Health Care Provider Taxonomy Codes

Last updated July 01, 2019 with Version 19.1

The Health Care Provider Taxonomy Code Set is a hierarchical code set that consists of codes, descriptions, and definitions. Healthcare Provider Taxonomy Codes are designed to categorize the type, classification, and/or specialization of health care providers.

The Health Care Provider Taxonomy code set is published (released) twice a year on July 1st and January 1st. The July publication is effective for use on October 1st and the January publication is effective for use on April 1st. The time between the publication release and the effective date is considered an implementation period to allow providers, payers, and vendors an opportunity to incorporate any changes into their systems.


Occupational Therapy Assistant - 224Z00000X

An occupational therapy assistant is a person who has graduated from an occupational therapy assistant program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE) or predecessor organizations, has successfully completed a period of supervised fieldwork experience required by the accredited occupational therapy assistant program, has passed a nationally recognized entry-level examination for occupational therapy assistants, and fulfills state requirements for licensure, certification, or registration. An occupational therapy assistant provides interventions under the supervision of an occupational therapist 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 therapy assistants 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.


Driving & Community Mobility - 224ZR0403X

Occupational therapy assistants contribute to the completion of an individualized occupational therapy driving and community mobility evaluation by administering delegated assessments and identifying findings that impact the client's occupational performance. Clients engage in the assessment and occupational profile process to customize the evaluation to their individual driving and community mobility needs. Occupational therapy assistants administer and continuously modify individualized in-vehicle and community mobility assessments within the naturalistic context of the community in response to the occupational performance and safety behaviors of the client. They also implement an individualized intervention plan, within the parameters established in collaboration with the occupational therapist that reflects the contexts of the client and meets his or her occupational performance and safety needs. Occupational therapy assistants address immediate and long-term implications of psychosocial issues related to compromised driving and community mobility throughout the occupational therapy process and makes recommendations to the occupational therapist for modification to service delivery.

Environmental Modification - 224ZE0001X

Occupational therapy assistants provide environmental modifications under the supervision of an occupational therapist. OTAs develop and implement an individualized occupational therapy environmental modification plan that reflects the relevant contexts of the client and relevant others and maximizes current and future occupational performance, safety, and participation of the client. Clients receive environmental modification recommendations and interventions that enable them to meet occupational performance and participation goals and that have adequate flexibility to accommodate for their future needs.

Feeding, Eating & Swallowing - 224ZF0002X

Occupational therapy assistants provide environmental modifications under the supervision of an occupational therapist. OTAs develop and implement an individualized occupational therapy environmental modification plan that reflects the relevant contexts of the client and relevant others and maximizes current and future occupational performance, safety, and participation of the client. Clients receive environmental modification recommendations and interventions that enable them to meet occupational performance and participation goals and that have adequate flexibility to accommodate for their future needs.

Low Vision - 224ZL0004X

Occupational therapy assistants contribute to the completion of an individualized occupational therapy low-vision evaluation under the direction and supervision of the occupational therapist to identify factors that may facilitate, compensate for, or inhibit use of vision in occupational performance. Clients are engaged in the identification of strengths, limitations, and goals as they relate to low vision to optimize independence and participation in desired occupations. Occupational therapy assistants also contribute to the development and implementation of an individualized occupational therapy low-vision intervention plan in collaboration with the occupational therapist, client, and relevant others that reflects the client?s priorities for occupational performance.
