Definition

A social worker who holds a master's or doctoral degree in social work from an accredited school of social work in addition to at least two years of post-master's supervised experience in a clinical setting. The social worker must be licensed, certified, or registered at the clinical level in the jurisdiction of practice. A clinical social worker provides direct services, including interventions focused on interpersonal interactions, intrapsychic dynamics, and life management issues. Clinical social work services are based on bio-psychosocial perspectives. Services consist of assessment, diagnosis, treatment (including psychotherapy and counseling), client-centered advocacy, consultation, evaluation, and prevention of mental illness, emotional, or behavioral disturbances.

Questions

Is 1041C0700X the right taxonomy code for a clinical social worker?

Yes. 1041C0700X, Social Worker, Clinical, is the code SimpleNPI files for social workers. Related codes some choose instead: 104100000X (Social Worker), 1041S0200X (School Social Worker).

Can I change my taxonomy code later?

Yes, for free, in your NPPES account. Add the new code with its license, make it primary, and remove the old one if it no longer applies. The NPI itself never changes.

Does 1041C0700X have to match my license?

It should describe the profession your license covers. Payers compare the taxonomy with the license during credentialing, and a mismatch slows that down.
