224ZR0403X Driving and Community Mobility Occupational Therapy Assistant

Definition

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.

Where 224ZR0403X sits

• Group: Respiratory, Developmental, Rehabilitative and Restorative Service Providers — code 24 of 82 in the group
• Classification: Occupational Therapy Assistant 224Z00000X
• Specialization: Driving and Community Mobility 224ZR0403X

Choose 224ZR0403X over the general Occupational Therapy Assistant code (224Z00000X) when the provider's training or certification is specifically in driving and community mobility; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

224ZR0403X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

If 224ZR0403X is not quite right, these codes in other groups share a word with it — often the same field practised by a different kind of provider:

• 146E00000X Community Paramedic (Emergency Medical Service Providers)
• 163WC1500X Community Health Registered Nurse (Nursing Service Providers)
• 172V00000X Community Health Worker (Other Service Providers)

Using 224ZR0403X

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
