Ben Argeband, Founder & CEO of Heartbeat.ai — a practical walkthrough of what to put in a physician market-mapping sheet and how to run it week over week.
What’s on this page:
Who this is for
This is written for recruiters building a physician target market list for recurring hiring — a map that has to hold up across multiple reqs, multiple recruiters, and the slow decay that hits every contact list over time.
Physician recruiting has three predictable frictions: public sources are strong on identifiers but weak on reachability, duplicates pile up when several recruiters work the same market, and contact data goes stale fast enough to break a cadence mid-quarter.
Quick answer
- Core answer
- Build a physician market map from public identifiers, dedupe by NPI or license number, enrich the records missing usable contact info, then run a repeatable outreach sequence with weekly refresh and suppression built in.
- Planning note
- Physician placements typically require a meaningful volume of outreach attempts, so size your cohort with that in mind rather than assuming a short list will get you to a hire.
- Best for
- Recruiters building a physician target market list for recurring hiring.
Compliance & safety
This method is for legitimate recruiting outreach only. Respect candidate privacy, opt-out requests, and applicable data and communications laws. Nothing here is medical or legal advice.
The map, enrich, sequence workflow
Mapping gives you a stable identifier spine that survives refresh cycles. Enrichment adds the reachability you need to actually connect. Sequencing turns the map into weekly submittals instead of a one-time export that goes stale.
- Map: start with public sources to capture NPI and license fields, plus specialty and location.
- Enrich: add mobile, direct, and email fields, along with provenance and last-verified dates.
- Sequence: run consistent outreach, log outcomes, and feed suppression and updates back into the map.
Dedupe by NPI or license before you enrich — merging after outreach starts wastes attempts and burns trust with candidates who get contacted twice.
Where market mapping pays back fastest
- New req launch: stand up a cohort quickly because the identifier spine already exists.
- Recurring quarterly hiring: reuse the same cohort and refresh what decayed instead of rebuilding from scratch.
- Facility expansion: clone the schema, adjust the boundary, and keep dedupe rules consistent across markets.
- Team recruiting: prevent duplicate outreach with cohort ownership, suppression, and a merge log.
Step-by-step method
Step 1: Define the market boundary
Write the boundary in one sentence before touching any data:
- Specialty scope: which physician specialty or specialties this req cycle targets.
- Geography: the area you can realistically hire into.
- Setting: hospital-employed, private practice, or academic — this changes the contact path.
Create a cohort label that encodes the boundary, for example: Specialty | Market | Setting | Wave.
Step 2: Build the identifier spine from public sources
Government sources give you stable identifiers and an audit trail. For physicians, the most useful stable identifier is the NPI, maintained through the federal NPPES registry.
- Pull NPI records for your boundary and capture the fields you’ll use for matching and refresh.
- Where available, capture license number, state, and license status from state verification sources.
At this stage you’re not chasing the best phone number yet. You’re building a backbone that can survive merges and weekly refreshes.
Step 3: Add practice signals without making them your primary key
Professional networking profiles can help validate specialty focus, current org, and location — but they shouldn’t anchor your dedupe logic.
- Capture profile URL, current org, and location as supporting signals.
- If a practice-signal source conflicts with NPI or license data, treat NPI/license as the anchor and flag the conflict for manual review.
Step 4: Normalize names and organizations
Normalize the fields that cause false duplicates:
- Name: split into first, middle, last, suffix; keep a separate display_name if needed.
- Organization: store org_raw and org_normalized, stripping punctuation and standardizing abbreviations.
- Location: store city, state, ZIP, and a separate market field matching your boundary definition.
Step 5: Dedupe using NPI and license matching rules
Make dedupe rules explicit so every recruiter merges the same way:
- Primary key: NPI, exact match.
- Secondary key: license number plus state, exact match, used when NPI is missing or ambiguous.
- Manual review bucket: name, city, specialty, and org matches only — never auto-merge on these alone.
A dedupe event is when two or more rows represent the same physician and get merged into one canonical record, preserving all source references. License matching keeps the map stable when sources don’t carry NPI cleanly.
Step 6: Enrich for reachability and track provenance
Once the spine is clean, enrich the records so they’re usable for outreach. Many teams use public sources and practice-signal platforms for mapping, then fill missing contact fields through a dedicated enrichment step.
- Add separate fields for mobile, direct line, office line, and email.
- Store contact_source and contact_last_verified_date so refresh decisions are based on evidence, not guesswork.
- Maintain a suppression flag for opt-outs and do-not-contact requests.
Re-enrich a record when:
- An email bounces.
- A call outcome comes back as wrong number or disconnected.
- The contact_last_verified_date is older than your team’s refresh cadence allows.
The goal at this stage is simple: fewer dead dials, fewer bounces, faster submittals. A provider that can supply ranked mobile numbers by answer probability can shorten this loop, but the underlying discipline — separating fields, tracking provenance, refreshing on trigger — matters more than any single vendor.
Step 7: Sequence outreach and feed outcomes back into the map
Don’t treat the map as a static export. Treat it as a system where every outcome updates suppression, verification dates, and next-touch routing.
- Run a consistent outreach sequence — call, email, follow-up.
- Log outcomes: connected, wrong number, voicemail, bounce, reply, opt-out.
- Update the map by replacing bad contacts, suppressing opt-outs, and tagging reached versus not reached.
The trade-off is real: you spend more time upfront on structure, but you stop paying a rebuild tax every time a new req opens.
Step 8: Assign ownership and suppression governance
Market mapping tends to fail in multi-recruiter teams when ownership is vague. Put governance directly into the sheet:
- Single owner per cohort: every row has an owner for the current wave, even if ownership rotates next wave.
- Central suppression: opt-outs and do-not-contact requests live in the master map, not personal notes.
- Merge log: simple merged_by and merged_date fields are enough to keep dedupe auditable.
Team handoffs
- Recruiting ops or lead recruiter: owns dedupe rules, merge conflicts, and the weekly dedupe run.
- Each recruiter: owns outcome logging — wrong number, bounce, reply, opt-out — and keeps notes minimal.
- Cohort owner: owns suppression enforcement and decides when to refresh enrichment for that cohort.
Diagnostic table
Use this to figure out why your current map isn’t producing reachable candidates fast enough.
| Symptom | Likely cause | Fix in the map | Fix in the workflow |
|---|---|---|---|
| High wrong-number rate on calls | Office main lines stored as the primary phone field | Separate mobile vs direct vs office; store provenance and last-verified date | Prioritize mobile/direct; route office lines to a gatekeeper script |
| Low answer rate | Calling at the wrong times or relying on office lines | Tag preferred call windows when learned; keep office lines separate from mobile/direct | Shift call windows by cohort; prioritize mobile/direct before office lines |
| Duplicates across recruiters | No canonical key; inconsistent name formatting | Make NPI the primary key; add license matching as secondary | Centralize the master sheet; enforce merge rules and a merge log |
| Email bounces rise over time | List decay; no suppression or refresh routine | Add bounce flag, last sent date, last delivered date | Weekly refresh and suppression before each send |
| Low coverage in a cohort | Boundary too tight, missing identifiers, or inconsistent suppression | Audit NPI/license fields, expand boundary if needed, separate suppressed from not-yet-enriched | Re-pull identifiers from public sources, re-run dedupe, enrich missing channels before sequencing |
Weighted checklist
Score your market map readiness before launching outreach. Total is 100 points on an internal rubric — if you’re under 70, fix the sheet before scaling outreach.
- (25) NPI present and validated for most rows in scope (set your own threshold by cohort and track it weekly).
- (15) License matching fields present — state, number, and status where available.
- (15) Dedupe rules documented and followed: NPI first, license second, manual review third.
- (10) Merge log maintained with merged_by, merged_date, merge_reason.
- (15) Contact fields separated into mobile/direct/office/email with source and last-verified date.
- (10) Suppression fields exist: opt-out, do-not-contact, wrong specialty, retired/moved.
- (10) Cohort definition is set and used for assignment and reporting.
A cohort is a labeled subset of the map used for routing and measurement — for example, Hospitalist | Metro North | Employed | Wave 1. Cohorts need to stay consistent enough to compare week over week.
Outreach templates
These are built for physician recruiting realities: short windows, gatekeepers, low tolerance for fluff. Customize the bracketed fields and keep the first touch short.
Template 1: Direct-to-physician voicemail (mobile)
“Hi Dr. [Last], this is [Name]. I’m recruiting for a [Specialty] opening with [Org] near [City]. If you’re open to a quick, confidential chat, call or text me at [Number]. If not, reply ‘no’ and I’ll suppress future outreach. Thanks.”
Template 2: Gatekeeper call opener (office line)
“Hi—can you help me reach Dr. [Last]? This is recruiting outreach about a [Specialty] opportunity. What’s the best number or time window to reach them directly?”
Template 3: Email (first touch)
Subject: [Specialty] near [City] — quick question
“Dr. [Last] — I’m recruiting for a [Specialty] position with [Org] near [City]. Are you open to a brief call this week, or should I close the loop? If you prefer text, reply with a number and I’ll keep it short.”
Template 4: Email follow-up with specifics
Subject: Re: [Specialty] near [City]
“Following up once. I can send comp range, call schedule, and clinic mix in one message. If you’re not interested, reply ‘no’ and I’ll suppress future outreach.”
Common pitfalls
Pitfall 1: Treating a list like a market map
A list is a one-time export. A market map is a maintained dataset with identifiers, provenance, and outcomes attached. If you can’t say where a contact came from and when it was last verified, you don’t have something you can run weekly.
Pitfall 2: Deduping after outreach starts
If two recruiters contact the same physician because dedupe by NPI or license didn’t happen first, you burn trust and waste attempts. Do the merge work before the first send, not after.
Pitfall 3: No suppression discipline
Opt-outs, wrong specialty, retired, moved — these need centralized suppression. If it lives in personal notes, you’ll keep re-contacting the same people every quarter.
Pitfall 4: A sheet that can’t survive weekly refresh
Most teams fail here because the schema itself breaks under refresh. Use a canonical column set that supports mapping from public sources, then enrichment, then sequencing, without breaking dedupe.
Copy/paste market map columns: physician_id, npi, license_state, license_number, first_name, last_name, specialty_primary, city, state, org_raw, org_normalized, profile_url, phone_mobile, phone_direct, phone_office, email_primary, contact_source, contact_last_verified_date, cohort, owner, status, suppression_reason, merged_by, merged_date, merge_reason, last_touch_date, notes.
| Column | Type | Required? | Notes / rules |
|---|---|---|---|
| physician_id | string | Yes | Internal stable ID — do not change once assigned. Generate once on first import. |
| npi | string | Preferred | Primary dedupe key. Exact match only. |
| license_state | string | Preferred | Used with license_number for secondary dedupe. |
| license_number | string | Preferred | Secondary dedupe key with license_state. |
| specialty_primary | string | Yes | Use a controlled list for reporting consistency. |
| org_normalized | string | No | Lowercase, strip punctuation, standardize abbreviations. |
| contact_source | string | No | e.g., public source, practice-signal platform, enrichment provider. |
| contact_last_verified_date | date | No | Update whenever you confirm deliverability or a connection. |
| cohort | string | Yes | Used for routing and measurement. |
| suppression_reason | string | No | opt_out, wrong_specialty, retired, moved, do_not_contact, duplicate. |
How to improve results
Improvement comes from two loops working together: better reachability data, and better routing and cadence decisions. Working only one loop tends to plateau quickly.
Define the metrics
- Deliverability rate = delivered emails / sent emails, per 100 sent.
- Bounce rate = bounced emails / sent emails, per 100 sent.
- Connect rate = connected calls / total dials, per 100 dials.
- Answer rate = human answers / connected calls, per 100 connected calls.
- Reply rate = replies / delivered emails, per 100 delivered.
Coverage is the percent of physicians identifiable within your market boundary who exist in your map with a valid identifier match (NPI and/or license) and at least one usable, non-suppressed outreach path.
Weekly refresh routine
- Import updates from public sources — new NPIs, address changes — plus internal notes affecting suppression.
- Run dedupe using NPI and license matching rules; merge while preserving provenance.
- Refresh enrichment for records missing mobile/direct/email or with stale verification dates.
- Apply suppression before any outreach — opt-outs, do-not-contact, wrong specialty.
- Re-cohort if the req boundary changed — new facility, new radius, new specialty mix.
- Launch the sequence and log outcomes back into the map the same day where possible.
Measurement plan
Run a cohort-based weekly report covering:
- Map size (rows after dedupe) by cohort.
- Coverage by cohort, split into phone-available, email-available, both.
- Suppression rate = suppressed records / total records, per 100, by cohort.
- Outreach outcomes using the deliverability, bounce, connect, answer, and reply definitions above.
- Speed to first reach: median days from new to reached status, by cohort.
If/then actions when metrics drift
| If you see… | It usually means… | Do this next |
|---|---|---|
| Bounce rate rising | Decay or bad domains in the cohort | Suppress bounces, refresh enrichment for that cohort, re-send only to delivered addresses |
| Low connect rate | You’re dialing office lines or stale numbers | Prioritize mobile/direct fields, move office lines to a gatekeeper workflow, refresh phones flagged wrong-number |
| Good deliverability but low reply rate | Message isn’t specific enough to the role | Add call schedule, setting, and location specifics to follow-up; tighten the ask to one question |
| Suppression rate climbing | You’re re-touching the same market without respecting prior outcomes | Audit suppression reasons, enforce centralized suppression, rotate cohorts instead of blasting the full map |
Plan cohort size around expected outreach attempts per placement: if the cohort is too small after dedupe and suppression, you’ll run out of reachable candidates before reaching submittals.
Legal and ethical use
Market mapping is legitimate when it supports lawful recruiting outreach and respects candidate preferences.
- Use data from public sources and reputable providers, and document sources in your sheet.
- Honor opt-out requests quickly and permanently — suppression should be centralized.
- Follow applicable privacy and communications laws for your jurisdiction and the candidate’s location.
- Don’t store sensitive personal data you don’t need to recruit — keep notes minimal and job-relevant.
- Keep suppression reasons standardized so they’re auditable and consistently applied.
- Don’t represent your map as complete or guarantee completeness — list decay is real and ongoing.
Evidence and trust notes
Building a market map means making operational decisions based on data quality. Anchor your identifier spine to NPI and keep a source trail so refresh and dedupe stay auditable. NPI is an identifier for matching and dedupe — it is not a guarantee of reachability.

FAQs
What is market mapping in physician recruiting?
It’s the process of building and maintaining a structured dataset of physicians in a defined boundary — specialty plus geography — anchored by NPI/license, then adding reachability fields for outreach.
Where should I start building a physician market map?
Start with public sources for identifiers (NPI and license where available), add practice-signal sources for context, then enrich for phones and emails last.
How do I dedupe a physician market map correctly?
Dedupe by NPI first, exact match. If NPI is missing or inconsistent, use license matching — state plus license number. Put name/org-only matches into a manual review bucket rather than auto-merging.
How big should my market map be?
Big enough to support your outreach reality after dedupe and suppression. Plan cohort size around expected outreach attempts per placement, not around how many names you can export.
How do I keep the map fresh without rebuilding it?
Run a weekly refresh routine: import identifier updates, dedupe, refresh enrichment for missing or stale contacts, apply suppression, then sequence outreach and log outcomes back into the map.
Next steps
- If you need a starting dataset, see physician list by specialty and state and adapt it to the CSV schema above.
- If your issue is missing phones or emails, read physician contact enrichment for what to enrich and how to track provenance.
- If you’re merging multiple sources, use NPI and license matching to tighten dedupe and reduce duplicate outreach.
- When you’re ready to operationalize this, start free search & preview data and build your first cohort with enrichment and suppression from day one.
