Indiana Is a Reduced Practice State
The American Association of Nurse Practitioners classifies Indiana 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 Indiana Medicaid (IHCP) and most commercial plans, including Anthem Blue Cross and Blue Shield, 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 an Indiana 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 Indiana's collaboration requirements, so the agreement has to be in force before the first claim to WPS Government Health Administrators. 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 Indiana NPs Ask
Do Indiana nurse practitioners need a collaborating physician to get credentialed?
Yes in practice. AANP classifies Indiana as reduced practice, and Indiana Medicaid (IHCP) and most commercial plans ask for the collaborative agreement and the physician's name and NPI with the application.
How does an Indiana NP join Indiana Medicaid (IHCP)?
Enroll with the Indiana Family and Social Services Administration through the IHCP Provider Healthcare Portal (Gainwell). Most Indiana Medicaid (IHCP) members are in managed care (1,608,993 enrolled across 6 plans in 2024), so after the state enrollment is active, each plan you want, such as Anthem Blue Cross and Blue Shield, MDwise, Managed Health Services, credentials you separately.
Can an NP licensed in Indiana see patients in a neighboring state?
Only with a license from that state, and each state's practice rules apply to the patients there. Illinois is reduced practice; Kentucky is reduced practice; Michigan is restricted practice; Ohio is reduced 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 an Indiana NP?
CAQH (DataSpring) profile build $500; Medicare enrollment $500; Indiana Medicaid (IHCP) enrollment $500; each commercial application, including Anthem Blue Cross and Blue Shield, $200 per provider. Enrollment services bill 50% at engagement and 50% at submission.
