We’re an experienced, not-for-profit leader in Medicaid and committed to providing high quality health coverage to underserved populations. We’re making it easier for providers like you to work with us.

See if a Prior Authorization is Required

Before scheduling a service or procedure, determine whether or not it requires prior authorization.

  1. Search prior authorization requirements by using one of our lookup tools:
  2. If approval is required, review the medical and payment policies
  3. Reference your patient’s covered services list to understand what’s covered by their plan
  4. Download and submit the prior authorization form:


If your prior authorization request is denied, you may request an appeal. Pharmacy appeals must be submitted within 30 calendar days from the date of the denial notification. Send your appeal, along with any additional information, to us by mail at:

More Claims Information

For earlier submissions and faster payments, claims should be submitted through our online portal or register with Trizetto Payer Solutions here. Or use the following clearinghouses:

  • Gateway EDI
  • NEHEN (New England Healthcare EDI Network)

You must correct claims that were filed with incorrect information, even if we paid the claim.

The most common reasons for rejected claims are:

  • The NPI is incorrect, not listed on the claim, or does not match the tax identification number in our system.
  • The member ID number is invalid.
  • The original claim number is not included (on a corrected, replacement, or void claim).

Please be aware that:

  • If we reject a claim for a missing NPI number, you must submit it as a new claim with updated information.
  • If we request additional information, you should resubmit the claim with the additional documentation. Do not submit it as a corrected claim.

Electronic Claims

The process for correcting an electronic claim depends on what needs to be corrected:

  • To correct the provider name, NPI number, member name, or member ID number, you must first process a void claim, and then file a new claim.
  • To correct billing errors, such as a procedure code or date of service, file a replacement claim.

Replacement and void claims must include the original claim number in a specific position in the 837: Loop 2300, Segment REF - Original Reference Number (ICN/CDN), with “F8 ” in position 01 (Reference Identification Qualifier) and the original claim number in position 02.

For more information on electronic placement and void requests, please see the EDI Claims Companion guide for 5010, or contact your Provider Relations representative.

Paper Claims

To submit a corrected paper claim:

  • Print out a new claim with corrected information.
  • Write "Corrected Claim" and the original claim number at the top of the claim.
  • Circle all corrected claim information. Please do not hand-write in a new diagnosis, procedure code, modifier, etc.
  • Include the Plan claim number, which can be found on the remittance advice.
  • Submit the claim in the time frame specified by the terms of your contract to:

    BMC HealthNet Plan
    P.O. Box 55282
    Boston, MA 02205

Submit a Claims Appeal

If you don't agree with how a claim was processed, you can request a claim review using the Universal Request for Claim Review Form. Complete the entire form and submit the appeal and supporting documentation within your contracted timely filing limit to the address below.

This is considered a first level appeal. If your appeal is denied, it is considered an administrative denial, and you may submit a second level appeal (second administrative appeal), as described below.

Second Level Appeal

If your initial claim review results in an administrative denial, you may file a second administrative appeal. An Administrative Appeals Review committee automatically reviews all second level appeals and their decisions are final.

To appeal, send a copy of the denial letter along with supporting documentation for the denied claim that specifically outlines the reason for a second level appeal to the address below.

Second Level Appeal Procedures:

  • If we receive your request for a second level appeal after your contracted timely filing limit, the Plan upholds the original denial.
  • If we receive the appeal within the filing limit, it will be reviewed by the Administrative Appeals Review committee, which will provide a final decision on the claim.
  • The Administrative Appeals Review committee makes a determination within 30 days following receipt of the appeal accompanied by the appropriate documentation.
  • After the appeal has been reviewed, a resolution letter describing the decision is mailed to the provider.

Mail appeals and supporting documents to:
