How we build the directory

What's in the directory

We include every active provider in the NPI registry with one of these provider-type (taxonomy) codes, in the 50 states and DC. Hospitals come from CMS instead.

• Doulas (18,635 listings): NPPES codes 374J00000X
• Lactation consultants (7,818 listings): NPPES codes 163WL0100X, 174N00000X
• Midwives (11,262 listings): NPPES codes 367A00000X, 176B00000X, 175M00000X
• Birth centers (676 listings): NPPES codes 261QB0400X
• Hospitals (2,348 listings): CMS hospitals that report providing labor and delivery

A provider with several of these codes gets one listing that appears in each matching category, so a doula who is also a lactation consultant shows up on both city pages under one profile.

What we leave out

• NPIs that were deactivated and never reactivated.
• Stale records: 9,091 individual records and 680 practice listings whose newest NPPES update is older than 2016. CABC-accredited birth centers are kept regardless.
• Listings with no phone number.
• Billing networks: national companies that register NPIs at a billing office or mailbox, with toll-free numbers or out-of-state mailing addresses, rather than at a local practice. We exclude 639 organization NPIs and 136 individual NPIs of this kind, so a billing headquarters never shows up as a local provider. Clinicians at those addresses are kept under their own practice or as individuals.

How records become listings

The registry has one record per NPI. We group records at the same practice address so you can see who works where:

• Practices: an organization NPI with one of our codes, plus the clinicians registered at its address.
• Birth centers: birth-center organization NPIs, merged when several share one street address.
• Clinics and medical groups: midwives, doulas or lactation consultants registered at an OB-GYN practice, community health center or hospital address, listed under that organization's name.
• Hospitals: a CMS hospital, plus any clinicians at its street address.
• Individuals: a clinician with no organization at their address.

Privacy: city and phone only for individuals

Many doulas and lactation consultants work from home, and the address in their NPI record is often where they live. So individual providers are always shown by city and phone only, never by street address. We also hide the street for 2,953 small practices with nothing to suggest a business location, such as a suite number, a clinic-type name or more than one clinician. P.O. boxes are never shown. Birth centers, clinics and hospitals show their address.

Medicaid flags

Where a state publishes a list of Medicaid doulas we can match, we flag those listings. The wording depends on what the list means, and no listing ever says a provider “accepts Medicaid”:

• CA, Medi-Cal Doula Directory (April 2025): The state's list of enrolled Medicaid doulas. Listings say “Medi-Cal enrolled”.
• NY, NYS Medicaid Fee-for-Service Doula Directory (October 2026): The state's list of enrolled Medicaid doulas. Listings say “New York Medicaid enrolled”.
• NJ, UnitedHealthcare Community Plan of New Jersey doula list (September 2026): One Medicaid managed-care plan's doula network. Listings say “Listed on UnitedHealthcare Community Plan of New Jersey doula list”.
• MN, Minnesota Department of Health Doula Registry (September 2026): The state registry a doula joins before billing Medicaid. Listings say “Listed on Minnesota Department of Health Doula Registry”.
• OR, OHA Traditional Health Worker Registry (certified birth doulas) (October 2026): The state registry a doula joins before billing Medicaid. Listings say “Listed on OHA Traditional Health Worker Registry (certified birth doulas)”.

California and New York lists are matched by NPI. The others are matched by first and last name among that state's doulas, using phone to break ties, and a name that still matches two people is skipped. California's list is the April 2025 edition, because the state's site blocks automated downloads; listings show that date. In total, 1,370 listings carry a Medicaid flag.

Birth centers

1,510 Active organization NPIs carry the birth-center code. After removing billing shells, hospital units registered under the code, P.O. boxes and stale records, and merging NPIs at one address, we list 676 birth centers. 110 are flagged as accredited by the CABC, out of 111 on its list. Some NPPES birth centers are small midwife-run practices, so check licensing and accreditation with the center.

Hospitals

Hospitals come from the CMS Maternal Health measure (SM_7). We list the 2,256 hospitals that hold the CMS Birthing-Friendly designation and 92 that report providing labor and delivery without it. Hospitals that answered “Not Applicable” or have no data are left out, because CMS shows no evidence of obstetric services for them, so some hospitals with labor and delivery may be missing.

Profiles, city pages and order

• Organizations, birth centers, hospitals and providers on a state Medicaid list get a profile page (11,147 in all). Other individuals appear on their city and state pages with a link to claim their listing.
• A care type gets its own city page when it has 3 or more listings in that city.
• Lists use the same neutral order everywhere: providers whose main type is that category first, then organizations before individuals, larger teams, the most recently updated NPI records, and name. Nobody can pay to move up.

Known gaps

• NPI records are self-reported. A provider's address or phone can be out of date even when the record was recently updated.
• Doulas without an NPI can't appear. Many doulas on the Minnesota and Oregon registries don't have one.
• New Jersey's flag covers one Medicaid plan's doula network, because the state's full list isn't downloadable.

How to correct a listing

If you're the provider, claim your listing for free from the claim page. You sign in with your email, and once we confirm it's you, you can add a description, services, languages, hours, a photo, a website or scheduling link, or correct your phone number or office address. We review every change before it publishes. You can also ask us to remove your listing. To fix a detail at the source, update your record at nppes.cms.hhs.gov, and the next data refresh picks it up. Anyone else can report a problem through the contact form.
