What Public CMS Data Show
Occupational Therapist: NPPES taxonomy is a reported classification, not proof of board certification.
NPI first issued
2017
The year this clinician's National Provider Identifier (NPI) was issued. An NPI is a unique 10-digit ID that US health care providers use for billing.
What this does not show: NPI first issued
NPIs have been issued only since 2005, so this year is not necessarily when the clinician started practicing.
Source: CMS NPPES NPI Registry.
Medicare assignment not listed
CMS data do not show whether this clinician accepts Medicare assignment. This does not mean they do not accept Medicare. Ask the office.
Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.

Specialties & License Numbers Reported to NPPES
NUCC Taxonomy Code: 225X00000X
An occupational therapist is a person who has graduated from an entry-level occupational therapy program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE) or predecessor organizations, or approved by the World Federation of Occupational Therapists (WFOT), or an equivalent international occupational therapy education program; has successfully completed a period of supervised fieldwork experience required by the occupational therapy program; has passed a nationally recognized entry-level examination for occupational therapists, and fulfills state requirements for licensure, certification, or registration. An occupational therapist provides interventions based on evaluation and which emphasize the therapeutic use of everyday life activities (i.e., occupations) with individuals or groups for the purpose of facilitating participation in roles and situations and in home, school, workplace, community and other settings. Occupational therapy services are provided for the purpose of promoting health and wellness and are provided to those who have or are at risk for developing an illness, injury, disease, disorder, condition, impairment, disability, activity limitation, or participation restriction. Occupational therapists address the physical, cognitive, psychosocial, sensory, and other aspects of occupational performance in a variety of contexts to support engagement in everyday life activities that affect health, well-being, and quality of life.
NUCC Taxonomy Code: 225XP0200X
Occupational therapists provide services to infants, toddlers and children who have or who are at risk for developmental delays or disabilities. Occupational therapy is concerned with a child's ability to participate in daily life activities or "occupations." Occupational therapists use their unique expertise to help children with social-emotional, physical, cognitive, communication, and adaptive behavioral challenges and to help children to be prepared for and perform important learning and school-related activities and to fulfill their rule as students. Through an understanding of the impact of disability, illness, and impairment on a child's development, plan, ability to learn new skills, and overall occupational performance, occupational therapists design interventions that promote healthy development, establish needed skills, and/or modify environments, all in support of participation in daily activities.
