How to Find Pathologists by Zip Code
Data sourced from live CMS NPI Registry API v2.1 queries, run June 13, 2026. All provider counts are real API responses. Raw query results are available for download. See methodology below.
taxonomy_description=Anatomic+Pathology+%26+Clinical+Pathology — NUCC code 207ZP0102X. This is the most unguessable taxonomy string in the registry for a common specialty. "Pathologist" returns zero. "Anatomic Pathology" alone and "Clinical Pathology" alone are separate narrower codes that, together, still do not equal the combined AP&CP population. The ampersand in the string must be URL-encoded as %26. This guide covers the correct string, all subspecialty codes, real counts from 9 markets, and why pathology data is unusually clean.
•
taxonomy_description=Pathologist → 0 results• The correct base string for a general pathologist is
Anatomic Pathology & Clinical Pathology (207ZP0102X)•
Anatomic Pathology alone and Clinical Pathology alone are separate, narrower codes — each returns 200+ nationally, but the combined AP&CP code is the standard enrollment for most general pathologists• Subspecialties (Cytopathology, Dermatopathology, Molecular Genetic Pathology, Forensic Pathology) are all separate strings that require independent queries
Pathologists in the NPI registry: real counts from 9 markets

Entity type: 118 NPI-1 (individual pathologists) / 10 NPI-2 (lab groups and pathology organizations)
Credential breakdown (NPI-1): M.D. 54, MD 45, M.D. (PhD/MBBS variants) 19
Key insight: Pathology data is unusually clean — almost exclusively MD physicians with no meaningful credential noise from non-physician providers. The 10 NPI-2 records are pathology group practices and lab organizations. Because pathologists work in hospital and reference labs rather than outpatient offices, their NPI practice address often reflects the hospital or lab system — important context when using address data to segment accounts by institution.
Pathology taxonomy strings
All pathology-related taxonomy strings are separate NUCC codes. All were verified live on June 13, 2026 with 200+ national results.
| Specialty | Taxonomy string (exact) | NUCC code | National sample (June 2026) |
|---|---|---|---|
| General pathologist (base) | Anatomic Pathology & Clinical Pathology | 207ZP0102X | 200+ (capped nationally) |
| Anatomic pathology only | Anatomic Pathology | 207ZP0101X | 200+ |
| Clinical pathology only | Clinical Pathology | 207ZC0500X | 200+ |
| Cytopathologist | Cytopathology | 207ZC0006X | 200+ |
| Dermatopathologist | Dermatopathology | 207ZD0900X | 200+ |
| Molecular genetic pathologist | Molecular Genetic Pathology | 207ZP0213X | 200+ |
| Forensic pathologist | Forensic Pathology | 207ZF0201X | 200+ |

How to search pathologists by zip code — step by step
Open the NPI registry
Go to npiregistry.cms.hhs.gov or open the getdork physician search. In the raw API, URL-encode the ampersand as %26.
Set the taxonomy string to Anatomic Pathology & Clinical Pathology
In getdork, the correct string is selected from the specialty dropdown. In the raw API: taxonomy_description=Anatomic+Pathology+%26+Clinical+Pathology. This is the canonical base enrollment for most general pathologists.
Use a zip radius — pathologists bill from hospital addresses
Pathologists work in hospital labs, so their NPI address is the hospital or lab, not a private office. A city filter should capture most hospital-based records if the hospital is within city limits. A 25–50 mile radius catches suburban hospital campuses.
Add subspecialty queries for targeted call lists
For genomic testing or molecular diagnostic platforms: add Molecular Genetic Pathology. For dermpath-specific tools: add Dermatopathology. For cytology consumables: add Cytopathology. Each query runs independently and may return different providers.
Export to CSV (Pro)
Export captures NPI, name, credential, entity type, address, and phone. For NPI-2 records, the organization name identifies the lab system — useful for grouping pathologists by institution in your CRM.
Radius guidance for pathology territory planning
| Market type | Recommended radius | Rationale |
|---|---|---|
| Dense urban (NYC, Chicago, LA) | 15–25 miles | All cap at 200+; narrow radius focuses on a manageable segment |
| Mid-size metro (Memphis) | 25–40 miles | 128 complete records; radius adds suburban hospital campuses |
| Small state (Vermont) | Statewide or 50 miles | 86 total statewide — manageable as a single territory sweep |
| Sparse rural (Wyoming) | Statewide — 30 total | Plan the full state as a single territory; 30 is the complete call list |

Frequently asked questions
Why does "Pathologist" return zero results in the NPI registry?
The NPI API uses NUCC specialty strings, not job titles. "Pathologist" has no matching taxonomy code. The correct general-pathologist string is Anatomic Pathology & Clinical Pathology (207ZP0102X). We confirmed live on June 13, 2026: taxonomy_description=Pathologist = 0 results.
What is the difference between "Anatomic Pathology & Clinical Pathology", "Anatomic Pathology" alone, and "Clinical Pathology" alone?
Three separate NUCC codes. The combined AP&CP code (207ZP0102X) is the standard dual-board enrollment held by most general pathologists who practice both anatomic work (tissue biopsies, surgical specimens) and clinical lab oversight (hematology, chemistry, microbiology). AP alone (207ZP0101X) covers pathologists focused only on tissue work; CP alone (207ZC0500X) covers laboratory medicine specialists without anatomic work. Querying only AP or only CP will miss pathologists enrolled under the combined code. All three return 200+ nationally.
Why do pathology counts vary so widely between Vermont and Wyoming?
Vermont returned 86 statewide; Wyoming returned 30. Vermont has a higher academic and community hospital density relative to its population — the University of Vermont Medical Center and a network of community hospitals support a larger pathology workforce. Wyoming has fewer hospitals and more concentrated pathology resources. Both are complete totals (no 200-cap). Wyoming is a single-territory call list at 30 providers.
Do pathology subspecialists — cytopathologists, dermatopathologists — appear in an AP&CP query?
Only if they also enrolled under the AP&CP base code. Subspecialists enrolled only under Cytopathology, Dermatopathology, or Molecular Genetic Pathology will not appear in the base AP&CP query. For a complete pathologist call list specific to your product, run the base query plus the relevant subspecialty queries (Cytopathology for cytology tools, Dermatopathology for dermpath diagnostics, Molecular Genetic Pathology for NGS platforms).
What does a Memphis pathologist call list actually contain, and how clean is the data?
Memphis: 128 records (118 NPI-1 / 10 NPI-2), all MD physicians, essentially no credential noise from non-physician providers. This makes pathology one of the cleaner specialties in the registry. The 10 NPI-2 records are pathology group and lab organization accounts. Pathologists bill from hospital and lab addresses, so the address field maps directly to the institution — useful for segmenting your territory by health system.
What lab-device and diagnostics products map to a pathologist call list?
A base AP&CP call list supports: anatomic pathology instruments (tissue processors, microtomes, slide stainers), immunohistochemistry reagent systems, digital pathology platforms (whole-slide scanners, image analysis), LIS platforms, molecular diagnostics systems (NGS, PCR), and hematology analyzers. Add Cytopathology for cytology staining and liquid-biopsy tools; Dermatopathology for immunofluorescence systems; Molecular Genetic Pathology for genomic test platforms targeting precision oncology workflows.
Methodology
All counts come from direct CMS NPI API v2.1 queries run June 13, 2026 using the exact string
Anatomic+Pathology+%26+Clinical+Pathology. The gotcha string Pathologist
was verified to return 0 results on the same date. NUCC codes were extracted from the
taxonomies[].code field in live API responses. The 200-record cap applies; markets showing
"200+" have actual totals beyond what the API returns in a single request.
