Delaware Is a Full Practice State
The American Association of Nurse Practitioners classifies Delaware as full practice: state law lets nurse practitioners evaluate patients, diagnose, order and interpret tests, and prescribe under the exclusive licensure authority of the state board of nursing. 28 of the 50 states and DC have that classification.
For credentialing, full practice means the application is about you alone. Delaware Medicaid and the commercial plans in Delaware generally do not ask for a collaborating physician, so the fields that hold up NP files in other states are simply absent. Medicare's rule for NP services (42 CFR 410.75) defers to state law on collaboration, and where state law is silent it expects the NP to document their scope of practice and how they work with physicians on issues outside it. Enrollment itself runs through PECOS and Novitas Solutions on the CMS-855I like any other independent practitioner.
What still slows Delaware NPs down is the business side: an NP-owned entity needs its own Type 2 NPI, a group enrollment and a reassignment for each clinician, and some commercial plans review NP-owned practices more slowly than physician groups. If you are new to independent practice, confirm with the board whether any transition-to-practice hours apply to you before the applications go in, because payers will ask for the license status that results.

Questions Delaware NPs Ask
Do Delaware nurse practitioners need a collaborating physician to get credentialed?
No. AANP classifies Delaware as full practice, so payers generally do not require a collaborating physician on an NP application. Check with the board of nursing whether any transition-to-practice requirement applies to a newly licensed NP.
How does a Delaware NP join Delaware Medicaid?
Enroll with the Delaware Division of Medicaid and Medical Assistance through the Delaware Medical Assistance Portal (Gainwell). Most Delaware Medicaid members are in managed care (219,167 enrolled across 3 plans in 2024), so after the state enrollment is active, each plan you want, such as Highmark Health Options of Delaware, AmeriHealth Caritas of Delaware, Delaware First Health, credentials you separately.
Can an NP licensed in Delaware see patients in a neighboring state?
Only with a license from that state, and each state's practice rules apply to the patients there. Maryland is full practice; New Jersey is reduced practice; Pennsylvania 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 a Delaware NP?
