (HIPAA transaction sets) for the status of the claim through the Provider Online Service Center or through direct data entry (DDE) claims status panels.

The status is also available on the MassHealth issued remittance advice (RA).

Claim Denials and Suspensions


Claims (both batch and DDE) that deny contain edit code(s) that describe the denial reason. These claims must be reviewed, corrected (if applicable), and resubmitted to MassHealth within the appropriate time frame. To visit the list of edits that can appear on the RA, please see the List of Explanation of Benefit Codes appearing on the Remittance Advice and other additional aids listed in the Additional Claims Resources section below.


A suspended claim is a claim that requires review before final adjudication. When a claim appears as suspended on a remittance advice (RA), the ICN assigned to the claim will remain the same throughout the processing cycle. You should post the claim as received by MassHealth. Do not rebill the claim while it is in suspense. The suspended claim will appear on a subsequent RA as paid or denied.

Remittance Advice (Claim Status Reporting)

A Remittance Advice (RA) is a report that provides claims processing status to providers indicating if the claim is paid, denied, or suspended (please see additional information below regarding denied and suspended claims). The RA is a helpful tool when reconciling accounts, as it reports the status of a claim submitted to MassHealth.

The RA is available in two forms: the 835 electronic RA, and the downloadable PDF RA, which is available online. The 835 (HIPAA transaction) RA can be downloaded from the POSC by a provider who has a signed Trading Partner Agreement (TPA) on file with MassHealth. The RA in PDF format also displays information about claim status, although it appears in a format that is unique to MassHealth. Providers can review, download, or print the PDF RA on the Provider Online Service Center.

Each Tuesday, the applicable RA is given a 6-digit run number, e.g., 100139, one week and 100140 the next week. On a weekly basis, the Remittance Advice is posted on POSC for providers.
