your cohort stays accurate enough to recruit against.<\/dd>\n<dt>Key insight<\/dt>\n<dd>NPI taxonomy is self-reported at enrollment and not continuously audited, so codes can go stale \u2014 treat

safety<\/strong><\/p>\n<p>This method is for legitimate recruiting outreach only. Respect candidate privacy, opt-out requests, and local data laws. Heartbeat does not provide medical advice or legal counsel.<\/p>\n<\/blockquote>\n<h2><span class=\"ez-toc-section\" id=\"Taxonomy_is_a_hint_not_ground_truth\"><\/span>Taxonomy is a hint, not ground truth<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Taxonomy is structured and scalable, which is why it&#8217;s useful for segmentation. But it isn&#8217;t a live feed of what a clinician is practicing today. Providers select a taxonomy code when they apply for an NPI or update their NPPES record, and that code can sit unchanged for years even as a career shifts. If you treat a taxonomy code as fact, you&#8217;ll mis-bucket people and burn call blocks on the wrong pitch.<\/p>\n<p>NPPES \u2014 the National Plan and Provider Enumeration System \u2014 is the CMS system where taxonomy codes are published alongside each NPI record. A provider can list more than one taxonomy code but must flag one as primary, and codes are drawn from the National Uniform Claim Committee (NUCC) code set, which is refreshed twice a year.<\/p>\n<p>The trade-off: taxonomy gives you fast cohort construction, but it creates false precision unless you verify it against other signals.<\/p>\n<p>The goal of NPI taxonomy specialty mapping isn&#8217;t perfect specialty accuracy. The goal is a cohort that&#8217;s directionally correct, contactable, and quick to verify.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Step-by-step_method\"><\/span>Step-by-step method<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Step_1_Pull_taxonomy_from_NPPES_and_keep_the_raw_codes\"><\/span>Step 1: Pull taxonomy from NPPES and keep the raw codes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Start with the provider&#8217;s NPPES record and capture:<\/p>\n<ul>\n<li>NPI<\/li>\n<li>All taxonomy codes on file, not just the first one<\/li>\n<li>The primary taxonomy indicator, if present<\/li>\n<li>Practice address and mailing address, useful for later verification<\/li>\n<\/ul>\n<p>Keep the raw codes even after you map them into buckets. Your mapping rules will evolve, and you&#8217;ll want to re-map without re-pulling everything from scratch.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_2_Build_recruiter-facing_buckets_%E2%80%94_dont_mirror_the_taxonomy_list\"><\/span>Step 2: Build recruiter-facing buckets \u2014 don&#8217;t mirror the taxonomy list<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Taxonomy can be granular down to subspecialty. Recruiting workflows need buckets that match how you staff and how clients buy. Build a small set of buckets and map several taxonomy codes into each one.<\/p>\n<p>This is where you avoid false precision: you&#8217;re not claiming the code equals the job title, you&#8217;re using it to route the provider into the right verification path.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_3_Add_two_confirmation_signals_before_treating_a_bucket_as_ready\"><\/span>Step 3: Add two confirmation signals before treating a bucket as ready<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Taxonomy alone isn&#8217;t enough. Add at least two independent signals that cut wasted outreach:<\/p>\n<ul>\n<li><strong>License match:<\/strong> confirm active license state(s) and name alignment (see <a href=\"http:\/\/heartbeat.ai\/resources\/provider-contact-data\/npi-license-matching\/\">NPI-to-license matching workflow<\/a>).<\/li>\n<li><strong>Affiliation signal:<\/strong> hospital or clinic directory listing, group site bio, or department page.<\/li>\n<li><strong>Recent activity signal:<\/strong> a publication, conference listing, or other public professional activity \u2014 use cautiously, since some of these sources lag.<\/li>\n<\/ul>\n<p>If you&#8217;re tempted to buy a static list instead of verifying: static lists decay quickly as providers change roles, states, or affiliations. The more durable approach pairs access with ongoing refresh, verification, and suppression rather than a one-time export.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_4_Assign_a_confidence_label_and_store_the_reasoning\"><\/span>Step 4: Assign a confidence label and store the reasoning<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When you build a cohort, don&#8217;t store a single specialty field.
