Healthcare referral generation without buying a list
Referral generation programs usually buy a list, work it, and then have no way to explain why results stalled. A data-first method makes each step inspectable: you can point at the geography that was resolved, the datasets that were queried, the rows that came back, and the ranking rule that ordered them.

Step 1 — resolve the geography properly
Almost all useful healthcare data is published at county, state, CBSA or ZCTA grain. Sales territories are described in cities and metros. Naming a city and getting nothing back is the most common failure mode in this work.
Resolve the place name to state FIPS, every county it touches, place code, ZCTA and CBSA up front, then translate into whatever grain each dataset speaks — rolling ZIPs up to a county, fanning a metro out to member counties. Widening should be disclosed, not silent.
Step 2 — pull the facility and clinician universe
Depending on the offering, the universe is some combination of NPPES clinicians, CMS Care Compare facilities, SAMHSA treatment facilities, HRSA health centers, nursing homes, home health and hospice providers. These are census-style registries, not samples, so the counts are the counts.

Step 3 — rank on volume and payer mix
Medicare enrollment and Medicare Advantage penetration tell you how much of the county's senior population sits in fee-for-service versus managed care — which changes who has authority over a referral. Medicaid enrollment and drug utilization do the same for the Medicaid side. A referral target that cannot pay for your service is not a target.
Step 4 — establish need with population data
CDC PLACES gives model-based prevalence estimates at county and tract level. HRSA HPSA designations mark shortage areas. Census ACS gives age, income, insurance status and language. Together they separate 'a large county' from 'a county with the specific unmet need our service addresses.'
Step 5 — measure coverage, then re-run
Because the universe is reproducible, the same query re-run next quarter gives a comparable number. Coverage becomes a tracked metric instead of an anecdote.
What to take away
- Geography resolution is the step that silently breaks most analyses.
- Registries give counts, not samples — use them for the denominator.
- Payer mix decides whether a referral can convert.
- A reproducible universe turns coverage into a trackable metric.
