The NHP forms and applications providers use most:

Prior Authorization Forms

Other Provider Forms

Credentialing and Enrollment Forms

Neighborhood Health Plan, in conjunction with the Massachusetts Association of Health Plans, the Massachusetts Medical Society and the Massachusetts Hospital Association, has developed the HCAS Provider Enrollment Form—a single, uniform application that facilitates the credentialing process for all physicians practicing in the Commonwealth.

You can visit the Healthcare Administrative Solutions resource page for more information.

Providers are encouraged to download it, fill it out, and fax or email it to our Provider Service Center. If you have any questions, please contact NHP’s Provider Service Center:

Standardized Provider Information Change Form

To make sure that health plans and their members have the most up-to-date information about your practice, the Mass Collaborative* is pleased to introduce the Standardized Provider Information Change Form. When you are changing your practice name, address, phone numbers, e-mail, billing company, or other practice information, you only need to complete this single form and send it via email, fax, or US mail to each health plan you contract with instead of completing a different form for each health plan. The following health plans now accept this form:

  • Blue Cross Blue Shield of Massachusetts
  • Boston Medical Center Healthnet Plan
  • CeltiCare Health Plan of Massachusetts
  • Fallon Community Health Plan
  • Fallon Total Care
  • Harvard Pilgrim Health Care
  • Health New England
  • Neighborhood Health Plan
  • Network Health
  • Tufts Health Plan
  • Senior Whole Health
  • Unicare

This form should not be used to submit credentialing or contractual changes. Continue to use individual health plan forms for those changes. In some circumstances, individual health plans may need to follow up with providers for additional information regarding a demographic change.


For questions about specific health plan policies or requirements, contact that health plan directly.
