Insurance billing guides

Therapy insurance billing, state by state

Reviewed by Albert Wong, PhD, Clinical Psychologist

The machinery of insurance billing — credentialing, eligibility checks, claims, remittances — is national, but the pieces that trip therapists up are local: what the state's Medicaid program is called and how you enroll, which licensing boards payers credential under, and where to turn when an insurer drags its feet. Each guide below covers the full billing cycle with the state-specific details filled in.
