Which number is specifically not intended for use by individual physicians when submitting claims?

The group provider number is specifically designed for use by healthcare practices or organizations rather than individual physicians. This number allows groups of providers to submit claims as a collective entity, facilitating processes when multiple providers are involved in patient care and billing. It streamlines the claims process by assigning a single identifier to the group, which can represent multiple physicians working together under the same organization.

In contrast, other identifiers such as the state license number, provider identification number (PIN), and performing provider identification number (PPIN) are intended for use by individual practitioners. The state license number identifies the physician's authorization to practice medicine within a specific state, while a PIN and PPIN are used to uniquely identify individual providers within the healthcare system, especially for claims submission, billing, and reimbursement processes.
