Mississippi Is a Reduced Practice State
The American Association of Nurse Practitioners classifies Mississippi as reduced practice: state law requires a career-long regulated collaborative agreement with another health provider for the NP to provide patient care, or limits the setting of one or more elements of NP practice. 12 of the 50 states and DC have that classification, and they are where NP applications most often stall on agreement paperwork.
For credentialing, reduced practice means the collaborative agreement is part of the file. Expect Mississippi Medicaid and most commercial plans, including Blue Cross and Blue Shield of Mississippi, to ask for the agreement itself, the collaborating physician's name and NPI, and in some cases the physician's signature or attestation. The CAQH (DataSpring) profile has a section for the collaborating or supervising practitioner, and an empty section is one of the most common reasons a Mississippi NP application is returned.
Medicare does not ask for the agreement on the CMS-855I, but its NP rule (42 CFR 410.75) requires that you meet Mississippi's collaboration requirements, so the agreement has to be in force before the first claim to Palmetto GBA. If the collaborating physician changes, update CAQH (DataSpring) and notify every plan, since an agreement on file that has lapsed can trigger a recredentialing review.

Questions Mississippi NPs Ask
Do Mississippi nurse practitioners need a collaborating physician to get credentialed?
Yes in practice. AANP classifies Mississippi as reduced practice, and Mississippi Medicaid and most commercial plans ask for the collaborative agreement and the physician's name and NPI with the application.
How does a Mississippi NP join Mississippi Medicaid?
Enroll with the Mississippi Division of Medicaid through the MESA provider portal. Most Mississippi Medicaid members are in managed care (478,746 enrolled across 3 plans in 2024), so after the state enrollment is active, each plan you want, such as Magnolia Health Plan, UnitedHealthcare Community Plan, Molina Healthcare, credentials you separately.
Can an NP licensed in Mississippi see patients in a neighboring state?
Only with a license from that state, and each state's practice rules apply to the patients there. Alabama is reduced practice; Arkansas is reduced practice; Louisiana is reduced practice; Tennessee is restricted practice. Payer enrollment is also per state, so seeing patients across the line means a separate Medicaid enrollment and separate commercial applications there.
What does PECS charge a Mississippi NP?
CAQH (DataSpring) profile build $500; Medicare enrollment $500; Mississippi Medicaid enrollment $500; each commercial application, including Blue Cross and Blue Shield of Mississippi, $200 per provider. Enrollment services bill 50% at engagement and 50% at submission.
