Geriatric Medicine. The practitioner title "Geriatrician" returns zero results. Geriatric medicine splits across two NUCC parent codes — Family Medicine path (207QG0300X) and Internal Medicine path (207RG0300X) — both captured by a single Geriatric Medicine query.
taxonomy_description=Geriatrician → 0 resultstaxonomy_description=Geriatric+Medicine → 36 records in Memphis, 42 in Vermont, 14 in Wyoming statewide.Geriatric medicine is reached through two separate training paths, and the NPI registry encodes those paths in the taxonomy string itself. A physician who did Internal Medicine then geriatric fellowship has a different NUCC code than one who did Family Medicine then geriatric fellowship — but a single Geriatric Medicine query captures both, because the API prefix-matches against the full descriptor.

| NUCC code | Taxonomy string (exact) | Training path | Memphis count |
|---|---|---|---|
| 207QG0300X | Family Medicine, Geriatric Medicine |
Family Medicine residency + geriatric fellowship | 11 |
| 207RG0300X | Internal Medicine, Geriatric Medicine |
Internal Medicine residency + geriatric fellowship | 11 |
Both codes are captured by the query taxonomy_description=Geriatric+Medicine because the NPI API prefix-matches: "Geriatric Medicine" matches both "Family Medicine, Geriatric Medicine" and "Internal Medicine, Geriatric Medicine" as substrings. You do not need to run two separate queries.
Query with taxonomy_description=Geriatric+Medicine. This returns both the Family Medicine and Internal Medicine training paths in a single pass.
Geriatric medicine has significantly fewer practitioners than primary care. Wyoming has only 14 statewide; Vermont has 42. In rural states, plan for a 75–100 mile radius. In mid-size metros, 25 miles covers the concentrated academic-center population.

&state=VT&limit=200The high NPI-2 proportion in geriatric medicine means some records represent institutional programs, not individual prescribers. For a pharma call list, filter to NPI-1 and MD/DO credentials. For hospital contracting or program-level access, the NPI-2 records are your starting point.
The taxonomies[].desc field in each record tells you whether a physician came through Family Medicine or Internal Medicine. This is directly visible in the raw NPI response and can help you understand the clinical context — FM-trained geriatricians often practice in community and long-term care settings; IM-trained geriatricians more often in academic inpatient consultation.
The getdork physician search tool sends the correct string, applies radius filtering, and produces a CRM-ready CSV for Pro users. Given how small the geriatric call list is in most territories, the full statewide list often fits in a single export.
| Market type | Suggested radius | Notes |
|---|---|---|
| Dense urban (NYC, Chicago) | 15–25 miles | Caps at 200+; academic medical centers dominate |
| Mid-size metro (Memphis, Nashville, Phoenix) | 25–50 miles | 36–88 records; completable with a single query |
| Rural state (Wyoming, rural VT) | 100 miles or statewide | Wyoming: only 14 statewide; statewide query is correct approach |
The getdork physician search sends Geriatric Medicine automatically, applies ZIP-radius filtering, and returns both Family Medicine-path and Internal Medicine-path geriatricians in a single result set. Pro users export to CSV.
The NPI registry uses NUCC taxonomy description strings, which are field-name-based — not practitioner-title-based. There is no NUCC code with the description "Geriatrician." The correct string is Geriatric Medicine. This follows the same pattern as the rest of the NUCC taxonomy: "Cardiologist" returns zero (use "Cardiovascular Disease"); "Allergist" returns zero (use "Allergy & Immunology"). The API returns nothing when a wrong string is used — silently, with no error message.
207QG0300X = Family Medicine, Geriatric Medicine (FM residency + geriatric fellowship). 207RG0300X = Internal Medicine, Geriatric Medicine (IM residency + geriatric fellowship). In Memphis (June 2026), the two codes split evenly: 11 FM-path and 11 IM-path geriatricians. FM-trained geriatricians more commonly practice in community long-term care settings; IM-trained geriatricians more commonly in academic inpatient consultation. Both are returned by a single Geriatric Medicine query.
Vermont statewide returned 42 records; Wyoming returned 14 — a 3:1 ratio despite similar geographic size. Vermont's count reflects the University of Vermont Medical Center's academic geriatric program concentration in Burlington. Wyoming's 14 geriatricians are spread across a state 2.5× the size of Vermont. Both totals are small enough that your complete territory list is achievable in a single statewide query.
In Memphis (36 total, June 2026), 15 were NPI-2 — notably high at 42% of the result set. Geriatric medicine programs frequently operate as hospital-based consultation services, memory care centers, ACE (Acute Care for Elders) units, and academic faculty practices with an institutional NPI-2. For a pharma rep, NPI-2 records here often represent the program director's institutional account — where formulary inclusion decisions are made — rather than individual prescribers.
Geriatric physicians are primary prescribers of Alzheimer's disease therapeutics (cholinesterase inhibitors, memantine, anti-amyloid biologics), osteoporosis agents, polypharmacy management tools, incontinence and fall-prevention products, and long-term care formulary items. They also consult on deprescribing — removing medications added by other physicians — which is relevant for medication reconciliation and management-device companies. Given the small call list size in most territories, a complete geriatric list is achievable quickly.
No. Geriatric psychiatrists enumerate under "Psychiatry & Neurology, Geriatric Psychiatry" (2084G0000X) — a separate NUCC string not returned by a Geriatric Medicine query. Geriatric-certified nurses enumerate under nursing taxonomy codes. The Geriatric Medicine query returns only the two physician codes (207QG0300X and 207RG0300X). For geriatric mental health prescribers, run a separate Geriatric Psychiatry query.
