Definition
Community health workers (CHW) are lay members of communities who work either for pay or as volunteers in association with the local health care system in both urban and rural environments and usually share ethnicity, language, socioeconomic status and life experiences with the community members they serve. They have been identified by many titles such as community health advisors, lay health advocates, "promotores(as), outreach educators, community health representatives, peer health promoters, and peer health educators. CHWs offer interpretation and translation services, provide culturally appropriate health education and information, assist people in receiving the care they need, give informal counseling and guidance on health behaviors, advocate for individual and community health needs, and provide some direct services such as first aid and blood pressure screening. Some examples of these practitioners are Community Health Aides or Practitioners established under 25 USC 1616 (l) under HHS, Indian Health Service, Public Health Service.

Where 172V00000X sits
- Group: Other Service Providers — code 4 of 38 in the group
- Classification: Community Health Worker 172V00000X
Community Health Worker has no specializations, so 172V00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
172V00000X 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.

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.
