NPI number for occupational therapists

Occupational therapists need an NPI for Medicare, Medicaid, school-based billing programs, early intervention and every commercial plan. The NPI goes on the claim as the rendering provider even when a facility bills.

Short answer: occupational therapists need an NPI when a payer, platform or employer puts them on a claim. The NPI is free, takes minutes, and lasts for life. SimpleNPI files it for you for free, usually within 10 minutes, or you can apply yourself at NPPES. Check the free lookup first in case you already have one.

Who asks occupational therapists for an NPI

Medicare (PECOS) and Medicaid: Enrollment starts with the NPI; many school districts bill Medicaid for OT and need each therapist's NPI.
Hospitals, SNFs and clinics: The facility bills under its Type 2 NPI and lists you as rendering provider.
Early intervention and pediatric programs: State programs identify providers by NPI.
Travel and contract agencies: Credentialing asks for it before placement.
