What Meridian did
Dr. Shah already had a Type 1 NPI from residency. Alex applied for Meridian’s Type 2 NPI through NPPES the day the PC’s EIN arrived, approved in four business days. Dr. Shah’s CAQH profile took nine days to complete because the malpractice certificate of insurance hadn’t been issued yet.The two kinds of NPI
The National Provider Identifier is a 10-digit number that identifies healthcare providers in HIPAA standard transactions. It is issued free by CMS through the National Plan and Provider Enumeration System (NPPES) and it never expires.1
A Type 1 NPI follows the clinician, not the practice. Dr. Shah’s NPI from residency is the same one Meridian bills under. Clinicians who apply for a second Type 1 NPI at a new job create a duplicate that causes claim rejections for years. If a new hire says “I need to get an NPI,” ask whether they already have one — they almost certainly do. Look it up in the NPI Registry.
Getting the Type 2 NPI
1
Wait for the EIN
The Type 2 application requires the PC’s EIN. You cannot do this before Step 3 completes.
2
Create or use an I&A account
NPPES sign-in goes through CMS’s Identity & Access Management system. The person applying will be an authorized official of the PC, which, given officer licensure rules, is often the clinician-owner.
3
Apply at NPPES
nppes.cms.hhs.gov. Enter the PC’s exact legal name as it appears on the IRS EIN letter (CP 575), the practice location, mailing address, and taxonomy.
4
Name the authorized official
A person with legal authority to bind the PC. Their credentials matter for later changes.
5
Wait for approval
Typically a few days to two weeks. You’ll get the NPI by email.
Subparts
A Type 2 NPI can have subparts, additional organizational NPIs for distinct components of the same entity, such as separate locations or distinct service lines with different taxonomies. Most single-location practices do not need one. Multi-location groups sometimes do, particularly when a payer requires location-level identification. Do not create subparts speculatively; each one is another thing to enroll and maintain.Taxonomy codes
A taxonomy code is a 10-character alphanumeric code identifying a provider’s type, classification, and specialization, from the Health Care Provider Taxonomy Code Set maintained by the National Uniform Claim Committee.2 You select it during NPI registration and it appears on claims. Examples:
Two rules that prevent a great deal of pain:
- The taxonomy on the claim must match the taxonomy you enrolled with. A mismatch produces denials that look mysterious because nothing about the clinical content is wrong. This is a common root cause behind CARC 8 (procedure inconsistent with the provider type) and enrollment-related rejections.
- Group taxonomy and individual taxonomy are different things. The PC’s Type 2 NPI carries a group taxonomy (often the specialty, or
193200000Xfor multi-specialty); each clinician’s Type 1 carries their own.
CAQH ProView
CAQH ProView is a shared credentialing database. Rather than filling in the same 40 pages for every payer, clinicians maintain one profile and authorize payers to access it. Most commercial payers in the US use it. It does not replace payer enrollment — it feeds it.3Building the profile
The profile is per-clinician, not per-entity. For each clinician you will need:- Personal and demographic information
- Education, training, and board certification
- Complete work history with no unexplained gaps — this is the field that most often sends a profile back
- State license numbers and expiration dates
- DEA registration, where applicable
- Malpractice insurance certificate of insurance, with carrier, policy number, limits, and dates
- Hospital admitting privileges or the admitting arrangement if none
- Practice locations, including the PC’s address, hours, and languages spoken
- Disclosure questions (malpractice history, license actions, criminal history)
CAQH EnrollHub
Separate product, same organization. EnrollHub (also encountered as CAQH’s EFT/ERA enrollment tool) lets you submit bank account information once for EFT enrollment across participating payers, rather than filling in a separate form and voided check for each. Not every payer participates, but where they do it saves real time in Step 8. See Set up EDI, ERA, and EFT.Order of operations
Your artifact from this step
- Type 2 NPI for the PC, matching the CP 575 legal name exactly
- Type 1 NPI confirmed for each clinician (existing, not newly duplicated)
- Taxonomy codes selected and recorded for both
- CAQH profile complete, documents uploaded, payers authorized, and attested
- Re-attestation date on the compliance calendar
Checklist
- Searched the NPI Registry to confirm the clinician has no duplicate Type 1
- Type 2 NPI issued to the PC
- NPPES legal name matches the IRS CP 575 exactly
- Taxonomy codes chosen for both individual and group
- CAQH profile complete with no unexplained work-history gaps
- Malpractice COI uploaded
- Target payers authorized in CAQH
- Profile attested, with the re-attestation date calendared

Step 7: Open bank accounts
Payer money has to land somewhere the PC controls.
