Healthcare M&A volume cleared $1B+ in 2025 across PE rollups (TUSK Practice Sales, Practice Transitions Group). DSO deal flow alone was 10+ practices/month in September 2025. Every one of those buyers needs the same thing: a clean physician contact list with NPI, specialty, primary practice address, license number, and a working email pattern. This actor returns that record on demand at per-call pricing.

Why this exists

Definitive Healthcare sells the physician directory market at $25,000-$100,000 per seat per year. That's the price umbrella for every healthcare-M&A team, PE rollup, MedSpa broker, and physician-recruitment firm that needs the same dataset. The NPI Registry has been free public data from CMS since 2007. Healthgrades, Vitals, and ZocDoc are public-web. State medical license boards are searchable in every US state. The data is there. Nobody has wired it into a single per-call API that returns one normalized record.

This actor does that. NPI Registry as the spine. State medical license board cross-reference for live status verification. Email guess generator for outreach. One call, one record, $0.05-$0.25 per row depending on enrichment level.

Pricing

For comparison: Definitive Healthcare seats run $25K-$100K/yr. At $0.25/record, you can pull 100,000 enriched physician records for $25,000 once. That's the price umbrella this is sitting under.

Use cases

• PE healthcare rollups building target lists across states for cardiology, orthopedics, dermatology, primary care, dental practice acquisition
• MedSpa M&A brokers identifying medical directors and specialty practice owners for M&A outreach
• Physician recruitment firms building active-license verified provider lists by specialty + region
• Medical sales reps prospecting providers in target specialties (device manufacturers, pharma, RCM)
• Healthcare research firms academic and competitive-intel firms running provider-density analyses
• Provider credentialing teams verifying NPI + license + practice address in one call

Honest tradeoffs (v1)

• State license live status: v1 wires CA Medical Board (search.dca.ca.gov) live cross-reference. CA-MBC sits behind an F5 WAF that intermittently blocks Chrome-fingerprinted requests. When the live check returns 0 rows, the actor falls back to the NPI Registry taxonomy license number with status:"unknown" and a note. FL, NY, TX coming in v2.
• Healthgrades / Vitals / ZocDoc: deferred to v2. Healthgrades and Vitals require Cloudflare bypass, ZocDoc requires Datadome bypass. Adding them is the work for v2 once the v1 dataset proves the demand.
• Email guessing: the 6 patterns generated are unverified guesses. The note on each guess says so. Pair them with my Email Validator API for SMTP-grade verification before sending outreach.
• NPI Registry specialty filter: the public CMS API does substring match on taxonomy_description. A search for "Cardiology" returns Cardiologist MDs (taxonomy 207RC0000X) plus pharmacists with cardiology certs (1835C0206X). Filter by taxonomy_code prefix 207RC for MD-only cardiologists.
• Org NPIs (NPI-2): included in search but enrichment treats them as the legal entity. For physician-level outreach, filter by enumeration_type:"NPI-1".

Test-payload short-circuit

Pass NPI 1234567890 or 0000000001 or 9999999999, or name John Doe Test, and the actor returns {ok:true, mocked:true} with no charge. Use these for CI smoke tests without burning credit.

curl-s"https://george-the-developer--physician-directory-npi.apify.actor/enrich?_test=true&npi=0000000001"\
-H"Authorization: Bearer YOUR_APIFY_TOKEN"
# {"ok":true,"mocked":true,"reason":"test-payload short-circuit, NPI Registry skipped"}
