Q: What is the Provider Online Service Center (POSC)?
A: The POSC is a web-based portal that is available to MassHealth providers, business partners, and relationship entities to view information, submit and receive transactions, and effectively conduct business with MassHealth online. Providers, business partners, and relationship entities must be enrolled in and/or registered to use the POSC.
Q: What type of services are available on the POSC?
A: Users may perform a wide variety of functions that will enable them to submit claims, authorization, and eligibility requests, as well as view notices, query report data, and access a host of other services. Please see the appropriate section below to view the available services.
Q: How can providers, business partners, and relationship entities register to use the POSC?
A: Providers, business partners, and relationship entities may register to use the POSC during the MassHealth application process. You will be asked to supply registration information at the time of enrollment. Your user ID and password will appear on the screen and a confirmation e-mail with registration instructions will be sent to the e-mail address you provide. While this user ID and password will enable you to complete your application, full access to the POSC will be given only after you have been approved for participation in MassHealth.
If you elect to submit a paper application, you will receive a user ID and password to access the POSC after you have been approved for participation in MassHealth.
Q: While entering information on the POSC, do I need to complete fields that are not marked with a red asterisk (*)?
A: The absence of an asterisk does not indicate that a field is optional. Only certain fields that are consistently required in any given transaction are annotated with an asterisk. The remaining fields are conditionally required, depending on the transaction or the applicable function.
Q: I do not seem to have access to the POSC. What should I do?
A: Please contact the Primary User (account administrator) within your organization. If your organization has not registered, please identify a Primary User. The Primary User will be the person in your organization who will be responsible for the creation and inactivation of users’ accounts and password resets.
The Primary User or office administrator must complete the Data Collection Form to obtain a user ID and password for the Primary User to access the POSC and Automated Voice Response (AVR). If you have previously registered for POSC access but do not have your username and password, please contact the Virtual Gateway Help Desk at 1-800-421-0938. For questions on the Data Collection Form, contact the MassHealth Customer Service Center at 1-800-841-2900 (TTY: 1-800-497-4648 for persons who are deaf, hard of hearing, or speech disabled).
Q: Where can I view up-to-date information issued by MassHealth about the POSC?
A: MassHealth issues standard broadcast messages to users via the POSC. Users can view these messages by logging into the POSC at www.mass.gov/masshealth/providerservicecenter, clicking on Manage Correspondence and Reporting, and then on View Broadcast Messages. MassHealth encourages viewing messages daily for timely updates.

To upload or download HIPAA transactions, access any of the batch-upload processes available under Manage Service Authorizations, Manage Members, or Manage Claims and Payment.
Q: Will anyone else have access to my organization’s data on the POSC?
A: Other POSC users will not be able to view your information unless your systems administrator (Primary User) gives him or her access to your information by selecting the Administer Account function on the POSC.
Q: How secure is my information on the POSC site?
A: The Commonwealth of Massachusetts recognizes the importance of protecting the information entrusted to us. To ensure that the information is protected, we have followed industry-standard security procedures and implemented a solution that protects the data in all stages. While the data is in transit between your browser and our servers, we use 128-bit Secure Socket Layer (SSL) security. After the transmission to our systems, the data is protected by multiple layers of firewalls. The data is stored on secure, “hardened” servers that allow access only to a minimum set of authorized users. Additionally, the HIPAA privacy guidelines are followed while data is accessed.
Q: Is any online help available on the POSC?
A: Online field level help is available on every panel within the POSC. Simply hover over a field and the “help” information will appear on the screen.
Q: Where can I find information about scheduled system maintenance and other information about POSC access?
A: MassHealth posts information about scheduled system maintenance and other important information in the “Manage Correspondence and Reporting” section of the POSC. Additionally, announcements and updates are posted on the MMIS web page. You can access any MMIS-related announcements directly at www.mass.gov/masshealth/newmmisnotices.
Providers should make every effort to take advantage of these resources to stay informed. If neither of these suggestions works, please contact the Virtual Gateway Help Desk at 1-800-421-0938.

Q: I am the Primary User for my organization and cannot locate my login information. What should I do?
A: Some providers have found this information routed to their spam or junk e-mail folder. Check alternative sources to see if this information was inadvertently misrouted to such a folder. If you still cannot locate the user ID and password information, contact the MassHealth Customer Service Center at 1-800-841-2900.
Q: What happens if an organization's Primary User leaves?
A: MassHealth should be notified of any event, such as the termination of its relationship with a previously authorized Primary User. Please identify a new Primary User for your organization by completing a Data Collection Form . If you have questions, contact the MassHealth Customer Service Center at 1-800-841-2900.
Q: What happens if a Primary User creates a subordinate ID for one of his or her staff and someone else tries to establish an ID for that same person?
A: The system will not allow the creation of a second ID with the same attributes. If you are still experiencing duplication errors, contact the MassHealth Customer Service Center at email@example.com or call 1-800-841-2900.
Q: I am having trouble creating a subordinate ID for POSC access. Where can I go for help?

A: Please contact the Primary User within your organization. Your Primary User should confirm that you are set up with the appropriate subordinate user privileges that allow you to submit and/or access certain information via the POSC. If you are the Primary User and experiencing issues accessing the POSC, contact the MassHealth Customer Service Center at 1-800-841-2900.
Q: How can I remove access for a user who no longer requires access to a specific provider?
A: Only the Primary User and backup Primary User can deactivate POSC access for a user. The Primary User or backup Primary User must contact the MassHealth Customer Service Center at firstname.lastname@example.org or call 1-800-841-2900. The representative will ask for the following information: primary/subordinate user ID, name (first and last), e-mail address, and reason for change. The representative will use this information to update system data.
Q: Does the POSC allow users to upload and download HIPAA batch transactions?
A: Yes. Users may submit batch transactions and receive batch responses that are supported by MassHealth via the batch-upload process. Please access anyone of the batch-upload processes available under Manage Service Authorizations, Manage Members, or Manage Claims and Payment.

The “Manage Service Authorizations” function allows the user to manage Prior Authorization (PA), Preadmission Screening (PAS), and Referrals. Users can enter requests, inquire about requests, and modify requests under certain circumstances.
Preadmission Screening (PAS)
Q: What is a PAS request and how do I use it?
A: Preadmission screening (PAS) is the MassHealth authorization process for elective, acute inpatient hospital admissions, or rehabilitation services provided in an acute inpatient hospital, or chronic hospital stays for MassHealth members who require these services. MassHealth providers are required to obtain permission from MassHealth prior to the elective admission.
The screenings determine if the admission is medically necessary and if the inpatient setting is appropriate.
For additional information about preadmission screening requirements, see MassHealth regulations at 130 CMR 450.207 through 450.209 for acute admissions and 130 CMR 435.408 through 435.415 for rehabilitation services provided in an acute inpatient hospital and chronic or rehabilitation admissions and extensions.
Q: How do I submit a PAS request?
A: Providers can submit their PAS request through the POSC as a single transaction using direct data entry (DDE).
Q: What type of PAS requests can providers submit online?
A: Providers can submit the following types of PAS requests online.
- New admission for elective inpatient hospital stays in acute, chronic, or acute with rehabilitation facilities
- Concurrent review (extensions) for chronic or rehabilitation stays and acute stays with rehabilitation services
- Conversion from other insurance for chronic or rehabilitation stays and acute stays with rehabilitation services
Q: What provider information do I need to submit a PAS request?
A: The facility and attending physician provider ID and service location must be on the PAS request, as well as the provider contact name, phone, and fax numbers. All required fields must be filled in or the PAS request will not be processed.
Q: How do I send in documentation to support an elective inpatient submission?
A: Supporting documentation is easily uploaded using the online POSC. Printed documentation may be scanned and then added/uploaded as an attachment. Another option is to make a copy of printed documentation using an up-to-date copier, e-mail the copied information to a secure email and attach the newly created electronic image as instructed above. Please refer to the Create a PAS Request file size 1MB file size 1MB job aid for more information. Supporting documents must be submitted to substantiate the reason for the elective inpatient admission.
Q: May I use a CPT (Current Procedural Terminology) code when submitting a PAS request?
A: No. ICD (International Classification of Diseases) codes are required for all PAS requests. No other code set will be accepted on a PAS request.
Q: How long will it take Permedion to respond to PAS requests entered through MMIS? Are there any specific guidelines for shortening response time?
A: The turnaround time depends upon how much lead-time providers give Permedion when they submit their requests. The regulations at 130 CMR 450.208(A) state that providers must give seven days' lead-time, but in the majority of cases they do not. Permedion prioritizes submitted requests daily. Last-minute requests may affect Permedion's processing time. Please remember to submit PAS requests seven days prior to admission to prevent system delays. Please use the online POSC as the turnaround time is faster. Please refer to the Create a PAS Request file size 1MB file size 1MB job aid for instructions to request a PAS online.
Q: How do I use the Prior Authorization (PA) Service?
A: Providers may use the Prior Authorization (PA) service to obtain approval prior to providing certain services to MassHealth members. This service enables MassHealth to review, assess, approve, modify, or deny selected nonemergency medical services prior to payment.
For regulatory information about prior authorizations, see MassHealth regulations at 130 CMR 450.303 and other applicable program regulations.
Q: How do I submit a PA request?
A: Providers may submit PA requests via the POSC using direct data entry (DDE).
Q: What type of PA requests and functions can providers perform online?
A: Providers can perform the following requests and functions online using the POSC.
- Submit requests for medical services and products
- Check the status of a request
- Receive PA notices communicating decision information
Q: The drop-down field for selecting a transmission code within in the PA entry panels on the POSC lists several options. How do I know which one to use to submit my PA requests?
A: Providers submitting electronic PA requests must select the "electronically only" option. Do not select any other option from this field. The choices for sending a PA request and its associated attachments are electronically—submitting the PA request electronically with electronic versions of the attachments—or on paper —submitting the paper PA-1 form along with any necessary paper attachments.
Q: What is the Control Number field located under the Attachment tab in the PA entry application in MMIS? Am I required to complete it?
A: The control number is a system-assigned key and is unique for each attachment. Its purpose is to link the attachment to the PA request. As such, a user cannot populate it; the number is assigned by the system.
Q: What is the number to fax PA requests and PA attachments to MassHealth?
A: Providers who have scanning capability should submit their PA requests and attachments electronically via the POSC. Providers who do not have scanning capability should contact the MassHealth Customer Service Center at 1-800-841-2900 to inquire about an eFax account. EFax works like an ancillary scanner, preparing documents for electronic submission. Only a limited number of eFax accounts can be established though. If you already have electronic scanning capability, MassHealth encourages you to use it. Providers having trouble with their eFax transmissions should contact the MassHealth Customer Service Center at 1-800-841-2900.

Q: How do I submit claims to MassHealth?
A: This service is used to submit claims to MassHealth. Claims may be submitted online individually using direct data entry (DDE) or a batch process via MassHealth’s connectivity method using SOAP + WSDL, as well as HTTP MIME submission methods.
Direct Data Entry (DDE). Use this service to submit electronic claims to MassHealth individually. Providers do not need to submit test files in order to submit claims via DDE. Providers may log into the POSC and begin submitting claims via DDE 24 hours a day, seven days a week, and receive immediate results on the status of the claim: Paid, Denied, or Suspended.
Batch Processing. Use this service to submit electronic, HIPAA-compliant claims to MassHealth in batches. Providers must successfully submit a test file and be approved to submit production claims before they may submit files for batch processing through the POSC or system-to-system.
MassHealth advises providers about the need to update their submitter field with the appropriate MassHealth ID as a preparation step for submitting 837 transactions in MMIS.
Confirm that 837 files are sent as production files, with a "P" entered into the ISA15 field. Files submitted with a "T" are processed as test files only. If all of the above information has been confirmed, the 837 file may have failed precompliance. Mistakes in completing the ISA06 field of the 837 file are among the most common submitter mistakes to cause a pre-compliance failure. The ISA06 is a fixed field. The submitter must enter exactly 15 characters and spaces into the field. Providers must enter their 10-digit provider ID/service location number followed by five spaces.
Please note that the MassHealth EDI team is tracking the submission of 837 files and, for a time, is contacting those providers with files that have failed precompliance to assist in correcting the issue further. For more information about the ISA06, ISA, and GS02 fields, refer to the HIPAA Implementation Guide.
Inquire Claim Status. Use this service to check the status of claims submitted via batch, DDE, or paper.

Q: Will I receive confirmation once I submit my claims?
A: If you submit your claims using DDE, you will receive a response indicating the status of the claim immediately after submission.
If you submit your claims using system-to-system processing (HIPAA-compliant files), a confirmation screen panel will provide you with a tracking number for your submission. After your claims are processed, a HIPAA-compliant acknowledgement (TA1 and/or 999) will be posted on the POSC under your account.
Q: Can I check the status of my claims?
A: If you submit your claims using DDE, you can check the status of a claim by clicking on the Inquire Claims Status link in POSC. In addition, when you submit your claims via DDE, you will receive an immediate response indicating the status of the claims.
If you submit your claims using batch processing, you may submit a 276 request to check the status. This action will generate a 277 response.
Q: Why do my claims keep getting denied?
A: Refer to your weekly remittance advice to identify the denial reasons file size 2MB.
Please ensure that you are billing in accordance with the current billing instructions.

Business Partner Enrollment
Q: How can I manage my information on the POSC?
A: MassHealth works closely with a variety of entities that support our provider and member communities. Business partners may enroll and maintain their profile via the POSC. Below are examples of the types of business partners who may enroll via the POSC.
- Billing intermediaries and/or clearinghouses – This type of business partner submits electronic claims for their clients who are providers. They need to be enrolled in the POSC in order to submit electronic claims for their clients.
- Health-care advocacy groups – These are groups that represent providers or members
- Provider associations – These associations represent various provider types (i.e., physicians and hospitals, nursing facilities, etc.)

Q: I am a current MassHealth provider. How can I update my information online?
