Taxonomy audit for home health operators
Providers may report multiple taxonomies, one is primary, and local specialty vocabularies rarely map one-to-one. This guide applies the work to agency and clinician rosters and branch names.
CHECK YOUR ROSTER
Upload your agency and clinician roster to compare taxonomy codes and specialty descriptions.
The same validator used on the homepage: local checksum checks, live public NPPES lookup, cautious differences, and clean export.
DIRECT ANSWER
Agency organizations and clinicians coexist while service areas may not match one public practice address. For taxonomy audit, Providers may report multiple taxonomies, one is primary, and local specialty vocabularies rarely map one-to-one.
How to interpret the evidence

Check the primary flag, secondary codes, local mapping, and update date before escalating. Preserve branch names as a separate consideration for home health operators.
| Roster input to retain | Public NPPES evidence to append |
|---|---|
| clinician_npi | organization name |
| service_area | taxonomy |
| specialty label | secondary taxonomies |
| taxonomy code | descriptions |
FICTIONAL OPERATIONAL EXAMPLE
taxonomy audit in a fictional agency and clinician roster
During a fictional taxonomy audit review, a agency and clinician roster contains 65 agencies and 1,200 field clinicians. One row for Quinn Harper, RN / Fictional Hearth Home Health reaches review because public record used as proof of certification.
For this taxonomy audit review, the source retains clinician_npi, service_area, clinician_npi for traceability.
Check the primary flag, secondary codes, local mapping, and update date before escalating. The reviewer also checks branch names.
A defensible workflow
- 01
Retain the local specialty and code.
- 02
Retrieve all reported NPPES taxonomies.
- 03
Identify primary without discarding secondary codes. Retain clinician_npi as operational context.
- 04
Compare codes before descriptions.
- 05
Route differences for contextual review.
Common errors in this workflow
- 01secondary taxonomy mistaken for primary
- 02difference called a credential failure
- 03public record used as proof of certification
- 04branch brand mistaken for legal name
