Provider Enrollment Series | Updated for 2026
The Short Answer
Does a nurse need an NPI? It depends entirely on their role. Nurse Practitioners (NPs), Midwives (CNMs), and CRNAs must have one to bill insurance. Registered Nurses (RNs) generally do not need one unless they work in specialized fields like Home Health or Case Management.
One of the most common questions we get at RxCredentialing is from nursing staff unsure about their registration status. With the rise of independent practice authority for nurses in many states, the lines have blurred.
The National Provider Identifier (NPI) is a 10-digit number used to identify healthcare providers in standard transactions. If you are “invisible” to the billing system (like most floor nurses), you don’t need one. If you generate bills or referrals, you do.
